24 CHAPTER 1 THE BASICS

Figure 1.23
The shape has a black
stroke across it.

Figure 1.24
Drawing in black on a
mask hides part of your
layer.

This time, the black brush stroke was painted on the mask. Black pixels on the mask hide the
gradient layer.
7. Press X to exchange the foreground and background colors. Paint yet another brush stroke
across the mask (see Figure 1.25).
This time you were painting with white on the layer mask. This exposes the Gradient layer.
Most important, notice that by painting with a soft brush, you can get partial exposure through
the mask, leaving a soft edge. This occurs because there are some gray pixels on the mask at the
edges of the brush stroke, partially revealing the Gradient layer.
