Treehugger has a post that shows some PhotoShopped video game art, particularly those for covers that never quite made it print.
Nearly all of the photos you've seen in magazines have been airbrushed and Photoshopped to eliminate traces of imperfection.
That was just the craziest "underwear" (most of it had to be Photoshopped) I've seen.
They also Photoshopped away the dark circles that had been under her eyes since meeting Jonny in the hospital.
In some cases it's a cinch to see when an overzealous fan has Photoshopped the heck out of an image of a star.
