Bit

The smallest unit of memory in the computer. A bit can be either off or on, representing a value of 0 or 1. Greater bit-depth translates to more complexity in image information.


Single-bit

Single-bit images use just one bit of data to record each pixel either black or white.


8-bit grayscale

Images that contain 256 possible shades of gray needed to represent most black-and-white photos accurately. 256 levels of gray is actually more shades of gray than the human eye can see.


24-bit color

24-bit color images are composed of three 8-bit color channels. When combined, the red, green and blue channels provide up to 16.7 million a possible combinations (hence, colors). 24-bit color is also known as True Color and photo-realistic color.


36-bit color

36-bit color images are composed of three 12-bit color channels. When combined, the red, green and blue channels provide up to 68.7 billion possible combinations that translate into that many "colors." (This compares to 16.7 million colors for 24-bit scanners.) The extra amount of information that can be processed by 36-bit scanners translates to more vivid color reproduction, as the scanner is able to accommodate more subtle gradations of color approaching lifelike accuracy.


Auto Document Feeder (ADF)

A scanner accessory that helps with text scanning. The ADF allows continuous scanning of up to 50 pages of text. This accessory is normally used with an OCR(Optical Character Recognition) software program, not an image-editing program like Adobe Photoshop or Microtek ImageStar II.


Brightness

The balance of light and dark shades in an image. Brightness is distinct from contrast, which measures the range between the darkest and lightest shades in an image. Brightness determines the intensity of shades; contrast determines the number of shades you get.


Color calibration

The process of ensuring accurate reproduction of color for images. Full color calibration is usually a two-step process: calibrating your input device, such as a scanner; and calibrating your output device, such as a printer or monitor. By calibrating input and output devices correctly, color is accurately captured by your scanner and is reproduced faithfully on your monitor or printer as well.


CCD

Stands for charge-coupled device, a strip of light-sensitive cells that converts light waves reflected from an image during scanning into digital information.


Color channel

Refers to the red, green, and blue components from which colors are created.


Color Image

An image type that contains the most complex information (compared to single-bit and grayscale images). To capture color images, scanners use a process based on the RGB color model.


Contrast

The relationship between the light and dark areas of an image. Contrast is the range between the darkest and lightest shades in an image, while brightness is the balance of light and dark shades. Contrast determines the number of shades you get; brightness determines the intensity of the shades. An image with low contrast tends to look dull and flat.


DCR

Stands for Dynamic Color Rendition, Microtek's exclusive color calibration and color correction technology. DCR ensures that reproduced colors in your scanned image match those of the original as closely as possible.


Dpi

Stands for dots per inch, the measure of resolution. The greater the dpi number, the higher the resolution.


Dynamic range

The ability of a scanner to register a wide range of tonal valuessomething from near white to near black. A scanner with good dynamic range is able to map input shades correctly to output shades, making images look brighter and with more visible detail. Generally, the number of bits determines the maximum dynamic range of a scanner. For example, a 36-bit scanner has a higher dynamic range than a 24-bit scanner.


Exposure

The amount of light in an image. The exposure of an image can be changed by increasing or reducing available light.


File format

The way a graphic file is saved. Several file formats are available for use, and each one has its own advantages and disadvantages. Among the most popular file formats are TIFF, PICT, EPS, and PCX.


Filters

Tools that allow you to apply or create special effects to your images. Filters in your scanning software include Blur/Blur More, Sharpen/Sharpen More, Emboss, Enhance Edges, and Unsharp Masking.


Gamma

The contrast affecting the mid-level grays or midtones of an image. Adjusting the gamma of an image allows you to change brightness values of the middle range of gray tones without dramatically altering the shadows and highlights.


Grayscale

An image type that contains more than just black and white, and includes actual shades of gray. In a grayscale image, each pixel has more bits of information encoded in it, allowing more shades to be recorded and shown. 4 bits are needed to reproduce up to 16 levels of gray, and 8 bits can reproduce a photo-realistic 256 shades of gray.


Halftone

A type of single-bit image composed of a pattern of black dots that fool the eye into seeing shades of gray. Examples of halftone images are the pictures you see in a newspaper. These images usually look very coarse.


Highlights

The lightest portions of an image.


Histogram

A graphic representation of how brightness and darkness pixels are distributed in an image. A histogram skewed heavily to the left indicates a dark image, while a histogram skewed to the right indicates a light image.


Hue

The aspect of color that distinguishes it from another color (what makes a color red or green or blue). Hue is distinct from saturation, which measures the intensity of the hue (more red, more green).


Image-editing software

Software that is used to edit images, such as Adobe Photoshop.


Image enhancement tools

Tools in your scanning software for adjusting the color and quality of images. These tools include Brightness, Contrast and Exposure; Shadows and Highlights; Tints; Curve;  Filters; and More Options.


Image Type

The way you wish an image to be scanned and processed. ScanWizard lets you reproduce an image as halftone, line art, grayscale, or color.


Imagesetter

An output device used to render high-resolution images or documents on photographic paper or film.


Interpolated resolution

Resolution enhanced through software; thus also known as software-enhanced resolution. For instance, if your optical resolution is 300 dpi you may be able to enhance images up to 600 dpi through software interpolation. Interpolated resolution is not as good as the optical, but it is useful for certain tasks, such as scanning line art or enlarging small originals.


Line art

A type of single-bit image that is just purely black and white, such as a pencil or ink sketch. Line art may also include one-color images, such as mechanical blueprmts or drawings.


Lpi (lines per inch)

The resolution of printed images. Lpi is distinct from dpi, which measures the resolution of electronic images.


Midtones

The parts of an image between the lighter and darker areas, at around 50% gray.


Moiré

An undesirable pattern in color printing that results from incorrect screen angles of overprinting halftones. Moirés usually result when you scan a halftone or when you scan images taken directly from a magazine (instead of scanning a photographic original or a transparency).


OCR

Stands for Optical Character Recognition, the process of scanning an image and converting the image into text format.


Optical resolution

The true resolution of a scanner and the key factor in determining the amount of detail visible in an image. Optical resolution is one type of resolution; the other is interpolated resolution.


Pixel

A unit used by the computer to describe picture elements and to represent image information in a digital format An image file, for instance, is simply a representation of hundreds (or thousands) of pixels arranged in a grid.


Printing methods

The type of printing method you choose should be tailored according to your scanned image. For instance, low-resolution black-and-white printers are good for producing text and line art, but they are not suitable for grayscale. For grayscale images, use higher-resolution printers  such as the ones capable of producing 600 to 1200 dpi To print color images, you can choose from ink jet/desk jet color printers, dye-sublimation printers, or  printing presses.


Resolution

The level of detail in an image, expressed in dots per inch or dpi The greater the dpi numb<, the higher the resolution and the resulting file size. There are two types of resolution: optical resolution, and interpolated resolution.


RGB

The color model in which every color is composed of a varying amount amount of the three colors of red, green, and blue.


Saturation

The intensity of a color, or the amount of color in a specific hue. For instance, the image of a bright red apple will appear to be "more red" if the colors are saturated.


Scanner

A device that captures an image for your computer and converts it to a digital form that your computer can display, edit, store and output A scanner can be used for a wide variety of applications, such as incorporating artwork or photos into documents, scanning printed text into your word processor to eliminate retyping, scanning faxed documents into a database for storage, and adding images to multimedia productions.


Scan material

The type of material for your image. Scan materials can be generally classified into three types: reflectives, such as photographs or prints; positives, such as slides; and negatives, like the negative film used in cameras.


SCSI

Stands for Small Computer System Interface, a format for interfacing hardware to the computer.


SCSI chain

A chain that links SCSI devices on your system. A SCSI chain may include such devices as a scanner, a CD-ROM drive, an external hard drive, and a tape drive. Each SCSI device on the chain must have its own SCSI ID number, or conflict will ensue.


Scaling

The process of creating larger of smaller images in ScanWizard, so that the images don't have to be resized later when they are delivered to the image-editing program. Scaling has an inverse relation to resolution: The lower the resolution, the larger the image can be scaled. At the highest resolution, images can only be scaled smaller.


Shadows

The darkest areas of an image.


Single-bit image

The simplest kind of image, using just one bit of data to record each pixel. Single-bit images come in two types: line art, and halftone.


Text scanning

One of the most common uses for scanners, as it eliminates the need for retyping. Scanners scan text through the use of OCR software and deliver text to your word processor.


Terminator

A piece of electrical equipment installed at the end of a SCSI chain. The terminator ensures that electrical impulses going through the path are properly routed and absorbed. Terminators act as a filter to clear out electrical "noise" caused by multiple cables and devices.


Transparent Media Adapter (TMA)

A scanner accessory used for scanning transparencies, slides and filmstrips. The TMA has a unique lighting device that prevents transparent originals from being exposed to too much light and getting washed out as a result.


Zoom

The ability to magnify the view of an image in the prescan window.

How to bring up ScanWizard for Windows

To bring up ScanWizard for Windows:

Start up your image-editing software. When the application opens, chose Acquire from the File menu, and choose Twain from the submenu.

The very first time that ScanWizard is started up, only the Preview and Settings windows will appear. To see the Scan Job and Information windows, go to the View menu and choose the Show command for both windows.

The next time you start up ScanWizard, your screen will look exactly like the last time you exited the software. This means that if you had all four windows open the last time you quit ScanWizard, the same four windows will appear the next time you start it up.


How to exit ScanWizard

To exit ScanWiz for Windows, double click on the close box on the upper left side of the Preview window.


How to select your scanner model

Choose the Scanner Model command from the Scanner menu.

The top of the scanner menu displays the scanner model you're using and its SCSI ID. If you have multiple scanners on your system, all the scanners are shown with their respective SCSI IDs, and the current scanner is indicated by a check.

Only one scanner can be accessed at a time. To switch among various scanners, select the scanner to be used.


How to get information the current scanner

Choose the Get Current Scanner Info command from the Scanner menu.

When you choose this command, a dialog box appears showing the scanner model, SCSI ID number, and firmware version.


How to use the Preview Setup command and its options

Choose the Preview Setup command from the Preferences menu.

This command allows you to set the dimensions of your preview area. When the Preview Setup dialog box comes up, click on the option you need or specify your parameters.

For more detail information, see the Preview Setup command.


How to use the rulers

The rulers on both sides of the preview window help you with operations that need precise measurement and alignment of your image.

The unit of measurement in the rulers is determined by the unit of measurement you have selected. This can be done either in the Image Dimension controls, located in the Settings window, or by clicking on the ruler unit button at the 0,0 point of the rulers in the Preview window.

Depending on your chosen unit of measurement, the rulers can mark off measurement in these units: inch, centimeter, millimeter, point, and pixel. The pixel option is dimmed if the selected resolution unit is lip.

To select the unit of measurement for the rulers:

Click on the unit box in the Settings window, or click on the ruler unit button at the 0,0 point of the rulers in the Preview window. When the submenu appears, select the unit of measurement.


How to use the Preview button

The Preview button gives you a preliminary view of the image on your scanner.

Previewing an image gives you greater flexibility, as it allows you to apply various controls to the preview image before actually scanning it in. With the preview image displayed, you can apply image enhancements or crop the image before performing the final scan.


How to use the scan button

The Scan button lets you scan the image in your scanner  and delivers it to your image-editing software. The scanned image is based on the specifications you have chosen in the Settings window and on controls you may have applied to the preview image if a preview was performed.


How to use DCR (Color Correction)

The DCR utility controls the Color Correction feature in the ScanWizard.  DCR comes standard on certain scanners; for scanners without DCR, a generic color profile is still included  for color correction.  For scanners with DCR then, clicking on the Color Correction button will activate DCR. For scanners without DCR, clicking on the Color Correction button will activate the generic color profile.

