Set brush pressure sensitivity for digitizing tablet

Set brush sensitivity if you are using a pressure-sensitive digitizing tablet, such as the Wacom® tablet.

Select the Brush tool , the Pencil tool , or other painting tool in the toolbox.

Click the Brushes tab to bring the Brushes palette to the front or, if the palette isn't open, choose Window > Brushes.

To make the tool tip size change with pressure, select Shape Dynamics (be sure to click the word, not just the check box) in the Brushes palette. Then choose Pen Pressure from the Controls pop-up menu under the Size Jitter slider control.

To make the opacity change with pressure, select Other Dynamics. Then choose Pen Pressure from the Controls pop-up menu under the Opacity Jitter slider control.

Note: You can set Pen Pressure for other brush characteristics as well. The Brush palette contains controls that vary the angle, flow, scatter, texture depth, and roundness of the stroke depending upon the pen pressure.
