All
Selecting this from the Channels
pull-down Menu applies the current
enhancement to all of the channels of
the image.
When this option is selected in the
Channels pull-down Menu, you are
provided with an Opacity slider to alter
the effect of the enhancement.
Opacity
Use this slider to control the entire
opacity of the current effect. Move the
slider to the left to reduce the opacity
of the effect if the effect is too strong
for your taste.
Luminance and Chrominance
The Luminance and Chrominance option
enables you to control the amount
of the current effect on either the
Luminance (lightness) or Chrominance
(color) portions of your image.
When this option is set within the
Channels pull-down Menu, you are
provided with two sliders:
Opacity (Luminance Channel)
Use this slider to control the amount
of the current effect on the Luminance
portion of the image. Move this slider
to the left to reduce the amount of the
current effect on the luminance aspect
of the image. This can be done to
ensure that the current enhancement is
being applied only to the color aspects
of the image.
Opacity (Chrominance Channel)
Use this slider to control the amount of
the current effect on the Chrominance
portion of the image. Move this slider
to the left to reduce the amount of
the current effect on the chrominance
aspect of the image. Reduce this slider
to 0% to apply the current enhance-
ment to the Luminance portions of the
image so that no effect on the color is
being made.
RGB
Selecting this option from the Channels
pull-down Menu provides you with the
ability to control the current enhance-
ment's effect on the Red, Green, and
Blue channels separately using individ-
ual sliders:
Opacity (Red Channel)
This slider controls the amount of the
current effect on the Red channel of
the image. You can move this slider to
the left to prevent the current effect
from being applied to the Red channel,
or you can reduce the other two sliders
to ensure the current effect is being
applied to the Red channel only.
Opacity (Green Channel)
This slider controls the amount of the
current effect on the Green channel
of the image. You can move this slider
to the left to prevent the current
effect from being applied to the Green
channel, or you can reduce the other
two sliders to ensure the current effect is
being applied to the Green channel only.
