Image Gamma is used to adjust the colors in the
image that will be scanned into the computer. Gamma
values follow a smooth curve, as seen below in Figure
16. By adjusting the gamma, you can change the tonal
range of the selected color channel. Gamma values are
primarily a measure of the brightness of a color. The
larger the gamma value, the brighter the color
becomes. Adjusting the gamma on the Master channel
affects the tonal range for all colors equally. And
adjusting the gamma for the individual Red, Green or
Blue channels only affects pixels containing that color.
Click on a color channel and then drag the slider bar
near the bottom of the window to adjust the image
gamma.
