Missing Blend Modes

A number of Photoshop layer blend modes are unavailable in PhotoImpact. I have not found an equivalent for Color Dodge, Color Burn, etc.

The PS blend mode called Screen appears as Reverse of Multiply in PI.

The PS blend mode called Linear Dodge appears as Addition in PI.

The PS blend mode called Linear Burn can be created by inverting the background layer and then using the Subtraction blending mode in PI.

For a mathematical explanation of the various blending modes, see this detailed page.
