The Tone Curve tool is used to adjust the tonal distribution of each channel of
an image. It functions very much like the Gradation tool, except that it provides
additional functions to allow separate adjustments of the tones in each RGB or
CMYK channel, depending on the image type. This tool is especially useful for
correcting the “ink percentage” distribution (i.e., dot gain correction) in CMYK
images.

In the example here, the original image looks cold, with a decidedly blue-green
cast to it. The solution: Increase the “ink percentage” of the yellow and magenta
channels to bring out the warmer tones.

For details on how to read the tone curve, see the section on how to use the
Gradation tool.

Load a previously saved
tone curve for use with
another image. Photoshop-
saved curves can also be
loaded.

Save a tone curve together
with its settings so that the
curve can be used in the
future if necessary.

Choose the kind of curve
you wish to have. Select
from Curve, Line, or Gamma.