If you have DCR, you need to calibrate your scanner first for the DCR filter to be applied when you scan. Otherwise, ScanWizard will simply apply the generic color profile for color correction. The calibration process will vary, depending on the type of scanner you have.

To calibrate color flatbed scanners:

Place the target that came with the DCR kit face down and upside down on the scanner. Center the target along the horizontal ruler of the scanner.

To calibrate transparency scanners (ScanMaker 45t)

Hold the target so that you can read the writing on it, and place it in the transparency holder. Then slide the holder into the scanner.

To calibrate slide scanners (ScanMaker 35t)

Hold the target so that the text on the slide reads normally (not backwards), then insert the slide into the scanner.

To calibrate color flatbeds with Transparency Media Adapter (TMA) attached

The TMA can be calibrated for either reflective or transmissive mode. Calibrating the scanner with TMA for reflective mode allows you to scan photos and prints; calibrating the scanner with TMA  for transmissive mode allows you to scan transparencies.  Calibrating in both modes enhances your scanner functionality.

To calibrate for reflective mode:

1.	Turn off the scanner, then place the 8 1/2" x 14" template that comes with your TMA on the scanner glass. The template should be placed snugly within the glass area, with no overlapping on the horizontal or vertical rulers of the scanner. When the template is placed correctly, turn on the scanner.

2.	When the scanner comes to ready, place the reflective target that came with your DCR kit  inside the template. The target should placed face down  and upside down on the scanner, centered along the front edge of the template.

To calibrate for transmissive mode:

Do not use the templates, then follow #2 above. Instead of using the reflective target, however, you must use the transmissive target that came with your TMA package.

To start calibrating:

1.	Launch Windows.

2.	Go to the ScanWizard group window, and double-click on the Microtek Calibrator icon.

3.	When the Calibrator dialog box opens:

•	For color flatbed scanners, click on the Reflective option, then click the Calibrate button.

•	For scanners with a TMA, click on the Reflective option if you are calibrating for reflective mode; or click on the Transmissive option if you are calibrating for transmissive mode. Then click on the Calibrate button.

How to use the Color Picker tool

The Color Picker tool allows you to sample color from an area of an image and to designate a new shadow or highlight point.

With the Color Picker tool, you can determine the color values for any pixel in an image. When you click on the Color Picker tool and pass over a pixel, the value of that pixel will be displayed in the Information window, based on the samples size also selected in the Information window. Pixel-value information is useful especially when you're making color adjustments based on color values.


How to change the sample size of the Color Picker

To change the sample size of the Color Picker:

1.	Open the Information window by choosing the Show Info Window command in the View menu.

2.	Click on the Sample Size button, located to the right of the RGB values in the Information window.

3.	Choose your options.

•	Select Value or Percent to determine how the pixel information will be displayed.

•	Select the sample size. For instance, the 1 by 1 option will display the value of one pixel -- the one in the middle of the Color Meter Display. The 3 by 3 option reads the average value of a 3-pixel by 3-pixel area.


How to display color information for a pixel or an averaged area

To display color information for a pixel or an averaged area:

1.	Click on the Color Picker tool.

2.	As you pass over a point in the image, see the Information Window the RGB values will be displayed in the Color Meter Display. These values are in turn based on the sample size you selected.


How to select a new shadow or highlight point

To select a new shadow or highlight point:

1.	Click on the Color Picker tool, then click on the Window Expansion button to see the bottom half of the Settings window.

2.	Select a color channel in the channel box.

3.	To select a new shadow point, click on a pixel that will serve as the new shadow point.

To select a new highlight point, hold down the Shift key as you click; the Color Picker tool will change and become a white-colored eyedropper.


How to restore original settings

To restore original settings:

1.	Click on the Window Expansion button in the Settings Window to see the bottom half of the Settings window.

2.	When the expanded window appears, click on the Reset button. When a dialog box appears, click on Shadows and Highlights, then click on Reset to close the dialog box.


How to use the AIE dialog box

When you click on any of the Image-enhancement tools in the Settings window, the Advanced Image Enhance (AIE) dialog box appears. In this box, you can do the following:

1.	This is where you select the scan job which image enhancement will be applied. (Note: For definition of a scan job, see the Scan Job section of the Reference.) If you have multiple scan jobs, you can switch among the various jobs, and the thumbnails will change accordingly to show the selected scan job.

Important:
Switching to a new scan job while using the AIE dialog box will make any changes to the currently selected scan job permanent. This cannot be undone even by selecting the Cancel button.

2.	These are the thumbnail of the image captured by your scanner. The left thumbnail is the "before" version -- which shows the effects of the last saved settings values. The "right thumbnail is the "after" version -- which shows the effects of the new settings added in the AIE.

3.	To select another image-enhancement tool, click on any of the buttons displayed in the vertical toolbar on the right side of the dialog box.

4.	Click on an action button to achieve a particular effect.


How to use the action buttons in the AIE dialog box

Click on an action button to achieve a particular effect. The Action button in the AIE dialog box carry out a specific action.

The OK button

Clicking on this button will apply whatever image enhancements you have performed on the current scan job, and close the AIE dialog box. Clicking OK is not the same as switching to another scan job (if you have multiple scan jobs). If you switch scan jobs, the effects are applied to your current scan job, and then the new scan job shows up; you do not exit the AIE dialog box.

The Cancel button

Clicking on this button will cancel out all image-enhancement changes you have made to the current scan job, and then close the AIE dialog box.

The Reset button

Clicking on this button brings up the Reset dialog box, where you can specify which settings are to be reset, then click Reset or Cancel. If Reset is selected, the settings are restored to their default values; if Cancel is selected, the operation has no effect.

The Revert button

Clicking on this button cancels out the changes you made with the current image-enhancement tool. This means that if you used several tools (and achieved a look that is the cumulative effect of all the tools), using Revert will cancel the effect of only the current tool and preserve the effects of the other preceding tools.


How to use the windows expansion button

The Window Expansion button lets you expand the Settings window to its full size, with the bottom half of the window revealing the image-enhancement controls.

When the bottom half of the Settings window is open, you can use the image-enhancement functions directly by dragging on the slide bar for each control. This is like clicking on the image-enhancement tool, which takes you to the Advanced Image Enhancer (AIE) dialog box where you can change the controls.

Using the slide bars to adjust images may be faster, but using the image-enhancement tools gives you greater control over adjusting images and shows you "before-and-after" images in the AIE dialog box.

To close the bottom half of the window, click on the Window Expansion button again.


How to use the Type

To use the Type menu:

•	From the Type menu select the image type for your final scan. Choose the correct image type, as the wrong choice will simple create bigger files that won't be of any use to you. For instance, if you have a grayscale original, do not set image type to Millions of colors.

•	If you select Halftone, choose the halftone screen as well from the submenu.


How to set Resolution

To set resolution:

Enter a resolution setting in the Resolution edit box. There is no need to press the Enter key; typing in a value automatically inputs it into the system. If the value you enter is too low or too high, the minimum or maximum resolution value is entered for you instead.

Note: In setting resolution, choose the setting that best matches your output device. Remember that the higher the resolution, the larger the resulting file will be and the longer it will take to output.


How to select the resolution unit

To select the resolution unit:

•	Choose dpi if you know precisely the resolution you need for your image. For more details on resolution, see the Basic Concepts chapter in the manual.

•	Choose lpi Draft to produce resolution that is one times the screen frequency (no higher than 72 pixels per inch). Draft quality may result in output images that look a little blurred or indistinct at edges.

•	Choose lpi Medium to produce resolution that is one and one-half times the screen frequency.

•	Choose lpi Final to produce resolution that is two times the screen frequency.


How to use the Image Dimension controls

To use the Image Dimension controls:

•	Select the unit of measurement.

•	Enter a value in the applicable edit boxes (width input, height input, scaling, width output, height output).


How to use the Input-Output dimensions

•	Use the input dimensions to specify your scan frame; or simply drag on the scan frame to whatever size you want, and the dimensions will be reflected in the input width and height boxes. Input dimensions can be changed only if the Aspect Lock is off

•	Use the output dimensions to determine the width and height of your image when output to an output device such as a monitor or printer. Output dimensions can be changed only if the Aspect Lock is on.

•	Output dimensions are calculated dynamically, and the system looks at other variables such as resolution and scaling to determine the final output dimensions. This means that you may specify output dimensions of 5" x 7", but because of intervening variables, the actual output dimensions may be 4.85" x 6.9" -- which is the closest the system can produce given your other variables.


How to use the Aspect Lock

The Aspect Lock preserves the ratio of the image width and height from input to output. For instance, if you image is 2 inches wide by 4 inches high, changing it to 1 inch by 2 inches will maintain its aspect ratio. Changing it to, say, 1 inch by 4 inches, however, will alter its aspect ratio, so that the image will be narrower than the original.

•	If Aspect Lock is ON:

Changing one output edit box (width or height) will automatically change the other output field, as well as scaling, to preserve the aspect ratio. With Aspect Lock on, you cannot edit the input dimensions.

Important:

•	If you change any of the output fields, you must highlight the other output field or the scaling for the system to change the other output field. The system will then make the calculations automatically to preserve the aspect ratio.

•	If Aspect Lock is OFF:

Changing one input edit box (width or height) will NOT automatically change scaling or the other input field, and aspect ratio can be changed. With Aspect Lock off, you cannot change the output dimensions.

To use the Aspect Lock:

Click on the Aspect Lock to lock it; click on it again to unlock.


How to use Scaling

Scaling is the process of creating larger or small images in your scanning software so that you need not resize the images later when they are delivered to your image-editing program.

To illustrate the use of scaling: Assume that your input dimensions are 4" x 5", then:

•	If scaling is at 100%, output dimensions will also be 4" x 5".

•	If scaling is at 50%, output dimensions will be halved -- to 2" x 2.5".

•	If scaling is at 200%, output dimensions will be doubled -- to 8" x 10".

The above assumes that your resolution is held constant throughout the changes. When you change resolution and specify a value that has no exact equivalent for scaling, the scaling may be affected and adjusts itself to the nearest allowed value. For instance, if resolution is 100, scaling becomes 99 (instead of a full 100), because that is the closest scaling equivalent, given the resolution value.


How to use the Auto control

To use the Auto control:

1.	Click on the Preview button to preview the image.

2.	Click on the Scan Frame tool, and draw a scan frame of the area where Auto will be applied.

3.	Click on the Auto button in the Settings window. The button is checked, indicating that Auto has been applied.

If you do not like the results obtained by Auto, or if you choose not to use it for certain images that have Auto enabled, click on the Auto button again to deselect the feature.


How Auto settings are applied

The Auto setting works by calculating the image settings of the current scan frame and applies those settings to the current scan frame.

If you draw a scan frame around part of an image that is light and then apply Auto, the part of the image within the scan frame becomes darker. This is because Auto takes that dark portion and remaps the pixels to a broader range. The light pixels are then spread further apart, resulting in a darker image.

Conversely, if your scan frame encloses a darker part of the image and then you apply Auto, the image part within the scan frame becomes lighter.  The dark pixels are remapped to a broader range, resulting in a lighter image.

When you use Auto, it is helpful to turn on the Smoked Glass Background feature (in the Preferences menu in the Preview window). This will allow you to see clearly the part of the image within the current scan frame.


How to use the BCE tool

To use the BCE tool:

1.	To change brightness or contrast, choose the Brightness or Contrast control. To change values, drag on the slide bar or click on the arrows at either side of the bar.

2.	To change exposure:

•	Click Cancel to abandon all changes and exit the AIE dialog box.

•	Click Reset to restore settings to the original default values.

•	Click Revert to cancel the effect of the current image-enhancement tool.


