Applying AutoExposure Without Removing an
Image’s Color Cast
Sometimes an image has a distinctive overall color, or
color cast
. AutoExposure automatically looks for and
balances any color cast in the image.
Although you will usually want to remove a color cast
from your scanned images, 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.
To activate AutoExposure
without
correcting an
image’s color cast, hold down the Shift key and click
the AutoExposure button
.
The AutoExposure
adjustments are only made
to the part of an image
inside the crop frame. Try
adjusting the frame size
before applying the
AutoExposure feature to
create various effects.
