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.
Use the Auto Contrast Command
Open an image.
Click the Image menu, point to Adjustments , and then click Auto Contrast .IMPORTANT
Use the Auto buttons (Levels, Contrast, Color) buttons only if you do not understand how to manually control the image using powerful adjustments, such as Levels and Curves.
Use the Auto Color Command
- Open an image.
- Click the Image menu, point to Adjustments , and then click Auto Color .
Did You Know?You can use a selection to define how the Auto Contrast and Auto Color commands work. If the image contains a border, and you don't want the Auto command using the border to influence the correction, simply select the Rectangular marquee and draw a border around the image. When the Auto command is applied, only the selected areas will be adjusted. |