How to use the Tints Tool

To use the Tints tool:

1.	To change the hue of an image, move the pointer in the color wheel to its new color position in the wheel.

2.	To change the saturation of an image, drag on the saturation slide bar. Dragging the slide bar to the left decreases saturation; dragging it to the right increases saturation.

3.	For negatives only:

•	To choose the correct film type for your negative, click on the Film Type Selection box and make your selection. If your film type is not in the list, select Generic Film Type.

•	To correct the exposure of a film, use the Exposure Correction bar. To correct overexposure and make the film darker, drag the triangle to the left. To correct underexposure and make the film lighter, drag the triangle to the right.

4.	Click on an action button.

•	Click OK to accept the changes and exit the AIE dialog box.

•	Click Cancel to abandon all changes and exit the AIE dialog box.

•	Click Reset to restore settings to the original default values.

How to read and correct a histogram

A histogram shows how the brightness and darkness levels are distributed in an image. The darkest pixels are at the left, and the lightest pixels are at the right.

An image with good contrast will have a histogram with vertical lines spread across the scale from left to right. To change the histogram (and thus the image), use the three triangles below the histogram.

In the original histogram, the pixels are mostly to the left where the black triangle is, indicating a dark image. The range of spread also broad and flat, with almost no pixels for the midtones and highlights where the gray an white triangles are.

In the corrected image, the triangles have been moved to new locations. The net effect is to narrow the distribution range of the pixels and lighten the image.

Generally, the best thing to do is to move the black and white triangles to the start and end of the curve.

For example, if you graph starts at about value 20 and ends at 240, then move the black triangle to 20 and the white triangle to 240. Move the gray triangle to somewhere in the middle between the black and white triangle.


How to use Shadows and Highlights tool

To use the Shadows and Highlights tool:

1.	Choose the channel in which the histogram will be modified.

•	Select Master to modify the histogram in the red, green, and blue color channels simultaneously.

•	Select color channels individually (red, green, blue) to modify the histogram in that particular channel.

•	For grayscale scanners, only the gray channel is available.

2.	Move the black, gray, and white triangles to change shadows, midtones, and highlights, respectively. The values in the input edit boxes will change accordingly.

•	To make the image darker, move in the black triangle to the right.

•	To make the image lighter, move in the white triangle to the left.

•	To change the midtones, move in the gray triangle. If the midtone value is less than 1, the image will be darker. If the midtone value is greater than 1, the image becomes lighter.

3.	Click on the Display box to view histograms of the original image and the resulting (Enhanced) image.

•	Select Original to see the histogram before changes were made to the image.

•	Select Enhanced to see the histogram after changes were made to the image.

4.	Click on an action button.

•	Click OK to accept the changes and exit the AIE dialog box.

•	Click Cancel to abandon all changes and exit the AIE dialog box.

•	Click Reset to restore settings to the original default values.

•	Click Revert to cancel the effect of the current image-enhancement tool.


How to read the Curve

The curve shows the relationship of the brightness changes across the middle pixels between the resulting image and the original. When you open the Curves dialog box, the line on the graph is diagonal because the Input and Output values are the same.

The x axis of the graph represents the original brightness values of the pixels, from o to 255; the y axis represents the new brightness values. Clicking on the diagonal line then plots a point that can be adjusted.

When the curve is moved up or down, the relationship between input value and output value changes accordingly.

•	In areas where the curve is moved down, pixels in that portion of the image are darkened.

•	In areas where the curve is moved up, pixels in that portion of the image are lightened.

Contrast in an image can be seen by the angle of the line. The steeper the slope. the higher the contrast. The closer the line is to horizontal, the lower the contrast.


How to use the Curve tool

To use the Curve tool:

1. Choose the channel in which the curve will be modified.

•	Select Master to modify gamma in the red, green, and blue color channels of the image simultaneously.

•	Select color channels individually (red, green, blue) to modify gamma in that particular color channel.

•	For grayscale scanners, only the gray channel is available.

2.	Choose the Method in which the curve will be modified; select from Line, Curve, or Gamma. There is no difference in the method you select, and the choices are provided to give you more flexibility in adjusting the curve.

3.	Choose a curve button; select from Pointer, Zoom Frame, or Hand.

•	Use the Pointer button to define points in the curve that will be modified. When you click on any point in the curve, a control point appears to mark your position. To remove a control point, drag it off the graph.

•	Use the Zoom Frame button to zoom in on a particular point in the curve. Once the area is zoomed in, you can then use the pointer tool to define new points for more precision. This is particularly useful for working with 12-bit images, as more detail can be seen in such images. The zoom level can be seen in the Zoom column.

•	Use the Hand tool to scroll through the curve if the curve has been zoomed in. The Hand tool can be used only if the curve has been zoomed in with the Zoom Frame button (above). Otherwise, the Hand tool will be dimmed.

4.	Click on the curve to define the points where the curve will be modified.

Once you click on a point in the curve, a control point appears to mark your position. You can then either raise or lower the curve at that point and see changes to the image accordingly.

5.	Click on an action button.

•	Click OK to accept the changes and exit the AIE dialog box.

•	Click Cancel to abandon all changes and exit the AIE dialog box.

•	Click Reset to restore settings to the original default values.

•	Click Revert to cancel the effect of the current image-enhancement tool.

6.	To save a curve, click on the Save button. A dialog box will appear.

•	Save the curve in Microtek format. The Microtek format allows you to have as many as 64 control points in the curve for more precision.

•	Choose the Channel. Select All if your channel is Master, select Current if you selected one of the three color channels (red, green or blue).

To use a previously saved gamma curve for another image, click on the Load button, then specify the curve to be loaded. Photoshop-saved curves can also be loaded.


How to use the Curve buttons

The Curve buttons allow you to modify the curve in the Curve dialog box.

•	Use the Pointer button to define points in the curve that will be modified. When you click on any point in the curve, a control point appears to mark your position. To remove a control point, drag it off the graph.

•	Use the Zoom Frame button to zoom in on a particular point in the curve. Once the area is zoomed in, you can then use the pointer tool to define new points for more precision. This is particularly useful for working with 12-bit images, as more detail can be seen in such images. The zoom level can be seen in the Zoom column.

•	Use the Hand tool to scroll through the curve if the curve has been zoomed in. The Hand tool can be used only if the curve has been zoomed in with the Zoom Frame button (above). Otherwise, the Hand tool will be dimmed.


How to use the Filters tool

To use the Filters tool:

1.	Click on the Filters tool in the Settings window. When the Advanced Image Enhancer dialog box appears, click on the Filter box, and from the drop-down menu that appears, select the filter to be used.

2.	Click on an action button.

•	Click OK to accept the changes and exit the AIE dialog box.

•	Click Cancel to abandon all changes and exit the AIE dialog box.

•	Click Reset to restore settings to the original default values.

•	Click Revert to cancel the effect of the current image-enhancement tool.

3.	To preview filters and see their effects immediately, click on the box Show Filter Effect on Preview Image.


How to use Unsharp Masking

1.	Choose Unsharp Masking from Filters menu. The Unsharp Mask dialog box appears.

2.	Enter a value in the Amount box to specify the percentage of the filter's effect. The higher the percentage, the stronger the effect of the filter.

3.	Enter the Radius value in pixels. The radius determines the depth of pixels that will be affected at the edge.

•	With a high value, more of the pixels surrounding the edge pixels are sharpened.

•	With a low value, only the edges are sharpened.

4.	Enter a value in the Threshold box.

This option allows you to specify a tolerance range to prevent overall sharpening that might generate noise or cause other unexpected results.

The Threshold defines the required range of contrast between adjacent pixels before sharpening is applied to an edge. A lower value produces a more pronounced effect.


How to use the Gray Scan CCD Filter

This option allows you to select a particular color channel when scanning grayscale images and is useful for obtaining certain effects.

When scanning grayscale images, one of the color channels of the CCD can be used scanning; this could be the red, green, or blue color channel.


How to use the Scan Quality

This option allows you to select the quality of your scans.

Choose Draft if you're outputting images as drafts. This option speeds up the scanning process, but the image may be a little coarse (compared to the Final option).

Choose Final if you wish to have a scanned image of better quality. This option, however, is slower than Draft.


How to use the Linear Gamma Curve

This option allows the scanning software to read only raw image data, so that no color adjustment (not even the generic color correction profile) is applied to your image when it is scanned.

This control is helpful for professional graphic designers who wish to create very specific effects and are thoroughly familiar with the scanning process. If you are not familiar with this feature, leave this option turned off.


How to use Descreen

To use Descreen:

1.	Click on the More Options tool in the Settings window.

2.	When the More Options screen comes up, click on the Descreen box and select your descreen option. The option you select will depend on the dot quality of the original.

•	Choose Newspaper if the original image has a coarse dot pattern (like images in a newspaper).

•	Choose Magazine for images with a finer dot pattern.

•	Choose Art Magazine for images with near-photographic quality with a very tight dot pattern.

•	Choose Custom for customized descreen options.

A check appears next to the descreen option that is enabled.

Note: Because of the nature of this filter, scans may take longer if you use the Descreen feature


How to use Velocity

To use Velocity:

Click on the More Options tool. When the dialog box comes up, click on the Velocity box and select your scanning speed

Important:
Sometimes certain scanner models on certain configurations appear to make noise when scanning. This could be normal and may be related to the speed at which the carriage is moving. Changing the velocity can change the amount of noise or type of sound made by the scanner. The action of previewing and scanning can also generate different noises, but this is no cause for alarm.


How to use the controls in the More Options tool

Click on the More Options tool in the Settings window. When the More Options screen appears, select the particular control to be modified and its option, then click OK.


How to read the Scan Job window

1.	The example show three scan jobs.

•	The first scan job, entitled Default Scan #1, is a color image.

•	The second scan job, entitled Default Scan #2, is a color image.

•	The third scan job, entitled Default Scan #3,  is a duplicate that shares the settings of the second scan job.

The current scan job is the first scan job (Default Scan #1), which is highlighted to mark it as the current scan job. All three scan jobs will be scanned, as each is marked with a check. To change the order in which the jobs will be scanned, use the up and down position arrows to change the sequence of the titles.

2.	The image-type icon in front of the scan job title shows the scan job type -- whether it is color, grayscale, line art, or halftone. A color scan job will have a color image-type icon; a grayscale scan job will have a gray image-type icon; and a line art or halftone scan job will have its corresponding image-type icon.


How to use the New button

To use the New button:

1.	Click on the Preview button to see a preliminary view of the image.

2.	When the preview image appears, draw a scan frame that covers the left half of the image. At this time, your scan job area shows the title of the current scan job (Default Scan #1. Make sure the image type selected (in the Settings window) for this scan job is Millions of colors.

3.	Click on the New button in the Scan Job window. When a dialog box comes up, give a title to the new scan job, then click OK. In this example, the new scan job is called Default Scan #2. The Scan Job window will now have two titles. At the same time, a new frame appears in the preview window.

4.	Draw the second scan frame around the right half of the image. In this case, confine the scan frame to the upper right half; leave the lower right half free. The reason why will become apparent in the next step.

5.	With the title bar in the Scan Job window highlighting the second scan job, go to the Settings window, then choose 256 shades of gray in the Type box. Next, go to the Preferences menu in the Preview window and enable the Smoked Glass Background command.

You will now see the following:

•	The second scan job (the upper right half of your image) is in grayscale.

•	The first scan job (the left half of the image) remains in color.

•	The lower right half of the image (the part not included in any scan frame) is hidden behind the smoked glass background. The smoked glass command is not essential for doing a scan job, but it helps you distinguish scan frames more easily.

6.	To see how the scan jobs relate to the titles in the Scan Job window, try this.

•	Click on the first scan job title. The scan job that becomes active will be the left half of the image (in color). In the Scan job window, the title will be highlighted, indicating that it is the current scan job.

