The King of Photoshopping...

Erik Johansson is a photographer and retouch artist working out of Berlin, Germany.  He's made a name for himself through his remarkable “photoshops”, like the one at right (click to enlarge).

Here's a portfolio of his work, and here's a TED talk he gave last November in London.  He's got an amazing eye for what would make an interesting photoshop, and an equally amazing talent for actually executing the idea.  Great stuff!
