time lapse

Time lapse is a method of filming where frames are shot much slower than their normal rate, allowing action to take place between frames, and giving the appearance of the action taking place much faster in the finished product; often done for nature filming (the blooming of a flower, the movement of clouds, etc.), allowing the viewer to witness the event compressed from real-time (hours or days) into a few seconds. Time lapse is the opposite of "slow-motion."