•	Click on the second title, and the second scan job is activated (upper right-hand part of image, in grayscale). The second title is now highlighted, because it is the current scan job.

7.	To designate the scan job to be processed and scanned, select the scan job and click on the Check button. The checked scan job(s) will then be scanned in the order that they appear in the Scan Job window, and they will be delivered separately to your image-editing software.


How to use the Duplicate button

To use the Duplicate button:

1.	Click on the Preview button to see a preliminary view of the image. To show the principle of duplication clearly, choose image type (in the Settings window) as Millions of colors. Also turn on the Smoked Glass Background feature (in the Preferences menu of the Preview window).

2.	Draw a scan frame around a part of the image. This is your current scan job.

3.	To see the effects of duplication clearly in the steps that follow, set the image type of the current scan job to 256 Grayscale. You will see the current scan job as a grayscale job, while the rest of the image behind the smoked glass background remains in color.

4.	Click on the Dup button. Draw another scan frame around a different part of the image; this is your duplicate scan job. You will see that the duplicate scan job will also be in grayscale, as it shares the settings of the current scan job. In the Scan Job window, there will be two titles, and the duplicate scan job is the one with a number to it.

Shortcut to creating duplicate scan jobs:

Hold down the Shift key and dray the mouse. A duplicate scan job is created based on the current scan job, and a duplicate title is added in the Scan Job window.


How to use the Save button

Click on the Zoom Level box. From the drop-down menu that appears, select your zoom or magnification level.


How to use the Cursor Locator

The Cursor Locator shows you where the cursor is on the x (horizontal) and y (vertical) coordinates of the axis. This feature is useful for operations that require very precise measurements and alignment.


How to use the Color Meter Display

The Color Meter Display is useful if you wish to adjust the shadow and highlight points of an image.

As you pass over a point in the image, the Color Meter Display will show the appropriate RGB values of that point in the image.


How to use the Sample Size button

The Sample Size button provides options for choosing how extensively the color information will be read whether the color information will apply to a pixel, a  2-pixel by 2-pixel area, or a wider expanse (maximum 5-pixel by 5-pixel area).

When you click on the Sample Size button, the drop-down menu appears.


How to use the Pixel Display

The Pixel Display helps you see how color pixels are organized and distributed. The display can then help you make an informed judgment on how best to modify image characteristics such as  shadows and highlights, and also allow you to verify any changes that are made.


Troubleshooting

1.	If the POWER indicator fails to light up

19.	You are unable to use the Auto Document Feeder (ADF)

20.	You get this message: "Kodak Precision CMS not found or there is insufficient memory to initialize it..."

21.	The KCMS Acquire option is not present


1.	If the POWER indicator fails to light up

Solution:

Turn off the scanner. Make sure the scanner's power is grounded and plugged into an AC outlet. Wait 60 seconds, then turn on the power again. Microtek scanners have a protective mechanism that prevents the scanner from coming on right away after it's just been turned off to increase the life of the power supply.


2.	The scanner's READY light does not come on; you do not have a Transparent Media Adapter.

Solution:

Check the fluorescent lamp inside the scanner and make sure it is continuously and solidly on. Take note of the following:

•	If the lamp is on and the scanner still doesn't come ready, the problem may be related to temperature. For example, you may experience problems of this sort if you live in cold weather and the scanner is left in a room all night without the room's heater on.

To resolve this situation, leave the scanner on for 30 minutes to warm up, then turn it off and back on after 60 seconds, and see if you get a steady READY light this time.

•	If the lamp still doesn't come ready, do one of the following:

a)	If you purchased your scanner within the past 30 days, call your dealer.

b)	If your purchased your scanner more than 30 days ago, call the nearest service center or Microtek directly.

If your lamp is on and the READY light is on but the scanner doesn't scan or doesn't seem to work, try testing the scanner to see if it is a scanner-related hardware problem. To do this, disconnect the scanner from the computer, set the SCSI ID to #7, and turn it on. The scanner will scan continuously. If it does not, there is a hardware problem. Contact your dealer and tell them the situation.


3.  The scanner's READY light does not come on; you have a Transparent Media Adapter attached. (Also see troubleshooting tip #
3.	The scanner's READY light does not come on; you have a Transparent Media Adapter attached. (Also see troubleshooting tip #13.)

Solution:

Disconnect the Transparent Media Adapter (TMA) and see if the scanner comes ready this time. If not, see the solution outlined in situation #2.

If the scanner comes ready on its own but doesn't come ready if attached to the TMA, you may have a problem with the gray template that comes with the TMA, or you may have a problem with the external power supply.

To resolve this situation, check the following:

•	Make sure you have an external power supply (included with the TMA if needed) if your scanner model (such as the ScanMaker IISP) requires one. The power supply is needed for the TMA to function.

•	Make sure the TMA model matches your scanner (check the outside of the TMA box to verify this). If you have the wrong or mismatched TMA model, call your dealer and exchange it for the correct one.

•	Next, install the TMA (and the power supply if it has one), and close the TMA top. Make sure that nothing is placed inside the scanner on the glass surface and then turn the scanner on. You should now get a ready light.

If your lamp is on and the READY light is on but the scanner doesn't scan or doesn't seem to work, try testing the scanner to see if it is a scanner-related hardware problem. To do This, disconnect the scanner from the computer, set the SCSI ID to #7, and turn it on. The scanner will scan continuously. If it does not, there is a hardware problem. Contact your dealer and tell them the situation.

4.	When issuing a Scan command, the software locks up after the scanner seems to start scanning (make "noises"); or you get an error message.

4A.	If you have the Transparent Media Adapter:

Make sure the TMA is installed properly (see situation #3 for more details). In addition, make sure you observe the following:

•	Place the gray template that comes with the TMA on the glass surface of the scanner, with the clear opening of the template towards the front of the scanner.

•	Place the transparency to be scanned inside the template, and close the cover.

•	In the scanning software, select either Positive or Negative from the Scan Material command in the Preferences menu (depending on whether you're scanning a positive or negative transparency); do not use the Reflective option.

•	After complying with the above, click on Scan or Preview.


5.  With the scanner connected, the Mac won't boot up or locks during boot up.
5.	When you scan an 8-1/2-inch wide image, the left or right side of the image is cut off.

Solution:

This may happen if you are using a ScanMaker III scanner, which has a maximum scanning width of 8.3 inches. Therefore, a small margin on each side will be cut off when you scan.


6.	The scanner makes loud noises when scanning.

Solution:

Certain scanner models make different noises when scanning. The noise results from the mechanical parts moving at various speeds, depending on your configuration, so some systems have more noise while others have less. The noise is greatest when the velocity is set to Fast or Auto. To resolve this, set the velocity in the scanning software (in the More Options tool in the Settings window) to Medium or Slow to reduce the noise.


7.	While scanning images, the scanner carriage (lamp) keeps going back and forth or idles, resulting in very long scan times.

Solution:

This is called backtracking. Microtek scanners have a feature that allows for recovery from image defects that result from the carriage scanning and stopping during the scan. The carriage usually goes back and reads part of the image once, then goes back a second time to patch the images together and create a smooth picture. On some machines, due to low amount of memory or a large virtual memory size, the software forces the scanner to stop and start too many times, causing backtracking.

To resolve this, you can:

•	Increase RAM in the computer by purchasing more memory.

•	Reduce or turn off virtual memory in the Windows 386 Enhanced module inside the Main group window.

•	If using the Omnipage Direct software, turn off the Auto Intensity feature under the Options menu.


8.	Your scanned images do not have the same color as the original.

Solution:

Generally, scanners, monitors, and printers all see and output color differently. In order to come close the original colors, you need to calibrate all three devices. Microtek 's DCR color correction system ensures that your scanner capture colors accurately, but to have these colors output correctly to a monitor or printer, you need a color management system such as Kodak's Color Management Software, or AGFA's Color Calibration System. These third-party color management systems ensure color Integrity throughout the color production process from input to output. Usually, all scanners scan a little darker or lighter than the original (for instance, a scanner may scan red as magenta). This is not a fault of the scanner but a situation inherent to calibration of the equipment.


9.	Scanned images have vertical white lines from top to bottom.

Solution:

The mirrors of your scanner may be dusty or dirty. To resolve this, open the cover and spray some air on the bottom mirror which is roughly 8-1/2" long and is directly below the carriage (but moves with the carriage). Do not clean the mirrors with glass cleaners such as Windex or with cloth. If you want to use a liquid, use alcohol and lens tissue paper (other materials may scratch).


10.  When you select Acquire, the Microtek scanner software reports that no scanner is connected, or the Model, Scan, and
10.	When you select Acquire, the Microtek scanner software reports that no scanner is connected, or the Scan and Preview buttons are grayed out.

Solution:

This problem usually happens when the software cannot see the scanner. This situation could be resolved by any of the following:

•	Make sure the scanner has a solid green light on and that the lamp inside is continuously and solidly on (no flickering). If not, see troubleshooting for situation #2.

•	Make sure the scanner is connected properly to the computer. If you have multiple SCSI devices connected to your computer, try the computer with only the scanner connected to see if the two work. If they do, the problem is with another SCSI device or with the cabling. Make sure none of your cables are too long (4 feet or shorter), and make sure the last SCSI device on your system is externally terminated with a terminator.

•	Set the Windows display option to VGA or super VGA, then restart Windows and try again. The problem may be a conflict with the video driver.

•	Turn off 32-bit addressing in the 386 Enhanced module of the Main group window, then restart Windows and try again.

•	Make sure the SCSI ID setting on your scanner is unique, and that no other SCSI device has the same setting as your scanner. Microtek scanners are set to SCSI ID #6 by default. If you have a utility that can scan your SCSI bus (such as ScanWizard's   SCSI Check feature), you can easily find out what ID numbers are taken and which ones are free to be used for the scanner.

•	You may also want to try to scan using the Scanner Test utility to see if the problem is in your image-editing software or due to other conflicts between the software and another program in your computer. If the test utility works, then your scanner is operating properly, and you can then look for other utilities and programs that may be causing the problem.


11.	The Photoshop File-Acquire option is grayed out, and you cannot select the option for your Microtek scanner.

Solution:

When you installed Photoshop, you installed for minimum configuration and did not install the Plug-ins option. You need to reinstall Photoshop, and during installation, you must specify that the Plug-ins are to be installed as well.


12.	Color images are washed out with little detail in the light or highlight areas.

Solution:

Sometimes on certain images that are light, enabling the Color Correction option or the Auto button (both in the Settings window) might make the images very light and thus cause certain areas to wash out. To resolve this, you may want to turn off these options.

Also, if you are scanning very light highlight areas and they're coming out white, try reducing the exposure control (through the Brightness, Contrast and Exposure tool) to a negative number.


13..Color image seem to have a pattern on them when scanned.
13	Color images seem to have a pattern on them when scanned.

Solution:

Check the following:

•	Make sure that your monitor option in your Windows setup is set to 16.7 Millions of colors.

•	If you scan an image that came from a magazine or brochure, you will get an artifact on the image called moiré. Moiré patterns show up when you Scan an image that has been printed already. To reduce the patterns, select the More Options tool in the Settings window, and then select the Descreen filter. In the Descreen filter are options for newspaper, magazine, art magazine, and custom. For more details, refer to the Reference section in the manual.


14.	Problems with the Transparent Media Adapter (TMA)

Solution:

Check the following:

•	If you have a ScanMaker II scanner, make sure your TMA is of a matching model (TMA for the ScanMaker II). If not, call your dealer and exchange the TMA for the correct one. Also, older ScanMaker ll scanners may not work with the TMA unless you upgrade the board inside the scanner. Take note of the following:

1.	If the serial number on your scanner is above S2B5720701 or below, call Microtek to arrange for a scanner upgrade; the upgrade costs $350.

