ADOBE PHOTOSHOP CS2 

The Auto Color command adjusts the contrast and color of an image by searching the image to identify shadows, 
midtones, and highlights. By default, Auto Color neutralizes the midtones using a target color of RGB 128 gray and 
clips the shadows and highlight pixels by 0.5%. You can change these defaults in the Auto Color Correction Options 
dialog box. 

Do one of the following: 

Choose Image > Adjustments > Auto Color. The application of Auto Color is automatic with this option. You 
cannot adjust any of the options in the following steps. 

Choose Layer > New Adjustment Layer and choose either Levels or Curves. Click OK in the New Layer dialog box.

In the Levels or Curves dialog box, click the Option button.

Select the Find Dark & Light option under Algorithms in the Auto Color Correction Options dialog box.

Select the Snap Neutral Midtones option.

Adjust the amount of shadows and highlights that are clipped, and adjust the target color for the midtones.

Click OK in open dialog boxes to apply Auto Color.

The Auto Color Correction options control tonal and color corrections applied by Auto Color, Auto Levels, Auto 
Contrast, and the Auto option in both Levels and Curves. 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 dialog box or Curves dialog box, or you can save the 
settings as default values when applying Auto Levels, Auto Contrast, Auto Color, and the Auto option in Levels and 
Curves.
