Levels & Curves
The Levels & Curves feature combines
two of the most often used tonal
enhancing features into one easy-to-
use editor. The Levels & Curves feature
enables you to adjust contrast, tone
levels (brightness), and color balance to
make maximum use of the tone range
and color gamut offered by a particu-
lar output device, such as a printer or
monitor.
The Levels & Curves feature provides
you with controls to make tonal adjust-
ments to specific portions of the active
image's tone range for either the entire
image or to specific color channels,
making it possible to enhance the
image while preserving detail.
Within the Levels & Curves dialog, you
are provided with the option of first
selecting which channel, or portion of
colors, that you want to affect. The Levels
& Curves Editor begins by default editing
all of the channels (Red, Green, and Blue)
within the image simultaneously. If you
would like to change this, simply click on
the Channel pull-down Menu to select
one of individual channels, Red, Green,
or Blue.
Hint: You can access each of these