2.	If the serial number on your scanner is above S2B5720701 (ex. S2B5720702), your scanner needs to have Firmware version 5.61. The firmware version of your scanner is marked on the scanner box as F/W: version number . If you do not have firmware version 5.61 or higher, you need to replace the chip inside your scanner with the one provided in the TMA box.

•	If you have a ScanMaker IISP scanner, make sure your TMA is of a matching model (TMA for the ScanMaker lISP). If not, call your dealer and exchange the TMA for the correct one. In addition, make sure an external power supply was provided with the TMA in the TMA package, and connect the power supply to the scanner for the TMA to operate properly .

•	If you have a ScanMaker III scanner, make sure the TMA cable is connected on the back of the ScanMaker III scanner and that the screws are very tight. Otherwise, it is possible that the TMA may not work.

•	See #18.


15.  When you launch the ScanWizard Plug-in, the computer crashes with a system error.
15.	The Color Correction button is grayed out and you cannot select it.

Solution:

This button turns gray when the DCR or Dynamic Color Rendition files are missing from the Windows/Twain/Microtek/DCR directory. To fix this problem, run the calibrator program and calibrate your scanner, or reinstall the ScanWizard so that the default profiles are copied onto your system.  A new set of profiles will then be generated.


16.	When you prescan or scan, the scanner will not move an image appears in the software as if the scanner was working.

Solution:

This problem may be due to the scanner selection under the scanner pull-down menu in the Preview window. If you select ScanMaker Demo, the program will go through all the motions of scanning an image, but it will use a sample image file instead of the scanner as the source. To fix this problem, select your scanner model from the Scanner menu. This will change the source from the sample image file to scanner. If no scanner model appears in the Scanner menu, you may have a communication problem with your scanner. See troubleshooting tip #10.


17.	The options billions of colors and 1000s of shades of gray are grayed out.

Solution:

These two options are available only with the ScanMaker III. The option billions of colors is a mode in which you scan 67.8 billion colors, and this requires a 36-bit scanner like the ScanMaker III. The option 1000s of shades of gray is 12-bit (equivalent to 4,096 shades of gray) and is also available only through a 12-bit-per channel scanner like the ScanMaker III. These options can be used only if your application supports them (Photoshop 3.0 does; others may not).


18.	You are not able to select different media types such as negative or positive transparency from the Scan Material command

Solution:

Your Transparent Media Adapter (TMA) may be faulty, or it may not be connected to the scanner properly.

•	If you have a ScanMaker III, make sure the screws on the transparency connector cable are in firmly and screwed tightly to ensure proper connection. If you just plug the cable to the back of the ScanMaker III or simply tighten the screws a little bit, you won't get a good connection.

•	If you have a ScanMaker IISP, make sure the external power supply for the TMA is connected to the scanner. If you did not get an external power supply with your TMA, you have received the wrong TMA. Contact the place where you purchased the TMA for an exchange. For verification, look at the TMA box; it should say "Transparency Adapter for the ScanMaker IISP scanner."


19.	You are unable to use the Auto Document Feeder (ADF)

Solution:

Take note of the following:

•	This problem may occur if your ADF is not properly installed. If you have a ScanMaker IISP scanner, make sure you have the external power supply connected to the back of the scanner. If you did not get an external power supply, contact the place where you purchased the ADF for an exchange. For verification, look at the ADF box; it should say "Auto Document Feeder for the ScanMaker IISP scanner."

•	Also, if you attempt to scan color images through the ADF, you will not able to do so because the ADF only supports multiple page-scanning for line-art, halftone, and grayscale, but not color.

•	Maker sure too that your application supports multiple-page scanning. Some graphics applications can only support one document at a time.


20.	You get the message: "Kodak Precision CMS not found or there is insufficient memory to initialize it.."

Solution:

You may need to reinstall Photoshop and select the Photo CD option (aside from installing the Photoshop program itself and the Plug-ins option, both of which are necessary.)


21.	The KCMS Acquire option is not present.

Solution:

This option is available only in Photoshop, and you will not be able to use it in other image-editing applications.


The Scan Job Window

The Scan Job window is an important feature of the scanning software and provides several key functions in processing your scans.

A scan job is simply a task that you designate the scanner to process and scan. For instance, when you first preview an image, the image as a whole has its own parameters (its own brightness and contrast setting, resolution, etc.). The whole image can be treated as one scan job, or you can select a part of the image, apply different parameters to it, and treat that as a separate scan job. Scan Job 1 can be in color mode, while scan job 2 can be in grayscale mode.

By making the scan jobs distinct, you can then process each job separately (apply image-enhancement, change settings, etc.) and scan them as separate files into your image-editing software (if the software supports multiple open images).

The number of scan job is indicated by the number of titles in the Scan Job window. Scan jobs marked with a check are the ones designated to be scanned, and the jobs are scanned in the order that they appear in the window.

How to read the Scan Job window


Title area

The Title area shows the number of jobs that have been created. In this example, there are two scan jobs. Check marks indicate which job or jobs are to be scanned; the highlighted title indicates the current scan job. To rename a scan job, double click on the title and type over a new name.


The New button

The New button Iets you create a new scan job; the new scan job will have default settings. This feature allows you to create as many scan jobs as you wish, and each scan job can then have its own settings.

How to use the New button


The Duplicate button

The duplicate button lets you duplicate the settings of a scan job. This function is especially helpful if you have created optimal settings for a scan job and wish to use these settings as a template for other scan jobs. This saves time, as you don't have to create the settings repeatedly for every scan job you make

Before using Duplicate, it is helpful to turn on the Smoked Glass Background feature. This will allow you to see clearly the effects of duplication.

To use the Duplicate button


The Save button

The Save button lets you save the settings in a scan job to a scan job template that can be used for future scan jobs.

To use the Save button:

1.	Click on the Save button.

2.	When a dialog box appears, give a name to the scan job template to be saved, then click OK.


The Add button

The Add button lets you add a scan job from a scan job template saved previously.

To use the Add button:

1.	Click on the Add button.

2.	When a dialog box appears, specify the name of the scan job template to be added, then click Add. To close the dialog box, click Close.


The Check button

The Check button allows you to select the scan jobs to be scanned. When you then click on the Scan button to start scanning, the scan jobs marked by a check are the ones that will be scanned. The Check button is a toggle.

To use the Check button:

1.	In the Title area of the Scan Job window, select the scan job to be scanned.

2.	Click on the Check button. A check will appear next to the selected scan job.

3.	To uncheck a selection, select the scan job to be unchecked, and click on the Check button again. The scan job will be unchecked, and the scan job will not be scanned when you click on the Scan button.


The Delete button

The Delete button lets you delete a scan job from the list.

To use the Delete button:

1.	In the Title area of the Scan Job window, select the scan job to be deleted.

2.	Click on the Del button. The scan job is deleted.


The Up/Down Position Arrows

The Up/Down position arrows allow you to change the sequence in which the jobs are scanned through changing the order of the scan jobs in the Title area.

To use the Up/Down position arrows:

1.	In the Title area of the Scan Job window, select the scan job to be moved up or down.

2.	Click on the Up or Down arrow to change the order of the scan job in the list. When you start scanning, the scan jobs will be processed and scanned in the order that they appear in the Scan Job window (i.e., the first scan job is scanned first; the second scan job is scanned, etc.).


The Information Window

The Information window provides information on the cursor and the preview image. It also allows you to change zoom levels directly, in much the same way like using the Magnifying Lens tool in the Preview window.

The Information window is a "floating window" and does not appear when you start up the scanning software. To display the information window, click on the Show Info window command in the View menu (in the Preview window).


Zoom Level Display

The Zoom Level Display magnifies your view of an image, much like the Magnifying Lens tool in the Preview window.

The magnification factor in both Zoom Level Display and the Magnifying Lens tool is by a factor of 2. Thus, the magnification levels increase from 100% to 200%, to 400%, and to the maximum 800%.

To use the Zoom Level Display:

Click on the Zoom Level box. From the drop-down menu that appears, select your zoom or magnification level.


Cursor Locator

The Cursor Locator shows you where the cursor is on the x (horizontal) and y (vertical) coordinates of the axis. This feature is useful for operations that require very precise measurements and alignment.


Color Meter Display

The Color Meter Display is useful if you wish to adjust the shadow and highlight point of an image.

As you pass over a point in the image, the Color Meter Display will show the appropriate RGB values of that point in the image. The significance of the numbers is explained below.

•	The numbers in the Color Meter Display represent color information taken by the scanner. The values can be anywhere from o to 255, with 0 as the black point, 255 as pure white, and all other values in between corresponding to shades from black to white.

•	The values as a whole represent color information for the sample size selected in the Sample Size button. For instance, if you chose 3 x 3 as your sample size and your R value reads 23, that shows your red value of 23 is the average of a 3-pixel area.

Pixel-value information is useful especially if you are making color corrections based on color values. Knowing this, you can modify the shadow and highlight points of an image, then come back to the same point in the image, and verify through the Color Meter Display that the RGB values have indeed changed.

The Color Meter Display can also be used in conjunction with the Color Picker tool.


Sample Size button

The Sample Size button provides options for choosing how extensively the color information will be read whether the color information will apply to a pixel, a 2-pixel by 2-pixel area, or a wider expanse (maximum 5-pixel by 5-pixel area).

When you click on the Sample Size button, the drop-down menu below appears:


Value

If you choose Value, the numbers in the Color Meter Display represent the value in the 0-to-255 pixel scale. For instance, an R value of 23 indicates that the sampling size selected has a red color value of 23. Value is calculated by multiplying the percentage by the constant 255 (value = 255 x percent).


Percent

If you choose Percent, the numbers represent the percentage of the maximum intensity of the pixel. For instance, a G value of 35% indicates that  the sampling size selected has a green color value to be 35 percent intense (out of 100 percent). Percent is calculated by dividing the constant 255 by the value (percent = 255 / value).


Sample Size Options

This determines the expanse of color information to be made available. For instance, if you choose 5 x 5 as your sample area, this means your RGB values will represent color information for a 5-pixel by 5-pixel area. If you choose 1 x 1, the color information pertains to a single pixel -- the one in the middle of the Pixel Display.


The Pixel Display

The Pixel Display helps you see how color pixels are organized and distributed. The display can then help you make an informed judgment on how best to modify image characteristics such as shadows and highlights, and also allow you to verify any changes that are made.


The Preview Window

The Preview window is the most prominent window of the four major windows, and it includes the various commands and tools for controlling the scanner.


The Menu Bar

The Menu bar includes the different menus for setting up the scanner (Scanner menu), controlling view options (View menu), customizing the software (Preferences menu), and accessing onlne help (Help menu).


The Scanner Menu

The Scanner Menu lets you:

•	Show your scanner model or select the current scanner if you have multiple scanners

•	Get information about your scanner

•	Get information about the SCSI chain


Scan Model

The top of the scanner menu displays the scanner model you're using together with its SCSI ID. If you have multiple scanners on your system, all the scanners are shown with their respective SCSI IDs, and the current scanner is indicated by a check.

Only one scanner can be accessed at a time. To switch among various scanners, select the scanner to be used.


Get Current Scanner Info

This command provides information about your current scanner and displays a dialog box that shows the scanner model, SCSI ID number, and firmware version.


Get SCSI Chain Info

This command allows you to see the SCSI devices on your SCSI chain, particularly your scanner, as well the SCSI ID number of the devices.

By default, all numbers are selected by the check boxes. To allow ScanWizard for Windows to start up more quickly, select only the boxes that match the SCSI ID of your scanner (or scanners, if you have multiple scanners on your system). This will make the ScanWizard bypass the numbers for your other devices and focus effort on simply detecting scanners. If you're not sure about which numbers to specify, check all the boxes.

