Recently the public has become aware of the potential of light field photography through the introduction of the Lytro camera
. Light field recording allows an enormous degree of post-processing, letting you create just the image you want to print and display. A print, however, expresses only one aspect, no matter how carefully chosen, of the recorded light field. Can light field information be somehow encoded into a print, so an object can be examined from this side and that, or with different lighting conditions? A team of researchers at the University of California at Santa Cruz, Hewlett-Packard Laboratories, and 3M have made the first steps toward a positive answer by developing reflectance paper.
