Tone Curve tool
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.
For details on how to read the tone curve, see the section on Gradation tool.
Load a previously saved
tone curve setting to apply to
current image. Photoshop-
saved curves can also be
loaded.