To use the SCSI Check feature:

1.	Choose the Get SCSI Chain command. The SCSI Check dialog box will appear.

2.	If your scanner does not show, click on the Probe button. Make sure your scanner is connected and turned on before clicking on the Probe button.

3.	Make sure the correct interface cad is shown in the card selection box. If not, choose the correct interface card.

4.	Check the numbered box corresponding to your scanner (or scanners).


Exiting ScanWizard

To exit Scan Wizard for Windows, double click on the close box on the upper left side of the Preview window.


The View Menu

The View menu lets you:

•	Get a full page preview of an image

•	Get a zoomed-in (enlarged) view of an image

•	Resize the preview window

•	Show or hide the Settings, Information, and Scan Job windows


Full Page Preview

This command shows one of the two viewing modes available for your image (the other being the zoomed preview).

The full page preview is a preview of your image as defined by the parameters set in the Preview Setup command (in the Preferences menu). For instance, if your image is 8" x 5" but the dimensions in the Preview Setup are 4" x 3", your full page preview will be 4" x 3".

The maximum size of the full page preview varies, depending on your scanner model. For example, if the scan bed (the glass surface) of your scanner has a maximum size of 8.5" x 11", the maximum full page preview will be limited to those dimensions.

The size of the full page preview can be changed by setting new dimensions in the Preview Setup command. The new dimensions will take effect, however, only after you click on the Preview button so that the scanner does a new preview; only then will you see the new dimensions of the full page preview.

You may wish to change the size of your full page preview to improve performance and save memory. A smaller preview area will occupy less memory, speed up processing, and yield a higher -resolution preview. This is because ScanWizard takes your preview image and calculates dynamically how best to display that image in the smaller preview area  resulting in a higher-resolution view.

How to use Full Page Preview


Zoomed Preview

This command displays the magnified view of your image when you use the Zoom Preview tool.

The zoomed preview is the view of a specific part of the image shown in higher resolution with more visible detail. If you have zoomed preview enabled, the view is stored in memory, and you can easily switch between full page preview and zoomed preview.

The zoomed preview is different from the zoomed-in view obtained from the Magnifying Lens tool. The zoomed-in view is simply an enlarged view, but it is not in high resolution.

How to use Zoomed Preview


Resize Window to Fit

This command adjusts the Preview window to fit the preview area.

Sometimes, the preview window is larger than the preview area, as denoted by an empty space below the vertical ruler. In other instances, the preview window may also exceed the preview area if you manually enlarged the preview window (by dragging on the Windows resize box).  To utilize window space more efficiently, use this command to resize the preview window.

How to use Resize Window to Fit


Show / Hide commands

These commands allow you to switch between showing or hiding the Settings, Scan Job and Information windows on your screen. The commands also have their tool-button counterparts in the form of three arrowheads onthe right edge of the toolbar.

How to use Show / Hide commands


The Help Menu

The Help menu lets you access online help for the ScanWizard

The Help menu users standard Windows conventions for obtaining online help. If you're not familiar with this procedure, refer to your Microsoft Windows user's guide

•	About


About

This command gives you information on the ScanWizard for Windows scanning software, which is referred to in the About screen as the ScanWizard scanner controller.


The Preferences Menu

The Preferences Menu lets you

•	Choose the correct scan material

•	Create effects like invert

•	Create effects like mirror

•	Create cursor lines to help you with alignment

•	Control the size of your Preview window

•	Create a smoked glass background to help distinguish the current scan frame

•	Set other options, such as specifying a working directory for files


Scan Material

This command allows you to select the correct scan  material. Scan materials can be generally classified into three types:

•	Reflectives, such as photographs or prints.

•	Positives, such as slides.

•	Negatives, such as the negative film you use for your camera

The default scan material selection depends upon the scanner you're using, and the choices available to you will also depend on your equipment.

The positive option, for instance appears only if you're using a Transparent Media Adapter (TMA) with your scanner. The negative option appears only if you have DCR installed and are using the TMA to scan a negative. If you are scanning negatives or positives, make sure you specify the correct scan material type, or you will get inaccurate scanning results.

How to use Scan Material


Invert

This command creates a negative of an image. The Invert effect is applied to the whole preview image; it cannot be used for only a specific portion of the image.

When an image is inverted, the brightness value of each pixel is converted to the inverse value on the 256-step color values scale. For example, a pixel in positive image with a value of 255 is changed to 0, and a pixel with a value of 5 is changed to 250.


Horizontal Mirror

This command allows you to flip the image so that a mirror effect is created. The Mirror effect is applied to the whole preview image; it cannot be used for only a specific portion of the image.

When the mirror image appears, the scan frame will still be in the old location, and you will need to move the scan frame if you wish to define another area.


Cursor Auxiliary Lines

This command allows you to create horizontal and vertical grid lines with your cursor to help define a scan frame precisely. Using the grid lines, you can read the measurements off your ruler more easily.

How to use Cursor Auxiliary Lines


Preview Setup

This command allows you to set the dimensions for your Preview area. To use a particular option, click on the box before the option. A check will appear in it to indicate that the option is enabled.

Click on the topic for information.

How to set the preview area


Live Preview

If this option is checked, the ScanWizard Plug-in will immediately show changes that you make to the preview image. You can turn off Live Preview if you're previewing or scanning only in grayscale; this will speed up the process.

If Live Preview is on:

•	Changes you make to the preview image are shown instantly (for example, switching from color to grayscale)

•	If you're scanning in grayscale and live preview is on, the image appears in color unless you specifically change image type in the Type box (in the Settings window) to a grayscale mode. This happens because Live Preview always does previews in color.

If Live Preview is off:

Your preview will be in accordance with your image type (i.e. if you have a grayscale image, your preview is in grayscale; with a color image, you get a color preview). If you apply any image-enhancement control, the changes will not be apparent until you do a new preview (click on the Preview button again).

Live Preview applies only to color scanners. If it is enabled, the next option, Color Preview, will be dimmed.


Color Preview

Color Preview is for color image type only.

This option applies only to three-pass color scanners, and is enabled only if Live Preview is not selected. If this option is turned on, the image will be scanned in whatever scan mode is specified in the Type box (in the Settings window). If it is turned off, the image will be scanned in grayscale.


Fast Preview

This option allows you to choose your preview mode. If Fast Preview  is on, the preview process is faster, but the quality of the preview image is a little coarse. If Fast Preview is off, the preview process is slower, but the quality of the preview image is improved.

The Fast Preview option is a hardware-related feature and may or may not be available, depending on your scanner model.


The Preview Area

The Preview Area lets you select the size of your preview area, and includes the following options: Letter, A4, legal, maximum size, or custom size.

•	Maximum refers to the maximum scan area that can be supported by your particular scanner model.

•	Custom will appear if you type in your own specifications and changes any of the edit boxes.

•	The Top, Left, Width and Height edit boxes allow you to specify the dimensions of the preview area. Top an Left refer to the starting points of the preview area on the x and y coordinates. Width is the expanse of the preview area, and Height is the depth of the preview area.

•	The unit of measurement, indicated to the right side of the Top box, is the unit selected in the Settings window.


Keep Preview Image

This command allows you to keep the preview image in the preview window even after you exit ScanWizard for Windows. This way, the previous preview image still comes up the next time you bring up the software. This command allows you to retain the last preview image you used; the preview image is kept in the preview window after you exit ScanWizard.

The next time you start up ScanWizard, this last preview image is again displayed in the preview window.

To use this feature:

Choose the Keep Preview Image command in the Preferences menu. A check appears next to the command when it is enabled.


Smoked Glass Background

This command helps you distinguish the current scan frame from the rest of the material for greater visibility of the current scan frame.

With the Smoked Glass feature turned on, the part of the image within the current scan frame will stand out, while the rest of the image (the "irrelevant" material) is relegated to a background resembling smoked glass.

If you have multiple scan frames, only the current scan frame stands out, and the inactive scan frames are hidden behind the smoked glass screen.

The Smoked Glass Background, then, helps you focus on the part of the image within the current scan frame, and is particularly helpful when you are editing a scan frame or applying image-enhancement controls. This way, the changes can be seen more clearly and stand out from the rest of the material. (See the next section for more details. )

To use this feature:

Choose the Smoked Glass Background command in the Preferences menu. A check appears next to the command when it is enabled.

For accurate results, make sure you enable the Live Preview option (in the Preview Setup command, in the Preferences menu).


More

This command allows you to specify a working directory where you can save all temporary and data files, including files for job templates.

To use this feature:

1.	Choose the More command in the Preferences menu. The dialog box  appears.

2.	Click and hold down the Working Directory box, and from the pop-up menu that appears, choose your working directory.

3.	If you click on the folder icon, the Directory Browser dialog box appears. Choose your  working directory, then click OK to close this dialog box.

Whatever directory you specify is automatically added to the pop-up menu above for you to choose from in the future. If the directory you specify is not found or does not exist, a warning message appears, and the current directory of the ScanWizard for Windows  is used instead.

4.	When you have completed your choices, click OK to close the More Preferences dialog box. For the changes to take effect, exit ScanWizard, then relaunch the program.


The Tool Buttons

The Tool buttons simplify the performance of certain tasks. The Tool buttons are (left to right) Zoom Preview, Scan Framel, Magnifying Glass, Hand, and Color Picker.


 Zoom Preview tool

The Zoom Preview tool gives you the zoomed preview, which is an enlarged, high-resolution view of an image with more visible detail.

The zoomed preview is different from the zoomed-in view, which is obtained by using the Magnifying Lens tool and is not a high-resolution view. By using the Zoom Preview tool and creating the zoomed preview, you can then switch easily between full page preview and zoomed preview.

How to use the Zoom Preview tool


 Scan Frame tool

The Scan Frame tool lets you create or modify a scan frame, which is the active area on which controls and commands can be applied. You can have multiple scan frames, but only one can be current at a time; the current scan frame is indicated by a marquee (marching ants). The current scan frame can be more easily distinguished if you turn on the Smoked Glass Background command (in the Preferences menu).

How to use the Scan Frame tool


 Magnifying Lens tool

The Magnifying Lens tool enlarges your view of the preview image, allowing you to set the scan frame with greater precision if you need to. Only your view of the image is changed; the actual size of the image remains unaffected.

Each click magnifies or reduces by a factor of 2. Thus, the magnification levels increase from 100% to 200%, to 400%, and to the maximum 800%.

If the portion that you want to magnify includes most of the preview area, the Lens tool will magnify the view only slightly. To solve this, enlarge the size of the preview area (through the Preview Setup command), or create a smaller selection area.

How to use the Magnifying Lens tool


 Hand tool

The Hand tool lets you scroll through a preview image, allowing you to move parts of the image into view. The Hand tool can be used for zoomed-in images (enlarged through the Magnifying Lens tool), or images not included completely within the frame of the preview window (for instance, if your preview image is 8 inches wide and you resized the width of your preview window to only 5 inches).

How to use the Hand tool


 Color Picker tool

The Color Picker tool allows you to sample color from an area of an image and to designate a new shadow or highlight point.

With the Color Picker tool, you can determine the color values for any pixel in an image. When you click on the Color Picker tool and pass over a pixel, the value of that pixel will be displayed in the Information window, based on the sample size also selected in the Information window. Pixel-value information is useful especially when you're making color adjustments based on color values.

The Action buttons

The Action Buttons generate a specific action from the scanning software. The Action buttons include Preview and Scan.


Preview button

The Preview button gives you a preliminary view of the image on your scanner bed.

Previewing an image gives you greater flexibility, as it allows you to apply various controls to the preview image before actually scanning it in. With the preview image displayed, you can apply image enhancements or crop the image before performing the final scan.


