Customizing Brushes 229
When the slider is moved fully to the left, the brush will leave a faint stroke —
even if Opacity is set to 100%.
To set clumping of bristles
1 On the Stroke Designer page of the Brush Creator, click Bristle.
2 Move the Clumpiness slider to the left to reduce bristle clumping. Move it to the
right to increase bristle clumping.
To set bristle density
1 On the Stroke Designer page of the Brush Creator, click Bristle.
2 Move the Hair Scale slider to the left to reduce the amount of bristle density and
create a fine-hair brush. Move it to the right to increase density.
To scale bristles according to brush size
1 On the Stroke Designer page of the Brush Creator, click Bristle.
2 Move the Scale/Size slider to the left to reduce the degree of size variation. Move it
to the right to increase size variation.
Well Controls
The Well controls determine how a brush conveys its medium (color) to the paper. The
Resaturation, Bleed, and Dryout controls work together to determine how much color
a brush has at the start and finish of a stroke. Some Well controls work in conjunction
with Expression settings. For more information about Expression settings, see
“Expression Settings” on page 262.
Brush Loading affects how dab-based brushes interact with underlying pixels. When
Brush Loading is active, brushes can literally “pick up” existing colors, hair by hair.
This capability offers truer color interaction, astounding color-variations smearing, and
better cloning results. For more information about dab-based brushes, see “Dab Types”
on page 205.
When Brush Loading is not active, brushes interact with previously applied colors by
sampling underlying pixels and then loading the brush with one new color — the
average of those colors that were sampled. When you use Brush Loading, it’s best to
use a very low setting for spacing. For more information about spacing controls, see
“Spacing Controls” on page 221.
