A time-lapse is a video animation made by taking a series of photographs at different times in order to show in a short time how the photographed object has evolved over a long period of time. It can for example be used to show the opening of a flower, the movement of the Sun or stars in the sky, or even the building of a house. The final file is in the form of a video or in animated Gif format.
Time-lapse in cinematography
In cinematography, the process consists in filming at a lower speed, i.e. with a smaller number of images per second than will be used in projection. To the viewer the film appears to be accelerated.
