You can enter a value between 50 and 500 for the gamma.
Note:
See “Image Controls” on page 2-30 for further information on adjusting
the gamma level.
Applying a Preset Tone Curve
You can finely adjust the contrast within an image by applying
one of the preset tone curves. This allows more control over the
image when used in conjunction with the Auto Exposure function
or settings in the Preview Window. The Tone Curve Name list in
the Tone Correction dialog box provides the six most common
tone correction curves, described below.
Linear
A linear tone curve has no tone correction. Use this setting if you
are satisfied with the tone of the preview image.
