A plenoptic digital camera developed by Ren Ng, the founder of Lytro. The Lytro plenoptic camera allows the photographer to snap a picture from several different focal lengths at the same time by using a unique sensor resembling an insect's multi-faceted eye. The Lytro software that comes with the camera allows the photographer to alter the focus of the picture after the picture has already been taken. The camera is considered revolutionary and will forever change digital photography.
