Erasing
Sometimes the rubber end of the pencil can be just as important to an artist as the
pointed one. The Eraser Tools flyout on the Tools toolbar provides three ways of
enhancing an image by "painting" with transparency rather than with colour:
The Standard Eraser Tool for replacing
colours in an image either with the background
colour or with transparency (on Background or
other standard layers, respectively).
The Background Eraser Tool for erasing
pixels similar to a sampled reference colour
underlying the cursor crosshair—great for
painting out unwanted background colours, e.g.
when isolating objects or people photographed
against a studio backdrop.
The Flood Eraser Tool for filling a region
with transparency, erasing pixels similar to the
colour under the cursor when you first click.
In general, you can set tool properties including brush characteristics, opacity,
tolerance, flow, and choose a brush tip. The Eraser tools work on Background and
standard layers, but not on text layers or shape layers. Erasing on a depth map (see
Using depth maps on p. 145) adds variations that result in a 3D appearance.
