Curve Editor

The curve editor is where the majority of enhancements are made within the Levels & Curves tool. Within
the curve editor, you are presented with a histogram that presents the total luminosity values within your
image. Superimposed above this histogram, a curve is displayed that enables you to control the relationship
of input luminosity values to output luminosity values.
