Enhancing Images

The Color Lightness Channel

The Color Lightness channel controls the brightness of colors without affecting chroma or

hue. It can be used, for example, to brighten the blue of a dark sky.

Color lightness curve: Maps the brightness of colors in the original image (input) to the

brightness of colors after editing (output). Moving a point on the curve upward makes colors

in the affected portion of the color range more brighter, while moving it downward makes

the affected colors darker.

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.

Intensity: The amount by which the brightness of colors under the selected point will be

increased or decreased in the output image.
