I really like this next feature. You can preview the selection on the actual image by selecting a Selection Preview Method. "White Matte" generally shows up the most obvious. When you select a method, your image will show a preview of the resulting selection, or mask. You can see here how easy it is to determine how well the selection process worked, since the white mannequin is very nicely covered in white, while just a couple specks remain outside. Good enough for me! At this point, it is time to press "OK" to create a selection from which the rest of the process stems.
