Color Correction

As used in this web site, color correction is the removal of unwanted color casts by neutralizing blacks, grays and/or whites.  Color balance is an image's overall color bias toward a primary or secondary color.  Color replacement is the changing of an object's hue without changing the object's underlining tone and texture.  The Color Balance page explains how to adjust an image's color balance.  Color replacement is discussed on the Spot Color Replacement page.

The two color correction controls discussed on this web site are Levels and Curves.  For each control, both the eyedropper technique and color channels technique are explained.  Click in the sidebar to go to the topic of your choice.
