10.21.  Stretch Contrast

This command is somewhat similar to Normalize plug-in in its effects, except that it works on each color channel of the layer individually, rather than just the brightness values. This usually leads to color shifts within the image, so it may not produce the result you are looking for. Stretch Contrast operates on layers from RGB, Grayscale, and Indexed images.
