Ever heard of a light field camera? Neither had I. Imagine snapping an image without having to focus. Later, with software, you can play with exactly where in the frame you want the focus to be. The Lytro camera is the by-product of a Ph.D. dissertation by Ren Ng. It is due on the market late this year and is apparently to be a point-and-shoot camera, which means it might be afordable. The Lytro website has some images up that you can play with. Explore the focus on the test images. It is an unbelievable experience. Imagine having the freedom to concentrate only on the framing and moment of a picture. Focus can be determined later. Wow!
