The constraints of photography have been lifted. Gone is the split second lost during autofocus. Gone is an ill chosen depth of field. Gone is the need to squint at a blurry scene in the background of a portrait.
The picture revolution is coming according to Lytro, a company using light field technology to capture all the light rays in a scene with sensors. This allows "both the picture taker and the viewer to focus pictures after they’re snapped, shift their perspective of the scene, and even switch seamlessly between 2D and 3D views."
