1. Apparatus comprising, in combination: (a) a screen for displaying images at some times, which images are perceptible to a human viewer, and for displaying a dynamically adjustable spatial light modulator pattern at other times; (b) one or more light-sensing devices for taking measurements of light from a scene, which light falls upon, or passes through, the screen; and (c) one or more processors for using the measurements to calculate a light field that describes direction and intensity of light rays that comprise the light; wherein the apparatus is configured such that when the light from the scene intersects a plane in the apparatus, a plurality of regions exist in at least part of the plane, such that each respective region out of the plurality of regions is illuminated by light from a particular direction, which particular direction applies to only one region out of the plurality of regions.
