Correct Quickly with Auto Color
posted by photoboy27
The Auto Color command in Photoshop can be a quick and convenient way to correct images that should have a fairly typical color balanceparticularly if you quickly become lost when making manual Levels and Curves adjustments. But avoid choosing the Auto Color command from the Image menu’s Adjustments sub-menu. Instead, you can control this feature more precisely through the Levels dialog box.
1. Create a new Levels adjustment layer.
2. Click the Options button in the Levels dialog box.
3. In the Auto Color Correction Options dialog box, select the Find Dark & Light Colors and Snap Neutral Midtones options. If the image doesn’t look right, try other Algorithm options. Turning off Snap Neutral Midtones may improve the image if there aren’t any neutral gray tones in the image.
4. Fine-tune the Clipping values. Default clipping values should be set to between 0 and 0.5% as a starting point. Then you can move up from there in small increments by pressing the up arrow and down arrow keys on the keyboard. Back off when the image starts to lose highlight or shadow detail. As an alternative, you can click the Shadow and Highlight boxes to set their target values with eyedroppers. If the adjustments you’ve made so far have not corrected the color balance, click the Midtones swatch and adjust the values; equal values in all three RGB channels neutralize a typical image.
5. Click OK. Photoshop might ask you if you want to save the current settings as the defaults. You can do so if you’re going to work on more images that will need similar corrections. It’s a good idea to save defaults that have Find Dark & Light colors selected and Snap Neutral Midtones turned on, because you’re going to want those options to be on for most images.
