Lytro is an exiting new camera with some amazing technology, shortly to be released. The Lytro lets you capture and share what you see in an entirely new way. Unlike ordinary cameras, the Lytro records the entire light field, cpaturing all rays of light travelling in every direction through a scene. This means that you can endlessly refocus your images, after they have been taken!
I recommend visiting their website where you can try out this technology in their sample gallery (Go on, it’s fun!).
