Absolute Beginner's Guide to Digital Photography

Selecting Anti-Aliased in the options bar smoothes the jagged edges of a selection

and is useful when cutting, copying, and pasting selections to create composites.

The Tolerance setting determines which pixels will be selected. A low Tolerance set-

ting (10, for example) will select only pixels that are almost exactly the same in

brightness and color to the pixel you click on; a high Tolerance setting (120) will

allow more pixels in the selection (see Figure 10.12).
