I saw an iPhone ad recently that portrayed changing the focus on an image from a foreground object to background one, and back, and thought, hmm, I should try that. Turns out: 1) you have to do the changing on your phone and not on the image downloaded to a laptop (like this was, for posting); and, 2), the image has to be in focus to begin with. Still, I know more now!
