layer below the Woman Standing layer.

2. Press D to set the default colors and then press Alt+Backspace to fill the current layer (Backdrop)
with the foreground color. You now have a black backdrop behind the figure. Figure 4.8 shows
artifacts that are only visible on screen when viewing the figure against a black backdrop.

Figure 4.8
Artifacts are visible along many of the edges.
Artifacts are easier to
spot against black.

Color bleeding from the background is visible along these edges.

Saturated color from the background that bled onto the figure caused color halo artifacts to
appear on many edges. Let’s correct this with the Color Replacement tool.
3. Click the Woman Standing layer in the Layers palette. Select the Color Replacement tool in the
toolbox. (It may be hidden under the Healing Brush.) You can also access the Color Replace-
ment tool by pressing Shift+J multiple times to cycle through the Healing Brush, Patch, and
Color Replacement tools. On the Options bar, set Mode to Color, Sampling to Continuous,
Limits to Contiguous, and Tolerance to 15%, and check Anti-aliased.
