Making a Correction with the Color Match Control


Color Match control
To make a correction using the Color Match control:
1.  In the Color Correction tool, click the tab that includes the Color Match control with which you want to work.
For help, see Entering and Exiting Color Correction Mode.
2.  (Option) If necessary, select either of the following options in the Correction Mode Settings dialog box:
  Eyedropper 3 x 3 Averaging
When you select "Eyedropper 3 x 3 Averaging," the system calculates the color value to pick by averaging the values of a 3 x 3 sample of pixels centered on the eyedropper's position. This is often useful for picking up a color accurately by sight because it compensates for shifts in color value from one pixel to another. When this option is deselected, the system selects the color value of the exact pixel at the eyedropper's position.
  Eyedropper Picks from Anywhere in Application
When you select "Eyedropper Picks from Anywhere in Application," you can pick colors from anywhere in the application using the Color Match eyedroppers. For example, you can pick a target color for a Color Match correction, such as a desirable skin tone, from the swatch that appears beside a custom color saved in a bin or from one of the ChromaWheels.
For complete information on the Correction Mode Settings dialog box, see Customizing Color Correction Mode Settings.
3.  Select the input color (the color to be replaced):
a.  Move the pointer over the input color swatch.
b.  Press and hold the mouse button, and then drag the eyedropper to the area of the image in the monitor from which you want to select an input value.
c.  Release the mouse button to complete the selection.
  If the "Eyedropper Picks from Anywhere in Application" option is selected in the Correction Mode Settings dialog box, you can select an input color from another location in your Avid application using the eyedropper. Also, you can pick from the Windows Color dialog box or the Macintosh Color Picker by double-clicking the input color swatch. However, you will usually want to select your input color from the current segment.
4.  Select the output color:
a.  Move the pointer over the output color swatch.
b.  Press and hold the mouse button, and then drag the eyedropper to the area of the image in the monitor from which you want to select an output value.
c.  Release the mouse button to complete the selection.
  Your output color will usually be selected from an image other than the current segment, such as the next segment or a reference frame. If the "Eyedropper Picks from Anywhere in Application" option is selected in the Correction Mode Settings dialog box, you can select an input color from another location in your Avid application, such as a custom color swatch in a bin, using the eyedropper. You can also double-click the output color swatch and select a color from the Windows Color dialog box or the Macintosh Color Picker. These alternatives are useful for selecting a saved "ideal" replacement color such as a completely neutral gray or an optimal skin tone. For more information on using the Windows Color dialog box or the Macintosh Color Picker, see Using the Windows Color Dialog Box or Using the Macintosh Color Picker.
5.  Click the Match Type button, and select a Match Type to determine the exact nature of the match the system makes.
The options available in the Match Type pop-up menu depend on the group in which you are working. For more information on Match Type options, see Selecting Match Type Options.
6.  Click the Match Color button to make the correction.
The system adjusts the current segment and resets the group controls to reflect the adjustment. The corrected image displays in the monitor that contains the current segment.
