• Picture — controls how much color appears in the image. At its lowest value, all color is washed out,
leaving only the highlights.
• Shine — controls how much highlight appears on the surface of brushstrokes. Higher Shine values
make the brushstroke look metallic.
• Reflection — maps a clone source image or pattern onto the texture at a variable percentage. For
more information, see “Creating reflection maps” on page 655.

Blending impasto with other layers
You can control how Impasto brushstrokes blend with images on other layers by selecting a Composite
Depth method in the Layers panel.
The Composite Depth menu provides the following methods for combining Impasto brushstrokes:
• The Add method, which is the default Composite Depth method, combines depth information
between layers. Brushstrokes on different layers build up where they overlap. If the composite depth
method is set to Add and you paint with an Impasto brush variant on a layer, the composite depth
setting does not change.
An example of the Add composite depth method.
• The Subtract method removes depth information between layers. Impasto brushstrokes on top layers
create grooves in the image data beneath them. If the composite depth method is set to Subtract and
you paint with an Impasto brush variant on a layer, the composite depth method does not change.
