Adobe Photoshop CS5 One-on-One

Choose Edit→Undo or press Ctrl-Z (�-Z on the Mac) to go one

step back. Lo and behold, Photoshop reveals what the image

looked like before the clean-up cropping. As you can see in

Figure 2-9, before the crop there were wedges filled with the

background color (which is white by default). Photoshop au-

tomatically cropped the wedges, leaving as much of the image

as possible intact but necessarily trimming some of the photo

as well.
