Preserve Opacity is an easy way to selectively reveal part of an object. In this example,

by setting the blend mode of the top color wash layer to Exclusion, you get the

resulting image:

By turning on Preserve Opacity for the color wash layer on top, only the overlapping

parts are displayed, and the superimposed image only affects the Dolphin layer.

To turn on Preserve Opacity:

Turn on an object’s Preserve Opacity checkbox in the Properties tab.
