With all methods other than Uniform
Color, pixels assigned higher luminance
receive a greater color adjustment.
Adjust Selected Colors
Adjust Selected Colors is similar to the
Adjust Colors effect, but it works only
on a specified range of colors within
an image. You choose a color in an
image and adjust colors within a range
of that color. You could, for example,
turn yellow peppers to red peppers.
You can adjust colors that are exactly
the same as the color you select, or you
can choose colors within a range,
based on proximity (on the color
wheel or color space) to the selected
color.
Selective color adjustments change only certain
colors in the image.
The Extents sliders determine the
extent of the HSV color space around
the selected center color:
• H Extents controls the number of
hues adjusted. Only hues within
the specified percentage of hues on
the color wheel are adjusted.
• S Extents controls the range of
saturation adjusted. Only
saturations within this range are
adjusted.
• V Extents controls the range of
values adjusted.
By combining these three settings, you
can set up a very specific range of
colors to adjust. For example, you can
limit changes to a very specific shade
of red.
Feather affects the softness at the edge
of the selected colors. These sliders
can help you create smoother
transitions between the replaced color
and the original.
A replaced color with and without feathering.
The choice of methods is the same as
for Adjust Colors. For more
information, refer to “To adjust
colors:” on page 269.
