Adjusting the Gamma Setting
Gamma is the difference in contrast between the light tones and
dark tones of an image. Any change you make in the gamma level
only affects the mid-tones of the image.
To change the gamma level of the image, move the
Gamma
slider left or right, or enter a value in the text box.
You can enter a value between 50 and 500 for the gamma.
Note:
See “Image Controls” on page 3-20 for further information on adjusting
the gamma level.
