Digital technology has advanced to the point where anyone can doctor a photograph. Sometimes it takes a technical expert to tell the difference between a real photo and a fake one. One such expert, Hany Farid writes for the Scientific American about some of the best examples of photo doctoring in the digital age. He also gives some telltale signs of fake photographs, suggesting that sleuths focus on the eyes, the light sources, and the pixels.
Some Photoshop doctoring jobs don’t need an expert to be exposed as a fake. The blog Photoshop Disasters has become a time-wasting favorite on the internet, chronicling some of the worst photo doctoring in the media, including errant limbs, one-legged models, and other human oddities. There are even a few egregious errors from fairly reputable sources. My favorite (seen left) is from Sports Illustrated, where someone seems to have cut off a man’s head. The question is: How did they miss that?
