Brush strokes with different hardness values
Spacing Controls the distance between the brush marks in a stroke. To change the spacing, type a number, or use
the slider to enter a value that is a percentage of the brush diameter. When this option is deselected, the speed of the
cursor determines the spacing.
Increasing the spacing makes the brush skip
While using a preset brush, press the [ key to decrease the brush width; press the ] key to increase the width. For hard
round, soft round, and calligraphic brushes, press Shift+[ to decrease the brush hardness; press Shift+] to increase
the brush hardness.

Adding brush dynamics
The Brushes palette 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). A warning icon appears if you select a pen control but have not installed a
tablet.
