Do the following in the options bar:
•
Choose a Limits mode for erasing: Discontiguous to erase the sampled color wherever it
occurs under the brush; Contiguous to erase areas that contain the sampled color and
are connected to one another; Find Edges to erase connected areas containing the
sampled color while better preserving the sharpness of shape edges.
•
For Tolerance, enter a value or drag the slider. A low tolerance limits erasure to areas
that are very similar to the sampled color. A high tolerance erases a broader range of
colors.
•
Select Protect Foreground Color to prevent the erasure of areas that match the
foreground color in the toolbox.
•
Choose a Sampling option: Continuous to sample colors continuously as you drag;
Once to erase only areas containing the color that you first click; Background Swatch to
erase only areas containing the current background color.

Drag through the area you want to erase. The background eraser tool pointer appears
as a brush shape with a cross hair indicating the tool’s hot spot
.
Using the Auto Erase option
The Auto Erase option for the pencil tool lets you paint the background color over areas
containing the foreground color.
To use the Auto Erase option:
1
Specify foreground and background colors. (See
“Choosing foreground and
background colors” on page 257
.)
2
Select the pencil tool
.
3
Select Auto Erase in the options bar.
4
Drag over the image.
If the center of the cursor is over the foreground color when you begin dragging, the area
is erased to the background color. If the center of the cursor is over an area that doesn’t
contain the foreground color when you begin dragging, the area is painted with the
foreground color.
Using the art history brush tool (Photoshop)
The art history brush tool lets you paint with stylized strokes, using the source data from a
specified history state or snapshot. By experimenting with different paint style, size, and
tolerance options, you can simulate the texture of painting with different colors and
artistic styles.
