Smoothing selection edges with anti-aliasing and<br />

feathering<br />

Smooth the edges of a selection by anti-aliasing<br />

You can smooth the hard edges of a selection by anti-aliasing or feathering. Anti-aliasing smoothes the jagged edges<br />

of a selection by softening the color transition between edge pixels and background pixels. Because only the edge pixels<br />

change, no detail is lost. Anti-aliasing is useful when cutting, copying, and pasting selections to create composite<br />

images.<br />

You can select anti-aliasing with the Lasso, Polygonal Lasso, Magnetic Lasso, Elliptical Marquee, and Magic Wand<br />

tools. To anti-alias, you must select the Anti-Alias option before making the selection; you cannot add anti-aliasing to<br />

an existing selection.<br />

1 In the Edit workspace, select the Lasso, Polygonal Lasso, Magnetic Lasso, Elliptical Marquee, or Magic Wand tool.<br />

2 Select Anti-aliased in the options bar.<br />

3 Make a selection in the image window.<br />

Blur the edges of a selection by feathering<br />

❖ You can smooth the hard edges of a selection by feathering. Feathering blurs edges by building a transition between<br />

the selection and surrounding pixels. This blurring can cause some loss of detail at the edge of the selection.<br />

You can create a feathered selection with the Elliptical Marquee, Rectangular Marquee, Lasso, Polygonal Lasso, or<br />

Magnetic Lasso tool. You can also add feathering to an existing selection by using the Select menu. Feathering effects<br />

are apparent when you move, cut, copy, or fill the selection.<br />

1 In the Edit workspace, do one of the following:<br />

• Select any of the lasso or marquee tools from the toolbox, and enter a Feather value in the options bar to define the<br />

width of the feathering. The feathering begins at the selection border.<br />

• Select the Selection Brush tool, and select a soft-edged brush from the brushes pop-up panel in the options bar.<br />
