Specifying paint dynamics (Photoshop)

Paint dynamics determine how paint changes over the course of a stroke.

To edit paint dynamics for a brush:

1. In the Brushes palette, select Other Dynamics on the left side of the palette. Be sure to click the name, rather than the check box, to select the item.
2. Set one or more of the following options:

Opacity Jitter and Control

Specifies how the opacity of paint varies in a brush stroke, up to (but not exceeding) the opacity value specified in the options bar. For more information, see About brush dynamics (Photoshop).

To specify a percentage by which the opacity of the paint can vary, type a number or use the slider to enter a value. To specify how you want to control the opacity variance of brush marks, choose an option from the Control pop-up menu:

• Off to not control the opacity variance of brush marks.
• Fade to fade the opacity of paint from the opacity value in the options bar to 0 in the specified number of steps.
• Pen Pressure, Pen Tilt, or Stylus Wheel to vary the opacity of paint based on the pen pressure, pen tilt, or the position of the pen thumbwheel.

Flow Jitter and Control

Specifies how the flow of paint varies in a brush stroke, up to (but not exceeding) the flow value specified in the options bar. For more information, see About brush dynamics (Photoshop).

To specify a percentage by which the flow of the paint can vary, type a number or use the slider to enter a value. To specify how you want to control the flow variance of brush marks, choose an option from the Control pop-up menu:

• Off to not control the flow variance of brush marks.
• Fade to fade the flow of paint from the flow value in the options bar to 0 in the specified number of steps.
• Pen Pressure, Pen Tilt, or Stylus Wheel to vary the flow of paint based on the pen pressure, pen tilt, or the position of the pen thumbwheel.
