How many images should be in a light field? The largest known light field (of Michelangelo's statue of Night) contains 24,000 1.3-megapixel images. At a deeper level, the answer depends on the application. For light field rendering (see the Application section below), if you want to walk completely around an opaque object, then of course you need to photograph its back side. Less obviously, if you want to walk close to the object, and the object lies astride the "st" plane, then you need images taken at finely spaced positions on the "uv" plane (in the two-plane parameterization shown above), which is now behind you, and these images need to have high spatial resolution.
