• Subtract — When this method is
active, depth information between
layers is removed. Impasto brush
strokes on top layers create grooves
in the image data beneath them.
Painting with an Impasto variant
on a layer with Subtract set does
not change the composite depth
setting.
An example of the Subtract Composite
Method.
• Replace — When this method is
active, layer masks replace the
depth information from lower
layers with information from top
layers. Wherever strokes overlap,
only the top stokes are visible; the
lower strokes are completely
covered.
Painting with an Impasto variant
on a layer with Replace set does
not change the composite depth
setting.
An example of the Replace Composite Method.
• Ignore — When this method is
active, Impasto brush strokes do
not interact with image data on
different layers.
With Ignore active, the display of
depth for the layer is turned off,
even when the View Depth icon
on the document window is active.
This makes it possible to disable
display of depth for individual
layers.
Painting with an Impasto variant
on a layer with Ignore set changes
the method to Add.
This is the default composite
method.
You can set a different composite
method for every layer in a document.
Refer to “Blending Layers Using
Composite Methods” on page 248 for
more information.
