Dual brushes

A dual brush combines two tips to create brush marks. The second brush texture is applied within the brush stroke

of the primary brush; only the areas where both brushstrokes intersect are painted. Set options for the primary tip

in the Brush Tip Shape section of the Brushes palette. Select a second brush tip from the Dual Brush section of the

Brushes palette, and set any of the following options.

Brush strokes created with a single tip (left) and with dual tips (right)

Mode Sets a blending mode to use when combining brush marks from the primary tip and the dual tip. (See “List

of blending modes” on page 344.)

Diameter Controls the size of the dual tip. Enter a value in pixels, drag the slider, or click Use Sample Size to use the

original diameter of the brush tip. (The Use Sample Size option is available only if the brush tip shape was created by

sampling pixels in an image.)

Spacing Controls the distance between the dual tip brush marks in a stroke. To change the spacing, type a number,

or use the slider to enter a percentage of the tip diameter.

Scatter Specifies how dual tip brush marks are distributed in a stroke. When Both Axes is selected, dual tip brush

marks are distributed in a radial direction. When Both Axes is deselected, dual tip brush marks are distributed

perpendicular to the stroke path. To specify the maximum percentage of scattering, type a number or use the slider

to enter a value.

Count Specifies the number of dual tip brush marks applied at each spacing interval. Type a number, or use the slider

to enter a value.

Color dynamics Brush options

Color dynamics determine how the color of paint changes over the course of a stroke.
