Specifying the paint fade-out rate
You can specify the rate at which the pencil, paint-
brush, airbrush, and eraser fade out from their
beginning strokes, simulating actual brush strokes.
To set a fade-out rate:
In the tool's Options palette, for Fade, enter a
1
value for the number of steps of the fade.
Each step is equal to one mark of the brush tip. The
value can range from 1 to 9999. For example,
entering 10 steps produces a fade in 10 increments.
For the pencil, paintbrush, or airbrush tool,

Transparent to fade the stroke from the
•
foreground color to transparency.
Background to fade the stroke from the
•
foreground color to the background color.

Adobe Photoshop is compatible with most
pressure-sensitive digitizing tablets such as the
Wacom tablets. With Control Panel software for
your tablet installed, you can specify the type of
effect that results when you vary stylus pressure.
These stylus pressure options affect the magnetic
lasso, magnetic pen, pencil, paintbrush, airbrush,
eraser, rubber stamp, pattern stamp, history
brush, smudge, blur, sharpen, dodge, burn, and
sponge tools.
To set the effect of different stylus pressures:
Double-click the desired tool to display its Options
palette, and select one of the following options:
Size to have increased pressure create a bigger
•
brush stroke.
Opacity/Pressure/Exposure to have increased
•
pressure make the paint more opaque or more
intense.
