Using the Auto Contrast and Color Commands

The Auto Contrast command adjusts the tonality of the image without impacting color. The Auto Color command adjusts the tonality and color of the image by ignoring channels and looking directly at the image. The automatic color commands receive their adjustment queues from information within the active image, including any erroneous color information. For example, if the image contains a large border (typically white), the auto commands will factor that information into the correction of the image. It's best to correct any dust, and scratch problems, and crop out any borders before applying the auto contrast and color commands.
