Researchers have unveiled a new photography technique called computational zoom that allows photographers to manipulate the composition of their images after they’ve been taken, and to create what are described as “physically unattainable” photos. The researchers from the University of California, Santa Barbara and tech company Nvidia have detailed the findings in a paper, as spotted by DPReview.

In order to achieve computational zoom, photographers have to take a stack of photos that retain the same focal length, but with the camera edging slightly closer and closer to the subject. An algorithm and the computational zoom system then spit out a 3D rendering of the scene with multiple views based on the photo stack. All of that…
