09 Time Lapse Photography

Edgerton took his strobes under water to record the leisurely life of the sea floor, using time-lapse photography.

This method combines a motion-picture camera with a strobe.  At regular intervals, the strobe flashes and a single frame of film is exposed and advanced.  When the movie is shown at normal speed, the action is speeded up greatly, turning barely-perceptible movement into rush hour.

Watch this video in which Doc Edgerton explains the benefits of “speeding up” and “slowing down” time!
