Selecting parts of an image

You can smooth the hard edges of a selection by anti-aliasing or feathering. Anti-aliasing smooths the jagged edges of 
a selection by softening the color transition between edge pixels and background pixels. Because only the edge pixels 
change, no detail is lost. Anti-aliasing is useful when cutting, copying, and pasting selections to create composite 
images.

You can select anti-aliasing with the Lasso, Polygonal Lasso, Magnetic Lasso, Elliptical Marquee, and Magic Wand 
tools. To anti-alias, you must select the Anti-Alias option before making the selection; you cannot add anti-aliasing to 
an existing selection.

Select the Lasso, Polygonal Lasso, Magnetic Lasso, Elliptical Marquee, or Magic Wand tool.

Select Anti-aliased in the options bar.

Make a selection in the image window.

❖

You can smooth the hard edges of a selection by feathering. Feathering blurs edges by building a transition between 
the selection and surrounding pixels. This blurring can cause some loss of detail at the edge of the selection.

You can create a feathered selection with the Elliptical Marquee, Rectangular Marquee, Lasso, Polygonal Lasso, or 
Magnetic Lasso tool. You can also add feathering to an existing selection by using the Select menu. Feathering effects 
are apparent when you move, cut, copy, or fill the selection.

Do one of the following:

•

Select any of the lasso or marquee tools from the toolbox, and enter a Feather value in the options bar to define the 
width of the feathering. The feathering begins at the selection border.

•

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

Make a selection in the image window.

Use a selection tool from the toolbox to make a selection.
