Brush shape dynamics

Shape dynamics determine the variance of brush marks in a stroke.
Brush stokes without shape dynamics and with shape dynamics
Specifies how the size of brush marks vary in a stroke. For more information, see "Adding

brush dynamics" on page 336.
To specify the maximum percentage of jittering, type a number or use the slider to enter a value. To specify how you
want to control the size variance of brush marks, choose an option from the Control pop-up menu:
• Specifies no control over the size variance of brush marks.
Off
• Fades the size of brush marks between the initial diameter and the minimum diameter in the specified

number of steps. Each step is equal to one mark of the brush tip. The value can range from 1 to 9999. For example,
entering 10 steps produces a fade in 10 increments.
