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 Image Controls dialog box. The tone correction 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.

Lighten

Adjusts darker images (like underexposed film) to make them slightly brighter.

Darken

Adjusts brighter images (like overexposed film) to make them slightly darker.

Flat Contrast

Flattens high contrast images to make them look more natural.

High Contrast

Increases the contrast of dull images.

Open Shadow

Improves details in the dark areas of images.

Note:

See Using the Tone Curve and Tone Correction for more information on tone correction.
