"With Hurricane Sandy approaching the New York metro area, the nation's eyes are turning to its largest city. Photos of storms and flooding are popping up all over Twitter, and while many are real, some of them -- especially the really eye-popping ones -- are fake.
This post, which will be updated over the next couple of days, is an effort to sort the real from the unreal. It's a photograph verification service, you might say, or a pictorial investigation bureau. If you see a picture that looks fishy, send it to me at alexis.madrigal[at]gmail.com. If you like this sort of thing, you should also visit istwitterwrong.tumblr.com, which is just cataloging the fakes.
The fakes come in three varieties: 1) Real photos that were taken long ago, but that pranksters reintroduce as images of Sandy, 2) Photoshopped images that are straight up fake, and 3) The combination of the first two: old, Photoshopped pictures being trotted out again."
