SHOOT TIME-LAPSE MOVIES IN-CAMERA
Time-lapse involves taking a large number of images at regular intervals, then stitching them together into a video, giving the impression of time being sped up. Until recently, time-lapse was an involved process, as you needed an interval timer to take your images, then specialist software to create the movie. Now though, many cameras have time-lapse functionality, where they take your shots at timed intervals (you choose the interval and the total number), then automatically stitch them. To calculate the length of your video (in seconds), divide the total number of shots by 25.
