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 panel. Select a second brush tip from the Dual Brush section of the Brushes
panel, and set any of the following options.

A. Primary brush tip stroke (hard round 55). B. Secondary brush tip stroke (grass). C. Dual brush stroke (using both).

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 351.)

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.
