Hardness Controls the transition of a brush stroke from 100% opaque at the center to 100% transparent at the edges. Even with high Hardness
settings, only the center is fully opaque.
Hardness settings at 100% (left) and 0% hardness (right)
Spacing The distance between the brush marks in a stroke, measured as a percentage of the brush diameter. When this option is deselected, the
speed at which you drag to create the stroke determines the spacing.
Decrease spacing for continuous strokes (left); increase spacing for dashed strokes (right).
Brush Dynamics These settings determine how the features of a pressure-sensitive digitizing tablet—such as a Wacom pen tablet—control and
affect brush marks. For each brush, you can choose Pen Pressure, Pen Tilt, or Stylus Wheel for Size, Angle, Roundness, Opacity, and Flow to
indicate what features of the pen tablet you would like to use to control brush marks. For example, you can vary the thickness of brush marks by
setting Size to Pen Pressure and pressing more firmly when drawing some portions of the stroke. If Size is not set to Off, Minimum Size specifies
the size of the thinnest brush mark.
Paint with the Brush tool
Use the Brush tool to paint on a layer in the Layer panel with the current foreground color.
Important: To specify settings for a paint stroke before you apply it, use the Paint and Brushes panels. To change and animate properties for a
paint stroke after you’ve applied it, work with the properties of the stroke in the Timeline panel.

To select a foreground color with the Color Picker, click the Set Foreground Color button in the Paint panel.
To select a foreground color from anywhere on the screen with the eyedropper, select the eyedropper in the Paint panel and then click to
sample the color under the pointer. Ctrl-click (Windows) or Command-click (Mac OS) to sample the average color of a 3-pixel by 3-pixel
square.
You can quickly activate the eyedropper for use within the Layer panel by pressing Alt (Windows) or Option (Mac OS) when the pointer is
in the Layer panel.
To switch the foreground color with the background color, press X or click the Switch Foreground And Background Colors button .
