Creating dual brushes (Photoshop)

A dual brush uses two tips to create brush marks. You set options for the primary tip in the Brush Tip Shape section of the Brushes palette. You set options for the secondary tip in the Dual Brush section of the Brushes palette.


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

To edit dual tip options for a brush:

1. In the Brushes palette, select Dual Brush on the left side of the palette. Be sure to click the name, rather than the check box, to select the item.
2. Select a blending mode to use when combining brush marks from the primary tip and the dual tip. (See Selecting a blending mode.)
3. Select a tip for the dual brush from the list below the Mode pop-up menu.
4. Set one or more of the following options:

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.
