Clicking the Remove Background button in the Picture Tools Format tab’s Adjust group
displays the Background Removal tab, shown in Figure 10-31, which normally remains hidden.
Figure 10-31 The Remove Background button works well on some images.
When you first click the Remove Background button, the image appears with selection
handles inside its frame and, as Figure 10-31 shows, shaded areas that represent areas
specified for removal. The selection handles indicate where the image will be cropped. The
shaded areas are selected around the periphery of the image and are based on
predominant, common, adjacent colors and—to some extent—lines and textures. You can drag the
selection handles to include more or less of the image in the result, and the shaded areas
might change when you do this. If the automatic selection doesn’t quite get it right, you
can use the Mark Areas To Keep and Mark Areas To Remove buttons, which do pretty much
what they indicate. When you mark an area, you might find that an area has a lot more
colors than it appeared to at first, so trial and error is helpful here. The Undo and Redo
buttons work beautifully. In Figure 10-31, we simply dragged the bottom of the selection
rectangle a bit, to include the entire finial, and the automatic background selection algorithms
worked pretty well for this image.
The remaining menu in the Picture Tools Format tab’s Adjust group is Artistic Effects, which
includes a number of textures, screens, and various other types of distortions and
manipulations. The very nice Pencil Grayscale effect is shown in Figure 10-32.
