Chroma curve: Maps chroma in the original image (input) to the chroma of the image after editing (output). Moving a point on the curve upward makes colors in the affected portion of the color range more vivid, while moving it downward makes the affected colors less vivid, or grayer.

Width slider: Adjust the width of the curve that passes through the selected point, increasing or decreasing the range of colors affected by the change.

Exclude Gray: Neutral colors (grays) may seem over saturated when chroma is raised. Check this option to increase chroma without affecting grays. This option has no effect when chroma is reduced below the value in the original image.

Output slider: Moving the slider affects the saturation of all colors in the image.

Intensity: The amount by which the saturation of the selected point will be increased or de- creased in the output image.