Scan button

The Scan button lets you scan in the image in your scanner and delivers it to your image-editing software. The scanned image is based on the specifications you have chosen in the Settings window and on controls you may have applied to the preview image if a preview was performed.


Rulers

The rulers on both sides of the preview window help you with operations that need precise measurement and alignment of your image.

The unit of measurement in the rulers is determined by the unit of measurement you have selected. This can be done either in the Image Dimension controls, located in the Settings window, or by clicking on the ruler unit button at the 0,0 point of the rulers in the Preview window.

Depending on your chosen unit of measurement, the rulers can mark off measurement in these units: inch, centimeter, millimeter, point, and pixel. The pixel option is dimmed if the selected resolution unit is lpi.

To select the unit of measurement for rulers:

Click on the unit box in the Settings window, or click on the ruler unit button at the 0,0 point of the rulers in the Preview window. When the submenu appears, select the unit of measurement.


Preview Area

The preview area is where the preview image appears.

The size of the preview area varies, depending on your scanner model. The size can be changed, however, through the Preview Setup command in the Preferences menu. You can increase the size of the preview area to see more detail in your image, or you can reduce the preview area to save on memory.

For details on how to change the size of the preview area, refer to the Preview Setup command in the Preferences menu section.


Scan Material Status icon

Another way to access the Scan Material menu is to use the Scan Material Status icon, located to the right of the Scan Button.

The Scan Material Status icon is related to the use of the Transparent Media Adapter (TMA) for scanning slides and filmstrips with your scanner. With the TMA in use, the appearance of the icon will change, depending on whether your scan material is a reflective photo or print, or whether it is a positive or negative transparency /filmstrip.

•	If you're scanning a reflective (such as a photo or print), or if you're not using the TMA, this icon will appear in its normal form like ordinary icon. When you click on the icon and hold down the mouse, you will see the Reflective option checked.

•	If you're scanning a positive transparency or filmstrip, this icon will appear in the form of a positive. When you click on the icon and hold down the mouse, you'll see the Positive Transparency option checked.

•	If you're scanning a negative transparency or filmstrip, this icon will appear in the form of a negative. When you click on the icon and hold down the mouse, you'll see the Negative Film option checked.


  Show / Hide Window buttons

These buttons allow you to show or hide the Settings, Scan job and Information windows on your screen.

To use this feature:

Click on a button for viewing a window. When the window appears, you can click on the button again to hide it


Unit of Measurement button

The unit of measurement allows you to select your unit of measure. The options include inch, centimeter (cm), millimeter (mm), point, and pixel.


The Settings Window

The Settings window contains the commands for outputting your scanned image and includes the image-enhancement tools of the program.


Output Image Parameters

The Output Image Parameters include the various controls that determine how your image is scanned and processed.

The Output Image parameters include:

•	Type

•	Resolution

•	Resolution Unit Selectiom

•	Image Dimension controls


Type (Image Type or Scan Mode)

The Type menu determines what your resulting scan will be. It does not refer to the original image mode. For instance, if you have a color photo but choose 256 grayscale for the scan mode, the photo is scanned and processed as grayscale.

The options available in the Type menu will depend on the type of scanner you have. For example, if you have a 36-bit scanner, the option Billions of colors will be active. If you only have a grayscale scanner, the options relating to color will be dimmed.

How to use the Type


Resolution

Resolution in the Settings window refers to the desired resolution for outputting the image to a device, such as a monitor or printer. It does not refer to the resolution in which the image is scanned. The maximum output resolution is dynamically calculated by the system as determined by the maximum scanner resolution and the scaling setting.

Resolution is also related to scaling, or how large or small the image will be scanned relative to the original. When you change resolution, the scaling may be affected slightly if the resolution you selected has no exact equivalent in scaling.

To set your resolution:

Enter a resolution setting in the Resolution edit box. There is no need to press the Enter key; typing in a value automatically inputs it into the system. If the value you enter is too low or too high, the minimum or maximum resolution value is entered for you instead.

Note:  In setting resolution, choose the setting that best matches your output device. Remember that the higher the resolution, the larger the resulting file will be and the longer it will take to output.


Unit Selection
Resolution Unit Selection

The unit of measurement for resolution is in dpi (dots per inch) and lpi (lines per inch) Lpi settings are dimmed if the ruler unit is in pixels.

To select your unit option:

•	Choose dpi if you know precisely the resolution you need for your image. For more details on resolution, see the Basic Concepts chapter in the manual.

•	Choose lpi Draft to produce resolution that is one times the screen frequency (no higher than 72 pixels per inch). Draft quality may result in output images that look a little blurred or indistinct at edges.

•	Choose lpi Medium to produce resolution that is one and one-help times the screen frequency.

•	Choose lpi Final to produce resolution that is two times the screen frequency.


Image Dimension controls

These controls allow you to adjust the various factors that affect the image, including the width and height for your image when it is first scanned (input), the scaling factor, and the dimensions of the image when it is finally output.


Mathematical Formula

This is a mathematical formula expressing the relation of the input dimensions to scaling and how they affect the dimensions when the image is scanned.

•	Input width and input height refer to the dimensions of the scan frame that you draw. For example, if the image on your scanner is 5" x 7" and you draw a scan frame that is 3" x 4", then your input width will show 3.000 and your input height will show 4.000.

•	Output width and output height refer to the dimensions of the image when output to an output device (such as a monitor or printer).

The input width, input height, output width, output height are affected by your scaling and whether or not the Aspect Lock is on.

How to use the Input-Output demensions

How to use the Aspect Lock

How to use Scaling


Aspect Lock

The Aspect Lock allows you to keep the ratio of the image width and height constant.

How to use the Aspect Lock


Scaling control

The Scaling control lets you create large or small images so that the images don't have to be resized subsequently, which is usually done in your image-editing software.

How to use Scaling


Unit of Measurement

The Unit of Measurement allows you to select you unit of measure. The options include inch, centimeter (cm), millimeter (mm), point, and pixel.


Size

The Size indicates how big the file will be when you accept the dimensions shown in the edit boxes, together with the resolution setting that you selected. Size is calculated automatically.


Image Adjustment controls

The image adjustment controls include the Auto button and the Color Correction button, located below the Image Status Controls.

•	Auto

•	Color Correction (DCR)


Auto (Automatic Contrast Control)

The Auto button optimizes the contrast of scanned images by making adjustments to the  Shadow/Midtone/Highlight values. The Auto button will be dimmed if the image type selected in the Type box is line art or halftone.

How to use the Auto control


Color Correction (DCR)

This tool applies a generic color correction profile to your images to give it accurate, lifelike color. By default, the Color Correction feature is turned on. If you have Microtek's  DCR color calibration and correction system installed, the Color Correction button will override the generic color profile and apply DCR to the image.

A generic color profile is provided with the scanning software to correct the minor color shifts that occur invariably with scanners. To achieve optimal color correction, however, you need a true color calibration and correction system like Microtek's DCR, or Dynamic Color Rendition, developed expressly for this purpose.

DCR creates an industry-standard color profile matched to your scanner, so that colors in your scanned image are adjusted to their optimal levels. DCR comes standard on certain ScanMaker models and is available as an option on other models.

The Color Correction button is turned on by default, but it can be turned off by clicking on the button again. Color Correction will be dimmed in the following instances:

•	If image type in the Settings window is set to billions of colors, any grayscale setting, line art, or halftone.

•	If the scan material type chosen (in the Scan Material command, Preferences menu) is Negative.

How to use the Microtek Calibrator


Image-Enhancement Tools
Image Enhancement Tools

The Image- enhancement tools provide you with various tools for adjusting your image.

•	Brightness, Contrast, and Exposure

•	Tints

•	Shadows and Highlights

•	Curve

•	Filters

•	More Options


Brightness, Contrast and Exposure tool

The Brightness, Contrast and Exposure (BCE) tool changes the brightness, contrast and exposure setting of the entire image.

Brightness is the balance of light and dark shades in an image, while contrast is the range between the darkest and lightest shades in the image. On the other hand, exposure works like the exposure feature in photography, allowing you to change exposure of the image by increasing for reducing available light to the image. The Exposure control is a scanner hardware-related feature, and using it correctly can allow more detail to emerge in an image, especially if it was underexposed.

The goal in using the BCE tool is to get the fullest dynamic range possible for your image. Because the BCE tool affects the image as a whole, you can try using the Shadows and Highlights tool instead to get the effects you want if you find that BCE tool alters your image too much.

How to use the BCE tool


Contrast Control

The Contrast control lets you change the contrast setting.

•	High contrast can make an image look like a photocopy of a picture with little or no gray shades.

•	Low contrast can make an image look dull and flat.


Brightness Control

The Brightness control lets you change the brightness setting.

•	Too much brightness can make an image look washed out.

•	Very low brightness levels can make an image look very dark.


Channel Control

The channel control lets you change exposure settings for a particular color channel (red, green or blue).


Exposure Control

The Exposure control lets you increase or reduce available light to the image, This can be used to allow more detail to emerge in an image, especially if it was underexposed.

•	More exposure can result in lighter images with more visible detail. The higher the exposure, the longer it takes to scan the image.

•	Less exposure can make an image dark and without detail.


The Action Button in the AIE dialog box

Click on an action button to achieve a particular effect. The Action button in the AIE dialog box carry out a specific action.

The OK button

Clicking on this button will apply whatever image enhancements you have performed on the current scan job, and close the AIE dialog box. Clicking OK is not the same as switching to another scan job (if you have multiple scan jobs). If you switch scan jobs, the effects are applied to your current scan job, and then the new scan job shows up; you do not exit the AIE dialog box.

The Cancel button

Clicking on this button will cancel out all image-enhancement changes you have made to the current scan job, and then close the AIE dialog box.

The Reset button

Clicking on this button brings up the Reset dialog box, where you can specify which settings are to be reset, then click Reset or Cancel. If Reset is selected, the settings are restored to their default values; if Cancel is selected, the operation has no effect.

The Revert button

Clicking on this button cancels out the changes you made with the current image-enhancement tool. This means that if you used several tools (and achieved a look that is the cumulative effect of all the tools), using Revert will cancel the effect of only the current tool and preserve the effects of the other preceding tools.


Choose your scan job here

This is where you select the scan job to which image enhancement will be applied. (Note: For definition of a scan job, see the Scan Job section of the Reference). If you have multiple scan jobs, you can switch among the various jobs, and the thumbnails will change accordingly to show the selected scan job.

Important

Switching to a new scan job while using the AIE dialog box will make any changes to the currently selected scan job permanent. This cannot be undone even by selecting the Cancel button.


Left thumbnail: Before enhancements

This is the thumbnail of the image captured by your scanner. The left thumbnail is the "before" version -- which shows the effects of the last saved settings values.


Right thumbnail: After enhancements

This is the thumbnail of the image captured by your scanner. The right thumbnail is the "after" version -- which shows the effects of the new settings added in the AIE.


Image-Enhancement Tools

To select another image-enhancement tool, click on any of the buttons displayed in the vertical toolbar on the right side of the dialog box.


The Tints tool

The Tints tool adjusts the hue or saturation of colors. This tool applies only to color images and is not available for use with grayscale or black-and-white images.

Hue is the aspect of color that distinguishes one color from another (whether it is red, green or blue). In the RGB color mode, hue can be distinguished by its position in the color wheel.

Saturation, on the other hand, refers to the intensity of color (more red in an apple, more green in the grass). Increasing saturation can have a dramatic effect on the colors of an image, but beware of increasing saturation too much, as it creates artificial-looking, overly bright colors.

The Tints tool is useful when your image has a particular color cast and you wish to remove the cast to make the image look more natural. The Tins tool is also related to the Scan Material command in the Preferences menu. For reflectives or positives, the Tints tool lets you adjust hue and saturation. For negatives, the Tints tool provides additional controls for selecting film type and adjusting exposure.

