Lytro allows post-shot refocusing by taking advantage of something that conventional cameras cannot: the light field. The light field consists of all of the light rays in a scene, meaning every single light ray traveling in every direction through every point in space.
Scientists have fantasized about light-field cameras for a century, but previous experiments in creating one required the equivalent of 100 digital cameras connected to a supercomputer.
The Lytro takes that 100-digital-cameras-plus-supercomputer capability and stuffs it into a regular-sized point-and-shoot.
The company does this with an innovative sensor called a light field sensor. The light field sensor takes in three pieces of data about each ray of light: its color, intensity and direction. Conventional camera sensors just add up all the light rays and record them as one amount of light instead of recording information about each ray.
