Inverting masks

Ordinarily, a mask constrains its tool’s effect to be inside all of its regions. Occasionally, it’s useful to be able to use a mask to specify an area of your photo to exclude from a tool’s effect. You can invert a mask to do this.

To invert a mask for a tool:

  1. Select the tool whose mask you want to invert by clicking its title bar.
  2. Make sure the Tool Settings tab is selected.
  3. Click the tool’s invert-mask box.
