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 settings
in the Manual mode 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.
