Ren Ng Rays Quotations

Unlike regular digital or film cameras, which can only record a scene in two dimensions, light field cameras capture all of the light rays traveling in every direction through a scene. This means that some aspects of a picture can be manipulated after the fact.

For low light, all the light rays participate. We're using all the light coming through a large aperture to make a picture with a large depth of field - totally impossible with a conventional camera.
