This whole “computational photography” thing always felt a little bit weird. But it also intrigued me. The idea that a computer can realistically create things that weren’t actually shown in the original shot is pretty amazing. Maybe it was seeing this scene in Blade Runner as a kid that did it for me. It was pure fantasy back then, but we’re getting there.
A new “computational zoom” technology developed by researchers at Nvidia and UCSB brings us a step closer to Deckard’s reality. Essentially it allows the photographer to change the focal length and perspective of an image in post, but this description barely does it justice. It actually allows you to simulate multiple focal lengths simultaneously. Here, watch this video, and it’ll all make sense.
