Using Image Effects288
To create a color overlay:
1 Show the Colors and Papers
palettes.
2 Select a layer or area of the canvas.
If you want to apply the effect to
the entire image, make sure there
are no selections.
3 Choose a color from the Colors
palette.
If you want to base the color on a
paper grain, choose a paper texture
on the Papers palette.
4 Choose Effects menu > Surface
Control > Color Overlay.
5 In the Color Overlay dialog box,
choose a method from the Using
pop-up menu.
6 Move the Opacity slider until the
preview reflects the desired opacity.
7 Enable any of the following
options:
• Dye Concentration allows the
paper to absorb the color.
• Hiding Power allows the color
to cover what’s beneath it.
8 When you’re satisfied with the
settings, click OK to apply the
effect.
Dye Concentration
The Dye Concentration effect adjusts
color intensity and adds surface
texture by adjusting pigments. You can
use this effect to lighten an
underexposed photo or to darken an
overexposed one.
To adjust the dye concentration:
1 Select a layer or area of the canvas.
If you want to apply the effect to
the entire image, make sure there
are no selections.
2 Choose Effects menu > Surface
Control > Dye Concentration.
The Adjust Dye Concentration
dialog box is displayed. While the
dialog box is open, the controls on
the Papers palette can be adjusted.
3 Choose a method from the Using
pop-up menu:
• Uniform Color adjusts color
based solely on Maximum
slider values. The Minimum
slider has no effect. Setting the
Maximum slider above 100%
increases color density. A value
below 100% decreases it.
• Paper adjusts color using the
paper texture as a mapping
model.
• Image Luminance uses the
image’s brightness as the model
for the color adjustment.
• Original Luminance uses the
luminance of the clone source
as the model for the adjust-
ment.
• [Alpha channel] or [Layer
mask] uses the values in the
alpha channel or layer mask as
the model for the dye concen-
tration adjustment. You can use
this method only if you have a
saved channel or a layer mask
in your image.
4 Adjust the Minimum and
Maximum sliders as needed.
If you think of texture as peaks and
valleys, the Maximum slider
controls the amount of dye on the
peaks and the Minimum slider
controls the amount of dye in the
valleys. You can set Maximum as
high as 800%.
The lower you set Minimum,
which can be as low as 0%, the
higher the contrast between peaks
