Slit-Scan Photographs Make For Psychedelic Photo Finishes

Slit-Scan Photographs Make For Psychedelic Photo Finishes

Slit-scan photography works much like a rolling shutter does — the sensor continually collects image data but the shutter never actually closes, hence its use in determining a “photo finish” — whatever crosses the camera’s view first, appears first in the photo set. Or at least that’s how its supposed to work.

Slit-scan photography is also really useful for creating psychedelic art where colours flow from a point. You can see examples of it in 2001 during the “stargate” sequence or just about every single time the USS Enterprise stretched as it entered Warp Drive in The Next Generation. But what happens when the latter effect happens during the former event? Our friends at Oobject have assembled 12 examples of these far out photo finishes.

If those photos havent got you questioning physics, check out these images of atoms, universes, and everything between; some movies about moving picture machines, and these camera cars.
