New Scientist - Card trick holds promise for movie effects

A bunch of people sent in links to the Dual Photography site, but it seemed a little too tech-y to post yet. Today NewScientist has a shorter summary of what it is and what it means for the effects industry. The basic idea is that they hit an object with light from a projector and take a digital photo from a different angle, and then are able to extrapolate an image of the view from the projector just from the reflected light. It's a neat trick, but the New Scientist article adds,

Eventually, dual photography could be used to alter lighting after a movie scene has been filmed or to add photorealistic virtual objects and characters that cast realistic shadows in post-production.
