Selection Brush Tool

Settings

The following settings can be adjusted from the context toolbar:

• Mode—sets the way in which your selection develops as you paint:
  • Add—the brush stroke adds areas to the current selection. If there is no selection in place, you will create a new selection by painting.
  • Subtract—the brush stroke removes areas from the current selection.
• Width—the brush (stroke) size in pixels. Type directly in the text box or drag the pop-up slider to set the value.
• Snap to edges—selection is expanded to the edges of content underneath the brush stroke.
• All layers—if this option is off (default), the selection is only applied to the current layer. When selected, the selection applies to all layers in your image.
• Soft edges—if this option is off (default), edge pixels are fully opaque, which may result in a ragged appearance. When selected, edge pixels are anti-aliased for a softer appearance better suited to compositing against a new background.
• Refine—click to display the Refine Selection dialog to access advanced selection settings.