How to use the Tints tool


Color Wheel

The Color Wheel shows you the position of colors: green is across magenta, and red is across cyan. By moving the pointer (a small dot) to a place in the color wheel, the hue of the image is altered. For instance, if you move the pointer towards the green area of the wheel, the image will acquire a greenish cast.


Saturation bar

The Saturation bar lets you change the intensity of the hues (colors) in your image. Use Saturation selectively, because increasing saturation will intensiify all hues in the image.


Film Type Selection bar

The Film Type Selection bar allows you to select the type of film you used for your negative. Choosing the correct film type is important for maintaining image quality, and you should choose the film type that's indicated on the packaging that came with your film.

The Film Type Selection box provides several choices for you to choose from. If your type of film is not in the list but a similar film type from the same company is available, you may choose from one of them. Very often, similar films from the same company use identical film types. For example, Kodak 135, ASA 100, ASA 200, and ASA 400 are grouped as the same type  ASA 100.

If your film type is not in the selection list and you cannot find its family group, choose Generic Negative Film.


Exposure Correction bar

The Exposure Correction bar lets you  adjust the exposure of a negative. An overexposed negative looks dark (with the image itself in the dialog box appearing bright), while an underexposed negative appears light (with the image itself appearing dark).

•	If your film is overexposed (image is too bright), drag the bar to the left; this will make the image darker.

•	If your film is underexposed (image is too dark), drag to the bar to the right; this will make the image lighter.


The Shadows and Highlights tool

The Shadows and Highlights tool lets you change the shadow and highlight point of an image.

By using this tool, you can manipulate shades so that the Shadow point becomes the new darkest value and the Highlight point becomes the new lightest value. Shades that are darker than the shadow then become black, and shades lighter than the highlight become white. For example, if you set the highlight point to 200, all points in the image with a value greater than 200 will be a mapped to value of 255, since 255 represents the "whitest" white.

The Shadows and Highlights tool can be used for both grayscale and color images. If you have a limited range of grays between your lightest and darkest point, using shadow and highlight will have the effect of extending the range of grays and make more detail in the image visible. This tool is not available for use with line art or halftone scan modes.

How to read and correct a histogram

How to use the Shadows and Highlights tool


Histogram

The Histogram is a graphic representation of how all the pixels in an image are distributed across brightness and darkness levels. The darkest pixels are at the left; the lightest pixels are at the right.

•	A histogram skewed heavily to the left indicates that the image has many more dark pixels than light.

•	A histogram skewed heavily to the right will indicate a light image as it has more light pixels than dark.

•	The height of the histogram indicates the number of pixels at that point in the histogram.


Triangles

The Triangles (indicators) below the histogram adjust the Shadow, Midtone, and Highlight settings.

•	The black triangle (left) controls the shadows. Moving this triangle to the right will emphasize shadows and create a darker image.

•	The gray triangle (middle) controls the midtones and indicates how the brightness and darkness pixels are divided. Moving it to a value less than 1.0 will have the effect of darkening the image. Moving it to a value greater than 1.0 will have the effect of lightening the image.

•	The white triangle (right) controls the highlights. Moving this triangle to the left will emphasize highlights and create a lighter image.

Note: The gray and white triangles will change in color if a color channel (not Master) is selected in the Channel box.


Histogram bar

The Histogram bar shows the distribution of shades from dark to light (left to right). The distribution of shades changes as you move any of the triangles.


Input edit boxes

The input edit boxes show how pixels are distributed over the 0-to-255 pixel scale.

The input values are related to the position of the indicators along the histogram. For example, if you move the left triangle in from 0 to 30, the input range becomes 30 to 255, and pixels in the range of 0 to 30 are then set to 0. In a process called mapping, the new range (30 to 255) is stretched back to become 0 to 255. The image then becomes darker, since all pixels from 0 to 30 are now mapped to black (whereas 0 to 30 before had subtle gradations from black that lightened up gradually).

The same principle applies when you move in the right triangle, and the highlights in the image become more pronounced.

Moving in any of the triangles above the input boxes will change the values in the edit boxes. You can observe how the values in the boxes are affected by moving the triangles, or you can enter values into the boxes directly. In both cases, the histogram will change accordingly.


Out edit boxes
Output edit boxes

The Output edit boxes show the 0-to-255 pixel range to where the Input levels are mapped. For example, if you modified the input values to 30 and 255 and then change output values to 0 to 250, the input values of 30 to 255 will be "stretched" to fit the output range of 0 to 250. This means you have a total of 250 shades (250-0=250).

Unless you have very specific effects in mind, it is better to leave this feature alone, so everything is always mapped to 255 shadows (255-0). You can experiment with this feature to see what it does, however, and how it interacts with the input levels.


Original / Enhanced box

The Original / Enhanced box lets you choose which histogram to see: the original, before the image was modified; or enhanced, after the image had been modified (with shadows and highlights or any other tool).


Channel button

The Channel button lets you control the Shadow and Highlight settings for a particular color channel (red, green or blue) or for the Master channel (red, green, and blue simultaneously).


Input / Count / Percent

The Input / Count / Percent figures provide information about the histogram. The figures will appear only when the cursor is inside the histogram or if a triangle is being moved.

•	Input value indicates the color value of the data displayed in the histogram.

•	Count value indicates the number of pixels at the Input value. If Input value is 2 and Count value is 1300, then there are 1300 pixels in the image at the input value of 2.

•	Percent value is the percentage of all pixels in the image where color value is less than or equal to the input value. If Percent is 15% and Input value is 2, it means that 15% of all pixels in the image have a value of 2 or less.


The Curve tool

The Curve tool lets you control the gamma, which measures the intensity affecting the mid-level grays (midtones) of an image. Adjusting the gamma lets you change the values of the middle range of gray tones without dramatically altering the shadows and highlights.

In many ways, the Curve tool gives you the most control for adjusting an image's values, but novice users may take some time to master its intricacies. The Curve tool applies to grayscale and color images and is not available for use with line art or halftone scan modes.

How to read the curve

How to use the Curve tool


Curve

The Curve is a graphic representation of the gamma showing scanner input from dark on the left to light on the right.


Method

The Method option sets the kind of curve you wish to have. Select from Line, Curve or Gamma.


Channel

The Channel option allows you to choose the color or gray channel in which the gamma will be affected.


Curve buttons

The Curve buttons let you modify the curve. The tools are the pointer, zoom frame, and hand.

How to use the Curve buttons


Pointer button

Use the Pointer button to define points in the curve that will be modified. When you click on any point in the curve, a control point will appear to mark your position. To remove a control point, drag it off the graph.


Zoom Frame button

Use the Zoom Frame button to zoom in on a particular point in the curve. Once the area is zoomed in, you can then use the pointer tool to define new points for more precision. This is particularly useful for working with 12-bit images, as more detail can be seen in such images. The zoom level can be seen in the Zoom column. To zoom out, hold down the Shift key and click on the mouse simultaneously.


Hand button

Use the Hand button to scroll through the curve if the curve has been zoomed in. The Hand tool can be used only if the curve has been zoomed in with the Zoom Frame button (above). Otherwise, the Hand tool will be dimmed.


Save button

The Save button allows you to save the curve. To do this, click on the Save button and specify a file name for the curve to be saved.


Load button

The Load button allows you to use a previously saved gamma curve for another image. To do this, click on the Load button, then specify the curve to be loaded.


The Filters tool

The Filters tool lets you apply or create special effects to your images. This tool is disabled when your image type is set to billions of colors, 1,000 shades of gray (grayscale), line art, and halftone.

How to use the Filters tool


Show Filter Effect on Preview Image

To preview filters and see their effects immediately, click on this box.


Filters

The filters include:

•	Blur and Blur More

•	Sharpen and Sharpen More

•	Edge Enhancement

•	Emboss

•	Unsharp Masking


Blur filters

The Blur filters eliminate noise in the parts of the image where significant color transitions occur. The Blur filters decrease the contrast between adjacent pixels, making the image appear hazy and out of focus.

•	Blur smoothes out the transitions by lightening pixels next to the hard edges of defined lines and shaded areas.

•	Blur More produces an effect three or four times stronger than Blur.


Sharpen filters

The Sharpen filters do the opposite of the Blur filters and increase the contrast of adjacent pixels, making images appear sharper and more focused.

Both Sharpen and Sharpen More filters improve clarity. The Sharpen More filter has a stronger sharpening effect than the Sharpen filter.


Edge Enhancement filter

The Edge Enhancement filter give greater contrast to edges. The filters can do this because edges are usually areas in an image where gray or color levels change abruptly.


Emboss filter

The Emboss filter makes a selection appear raised or stamped by suppressing the color within the selection and then tracing its edges with black.


Unsharp Masking

The Unsharp Masking filter adjusts the contrast of edge detail and creates the illusion of more image sharpness. This filter can be useful for refocusing an image that has become blurry from interpolation or scanning.


The More Options tool

The More Options tool provides you with additional scanner and image controls. These controls include:

•	Descreen

•	Velocity

•	Gray Scan CCD Filter

•	Using the linear gamma curve

To use the controls in the More Options tool:

Click on the More Options tool in the Settings window. When the More Options screen appears, select the particular control to be modified and its option, then click OK.


Descreen

Descreen allows you to remove moiré patterns in images.

A moiré is an undesirable pattern in printing that results from incorrect screen angles of overprinting halftones. Moirés usually result when you scan images taken directly from a magazine (instead of scanning a continuous glossy photographic original or a transparency).

How to use Descreen


Velocity

The Velocity command adjusts the speed with which the scanner moves during scanning.

As the scanner processes the image and sends it to the computer, the scanner is also getting more information continuously from the moving scanner mechanism. If the computer cannot store the image data as fast as the scanner sends it, the scanner mechanism has to stop while the scanner waits for the computer to catch up. These brief pauses during scanning sometime cause the quality of the scan to go down, and images then appear with blurs or lines running across them. It is important, then, to select a slower scanning speed.

Slower scanning speeds give better image quality, but Auto is the recommended setting, as it provides the best balance between speed and image quality. If your images appear to have velocity-related problems, try lowering your velocity, and experiment with different settings until you find the fastest velocity at which the images are in good quality and appear to have no lines in them.

How to use Velocity


Scan Quality

This control allows you to specify the quality of your scan in relation to your scanning speed.

•	If Draft is selected, the scanning speed is faster but image quality is not as good as when Final is selected. Draft is the default option.

•	If Final is selected, image quality is better than Draft, but scanning speed is a little slower.


Gray Scan CDD Filter

This option allows you to select a particular color channel when scanning grayscale images and is useful for obtaining certain effects. When scanning grayscale images, one of the color channels of the CCD is usually used for scanning; this can be the red, green or blue color channel.


Use Linear Gamma Curve

This control allows the scanning software to read only raw image data, so that no color adjustment (not even the generic color correction profile) is applied to your image when it is scanned.

This control is helpful for professional graphic designers who wish to create very specific effects and are thoroughly familiar with the scanning process. If you are not familiar with this feature, leave this option turned off.


The Window Expansion button

The Window Expansion button lets you expand the Settings window to its full size, with the bottom half of the window revealing the image-enhancement controls.

When the bottom half of the Settings window is open, you can use the image-enhancement functions directly by dragging on the slide bar for each control. This is like clicking on the image-enhancement tool, which takes you to the Advanced Image Enhancer (AIE) dialog box where you can change the controls.

Using the slide bars to adjust images may be faster, but using the image-enhancement tools gives you greater control over adjusting images and shows you "before-and-after" images in the AIE dialog box.

To close the bottom half of the window, click on the Window Expansion button again.
