When Photoshop can get you in trouble

The touched-up film poster
Keira Knightley is famously proud of her elfin figure. But it seems she was simply not up to scratch when it came to the poster for the movie King Arthur, and it was up to a Photoshop artist to invent what nature had only suggested, as these before and after shots demonstrate

Time's dark secret
It was unfortunate that Time and Newsweek both featured the police mug shot of OJ Simpson in the same week of publication. All the more unfortunate for Time, whose artists had darkened Simpson's skin, allegedly to make him look more threatening: or had Newsweek simply enhanced the shot? Either way, it proved we couldn't always trust the images we saw

The president's reading problem
George Bush is so dumb he can't even hold a child's book the right way up! Tee hee! Except, of course, the image is a fake. Look a the spine: the publisher's logo is at the top of the copy the girl is holding, and also at the top of his copy - it should be at the bottom

The anti-war rally that never was
This photo of John Kerry addressing a 1970s anti-Vietnam rally with Jane Fonda contributed to him losing the 2004 presidential election. The photo was a fake: the original images are still available. But by the time the deceit was made public, the damage had already been done

Shark attack
A composite of two photographs that gives the impression that a great white shark is leaping out of the water attacking a military helicopter next to San Francisco's Golden Gate Bridge was widely circulated via email in 2001, along with a claim that it had been chosen as "National Geographic Photo of the Year". The Photoshopped image was created by combining a picture of a HH-60G Pave Hawk helicopter, and a photo taken by South African photographer Charles Maxwell in False Bay, South Africa.
