Spacing

Adding brush dynamics

The Brushes panel provides many options for adding dynamic (or changing) elements to preset brush tips. For
example, you can set options that vary the size, color, and opacity of brush marks over the course of a stroke.

You work with two components when adding dynamics elements to a brush:

Jitter percentages specify the randomness of dynamic elements. At 0%, an element does not change over the course
of a stroke; at 100%, an element has the maximum amount of randomness.

Options in the Control pop-up menus specify how you want to control the variance of dynamic elements. You can
choose not to control the variance of an element, to fade an element over the specified number of steps, or to vary
an element based on pen pressure, pen tilt, position of the pen thumbwheel, or pen rotation.

Note: Pen controls are available only when you’re using a pressure-sensitive digitizing tablet such as the Wacom
tablet, and supported pens (for rotation control and thumbwheel). A warning icon appears if you select a pen control
but have not installed a tablet or are using a pen that is missing the control feature.
