Using Auto Adjust
The Auto Adjust tool checks the image for the brightest and darkest
points and sets the highlight and shadow points according to a preset
formula. It also adjusts the midtones to align with the extreme points for
an overall brighter image. Use Auto Adjust for color or grayscale images;
it isn’t needed for line art (1-bit Line Art [OCR]).
You can also use Auto Adjust to mark particular color casts in the image
for removal or preservation from automatic adjustments. See Removing
or Preserving a Color Cast for details.

a Color Cast
Sometimes an image has a distinctive overall color, or color cast . Auto
Adjust looks for and balances the color by removing any dominating color
casts in the image. Usually you’ll want to remove dominating color casts
from your scanned images, but sometimes a color cast may be desirable.
For example, a photograph of a sunset might have red color cast. In this
case, you probably would not want to remove the color cast.
Auto Adjust affects only
the part of the image
inside the active frame.

adjustments to a larger

If you’re using one of
the Polaroid modes,

a custom Auto Adjust
mode for the Polaroid
