Blend Modes

Blend modes let you mix the color and brightness of image layers. Below is an example of what can be achieved when combining two layers:

The program has 27 blend modes. Each layer is set to Normal by default.

A blend mode can be chosen for a set (group) of layers. If Pass Through is chosen from the blend mode drop-down list, then layers in a group will interact with each other and layers below in the usual way, as if they are not grouped. If another blending mode is chosen the set behaves as if the layers have been merged into one layer, which interacts with layers outside of the group based on the chosen blend mode. In this case the blend modes applied to individual layers within a set are only valid within the group and do not affect layers outside of the group.
