Motion Parallax This photograph of waiters in India passing a tray from one train car to the next captures the visual flavor of motion parallax. Objects that whiz by faster are perceptually judged as being closer, as in the case here of the blurred ground and bushes. Objects that pass by more slowly are judged as being farther away, as conveyed by the clearer details of buildings and more distant objects.
