Digital Watercolor Controls
Digital Watercolor controls let you create effects similar to those of Watercolor brushes
without requiring a separate layer.
The Diffusion slider is used to create soft, feathery edges on the brush strokes. For
more information about diffusion, see “Digital Watercolor Diffusion” on page 172.
The Wet Fringe slider controls the amount of pooling of water and paint at the edges
of Digital Watercolor brush strokes. For more information about wet fringe, see “Wet
Fringe” on page 173.
Artists’ Oil Controls
The Artists’ Oil controls are divided into three critical components: Paint, Brush, and
Canvas. You can control Artists’ Oil brushes’ size and opacity with a tablet expression.
For more information about setting brush size, grain and opacity, see “General
Controls” on page 204. For more information about Expression settings, see
“Expression Settings” on page 262.
The Grain slider on the property bar affects the look of Artists’ Oils by controlling the
level at which paper absorbs paint. When the Grain slider is set to 0%, the paper
absorbs a very limited amount of paint; no paper grain is visible in the stroke and the
paint color appears lighter. When the Grain slider is set to 100%, the paper
completely absorbs the paint; no paper grain is visible, and the paint color appears
darker. Grain is visible with Artists’ Oils when the Grain slider is set between 1% and
99%. As an Artists’ Oils brush runs out of paint, paper grain becomes more visible, so
the the Amount slider also affects how much grain appears.
