I may have already posted this, and if I did you’ll have to excuse me BUT, this is great enough to post twice. From what I gather it’s a new kind of camera tech. According to their marketing mumbo-jumbo, the Lytro Light Field Camera captures “light rays from the light field” (a normal camera “cannot record the light field”) so “the picture taker and the viewer [can] focus pictures after they’re snapped, shift their perspective of the scene, and even switch seamlessly between 2D and 3D views.” Blah blah blah the point is, you can shoot first and then focus (and ask questions) later. So basically between RAW and Lytro, basically you just have to point the camera in the general direction of the thing you want to photograph and then later when you get home and you’re sitting on your couch you can fudge around with the important stuff like focus and exposure.
