The Chroma Editor enables you to
edit the Chroma, or saturation, of the
entire image or of specific colors within
the active image without affecting
Luminosity or Hue.
Within the Chroma Editor, you are
provided with a Hue Map, represent-
ing the full spectrum of colors on the
horizontal axis, with the Chroma of the
colors of the vertical axis. Superimposed
above this Hue Map, you are provided
with a Chroma Curve that can be used
to isolate and adjust the Chroma of
individual colors.
Clicking on the curve will create an
anchor point. Moving that anchor point
upward makes colors in the affected
portion of the color range more
saturated. Taking that same anchor
point and moving it downward makes
the affected colors less saturated.
Anchor points can be removed by
simply clicking and dragging the anchor
point off the Hue Map.
Use the Width slider to increase or
decrease the range of similar colors
affected by the color identified with the
anchor point.
The Output slider affects the satura-
tion of all of the colors throughout the
image evenly. Moving this slider up will
increase the saturation of all colors,
while moving this slider down will
decrease the saturation of all colors.
The Chroma Editor contains a number
of additional controls:
Exclude Gray
Check this box to prevent any satura-
tion increases from affecting neutral
colors (grays) in the image. This is
helpful as neutral colors (grays) may
seem oversaturated when chroma is
raised.
Please note : The Exclude Gray
option has no effect when chroma is
lowered below the value in the original
image.
Set Anchor Point
Click on this button and then click on
the active image to select a color to
place an anchor point on the Chroma
Curve.

Chroma Editor to the default values.
