The Auto Color Correction options control the automatic tone and color corrections available in both Levels and Curves. It also controls the
settings for the Auto Tone, Auto Contrast, and Auto Color commands. The Auto Color Correction options let you specify shadow and highlight
clipping percentages, and assign color values to shadows, midtones, and highlights.
You can apply the settings during a single use of the Levels or Curves adjustment, or you can save the settings as default values when applying
Auto Tone, Auto Contrast, Auto Color, and the Auto option for Levels and Curves.

1. Click the Levels or Curves icon in the Adjustments panel.
2. Alt-click (Windows) or Option-click (Mac OS) the Auto button in the Properties panel (CC, CS6) or Adjustments panel (CS5).
3. Specify the algorithm you want Photoshop to use to adjust the overall tonal range of an image:
Clips all channels identically. This preserves the overall color relationship while making highlights
appear lighter and shadows appear darker. The Auto Contrast command uses this algorithm.
Maximizes the tonal range in each channel to produce a more dramatic
correction. Because each channel is adjusted individually, Enhance Per Channel Contrast may remove or introduce color casts. The Auto
Tone command uses this algorithm.
Finds the average lightest and darkest pixels in an image and uses them to
maximize contrast while minimizing clipping. The Auto Color command uses this algorithm.
