How to Apply One-Step Auto Fixes in Photoshop Elements 11
Auto Color Correction
The Auto Color Correction command adjusts both the color and contrast of an image, based on the shadows, midtones, and highlights it finds in the image and a default set of values. These values adjust the number of black and white pixels that Elements removes from the darkest and lightest areas of the image.
You usually use this command to remove a colorcast or to balance the color in your image. Sometimes this command can be useful in correcting over- or undersaturated colors.
