Control
| Description
|
|---|---|
Hue | Shifts the hues in the image around the color wheel. Values range from –180 to 180, where 0 is the default and causes no change in the image. A value of 120 shifts red to blue, and a value of –120 shifts red to green. |
Saturation | Specifies the amount or intensity of color. Values range from 0 to 200, where 100 represents no change to the image, 0 represents complete desaturation (monochrome image), and 200 represents maximum saturation. |
Brightness | Adjusts the luminance of the image by shifting the luminance value of every pixel by the value set in the control. Values range from –100 to 100, where –100 subtracts 100 from the 8-bit luminance value of every pixel, and 100 adds 100 to the 8-bit luminance value of every pixel. The effect of the Brightness control is very similar to that of the Setup control (on the Hue Offsets tab). One important difference, however, is that the Brightness control interacts with the Contrast control, while the Setup control interacts with the Gain and Gamma controls. If you have made a Contrast adjustment, it is better to adjust luminance further using the Brightness slider. If you have made an adjustment using the Gain or Gamma controls, it is better to adjust luminance further using the Setup control. |
Contrast | Increases or decreases the amount of contrast in the image. Values range from –100 to 100, where –100 represents no contrast (all pixels mapped to neutral gray) and 100 represents maximum contrast. |
Clip Low Clip High | Sets the Low clip and the High clip for the image. All pixels with the Low clip value or less are clipped to black; all pixels with the High clip value or more are clipped to white. The default settings for these controls are 16 and 235 on an 8-bit scale, representing the normal broadcast values for black and white. |
Invert Chroma | Replaces the color value of every pixel in the image with the opposite color value on the color wheel. This is the equivalent of setting the Hue control to 180 or –180. |
Invert Luma | Reverses the brightness level of every pixel in the image. Dark areas become light, and light areas become dark. |
