The Gradation dialog box
Check to enable the Saturation Range option.
Then drag the sliders or enter the values in
the edit boxes to define the saturation
(chroma) range. The colors outside the
chroma range will not be affected by the
Gradation curve.
In this example, the lower chroma section (0
to 50) will be affected by the Gradation
adjustment. The higher chroma section (51 to
100) outside the chroma range will not be
affected.
Defining a chroma range is helpful if you wish
to prevent images from losing saturation or
color intensity.
Click to create handles from
which to drag and manipulate
a segment of the curve.
The more handles are created,
the easier and smoother it is to
manipulate the curve.
To remove a handle, drag it
off the graph or the grid.
