Color Overlay controls

• Use Color — lets you choose the overlay color

• Opacity — controls how transparent the effect is

• Dye Concentration— allows the paper to absorb the color

• Hiding Power — allows the color to cover what lies beneath it

Applying the Dye Concentration effect

You can adjust the dye concentration in an image to control color intensity and play with surface texture.

For example, use this effect to lighten an underexposed photo or to darken an overexposed one. You need

to choose a method for applying the effect. Some methods, such as Paper, generate more texture than

other methods, such as Uniform Color. There are five different methods for applying dye concentration:

• Uniform Color — allows you to adjust only color density

• Paper — adjusts color by using the paper texture as a mapping model. If you want open to experiment

with the effect, keep the Papers panel open while you apply the effect. This way you can switch to

different papers and modify the paper controls.

• Image Luminance — uses the image’s brightness as the model for the color adjustment

• Original Luminance — uses the luminance of the selected pattern or clone source as the model for the

adjustment

• Alpha Channel or Layer Mask — sets the values in the alpha channel or layer mask as the model for

the dye concentration adjustment. You can use this method only if you have a saved channel or a layer

mask in your image.
