Got a spare six minutes? Here’s photographer Erik Johansson presenting a TED talk about his ‘Impossible Photography.’ It’s really pretty cool. He creates very realistic looking images—meaning they’re very well done, not that they look real. But they’re actually surrealistic because of the content; many images display an M.C. Escher-like optical illusion quality. This photographer’s work is as much about retouching and digital manipulation, but it’s really unique and well worth a look—even if you’re not interested in creating your own out-of-this-world fantasy images. After the TED talk, check out Johansson’s web site to see even more images and order your own prints.
