Researchers with the University of California, Santa Barbara (UCSB) and NVIDIA have detailed a new type of technology called ‘computational zoom’ that can be used to adjust the focal length and perspective of an image after it has been taken. The technology was detailed in a recently published technical paper, as well as a video (above) that shows the tech in action. With it, photographers are able to tweak an image’s composition during post-processing.
According to UCSB, computational zoom technology can, at times, allow for the creation of ‘novel image compositions’ that can’t be captured using a physical camera. One example is the generation of multi-perspective images featuring elements from photos taken using a telephoto lens and a wide-angle lens.
