It’s easy to forget when watching a movie that we’re actually viewing a series of still images. Because these images whiz by at a rate of 25 images (or frames) per
second, the footage appears to run in ‘real time’.
However, if you capture just one image every second (instead of the usual 25) then play the shots back at the usual rate, you’ll see a dramatic increase in the speed at which time passes. This technique is called time lapse photography, and you can produce it using an iPhone and iMovie. You need to capture a series of shots at regular intervals so they flow smoothly. Here’s how to capture and edit your time lapse sequence.
