Via /. We present a novel photographic technique called dual photography, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene. With a video projector providing structured illumination, reciprocity permits us to generate pictures from the viewpoint of the projector, even though no camera was present at that location. The technique is completely image-based, requiring no knowledge of scene geometry or surface properties, and by its nature automatically includes all transport paths, including shadows, interreflections and caustics. I need to really read this again and watch the video. Link.

The link doesn't work anymore /.-ed. I went through some of the mirrors linked from the slashdot page, but none worked. Anybody have a link to the video and paper that works?
