It turns out that the 2013 World Press Photo of the Year -- the largest and most prestigious press photography award -- was, in actual fact, a fake. The World Press Photo association hasn't yet stripped the photographer, Paul Hansen, of the title, but presumably it's just a matter of time. Rather than discussing the politics of photo manipulation, though -- is it faked, or is it merely enhanced? -- we're going to look at how Hansen managed to trick a panel of experienced judges with his shooping skillz, and how a seasoned computer scientist spotted the fraudulent forgery from a mile off.
