Ren Ng Regular Quotations

Basically, with a regular camera, you have to take time or allow the camera to focus before you take the shot.

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.

When a regular camera focuses physically, what the regular camera is doing is adjusting the lens relative to the sensor to bring different parts of the scene into focus.

If you think about all the light that enters - that enters the lens of a camera, that's much more than a photo. The light field is all the higher-dimensional information that's lost in a regular photo. When we record all this information, that provides us the opportunity in software after the fact.
