User Guide
Roundness Specifies the ratio between the brush’s
short and long axes. Enter a percentage value, or
drag the points in the left preview box. A value of
100% indicates a circular brush, a value of 0%
indicates a linear brush, and intermediate values
indicate elliptical brushes.
Adjusting roundness affects shape of brush tip.
Saving, loading, and replacing brushes
The Brushes palette can hold as many brushes as
you want. Creating sets of brushes can help you
group related or special brushes and manage
palette size. The Adobe Photoshop program folder
includes files containing various brush sets.
To save and use custom brush sets:
Choose one of the following commands from the
Brushes palette menu:
•
Reset Brushes to return to the default brushes.
You can either replace the current brush set or
append the default brushes to the current set.
•
Load Brushes to add brushes stored in a file to
the current palette.
•
Replace Brushes to replace the current brush set
with brushes stored in a file.
•
Save Brushes to save a brush set in a file (and in
Windows, append an .abr extension to the
filename).
Exiting Photoshop saves the current Brushes
palette in the Preferences file.
