Count Jitter and Control Specifies how the number of brush marks varies for each spacing interval. To specify the

maximum percentage of brush marks applied at each spacing interval, enter a value. To specify how you want to

control the count variance of brush marks, choose an option from the Control pop-up menu:

• Off Specifies no control over the count variance of brush marks.

• Fade Fades the number of brush marks from the Count value to 1 in the specified number of steps.

• Pen Pressure, Pen Tilt, Stylus Wheel, Rotation Varies the number of brush marks based on the pen pressure, pen

tilt, position of the pen thumbwheel, or rotation of the pen.

Textured brush options

A textured brush uses a pattern to make strokes look as if they are painted on textured canvas.

Brush strokes without texture (left) and with texture (right)

Click the pattern sample, and select a pattern from the pop-up palette. Set one or more of the following options:

Invert Inverts the high and low points in the texture based on the tones in the pattern. When Invert is selected, the

lightest areas in the pattern are the low points in the texture and therefore receive the least paint; the darkest areas in

the pattern are the high points in the texture and therefore receive the most paint. When Invert is deselected, the

lightest areas in the pattern receive the most paint; the darkest areas in the pattern receive the least paint.

Scale Specifies the scale of the pattern. Type a number, or use the slider to enter a value that is a percentage of the

pattern size.

Texture Each Tip Applies the selected texture individually to each brush mark in a brush stroke, rather than to the

brush stroke as a whole (a brush stroke is made up of many brush marks, applied continuously as you drag the

brush). You must select this option to make the Depth variance options available.

Mode Specifies the blending mode used to combine the brush and the pattern. (See “About blending modes” on

page 343.)

Depth Specifies how deeply the paint penetrates into the texture. Type a number, or use the slider to enter a value.

At 100%, the low points in the texture do not receive any paint. At 0%, all points in the texture receive the same

amount of paint, therefore hiding the pattern.

Minimum Depth Specifies the minimum depth to which paint can penetrate when Depth Control is set to Fade, Pen

Pressure, Pen Tilt, or Stylus Wheel, and Texture Each Tip is selected.
