What's the name of the way to speed up the day and the hour?

Time lapse photography. The technique of shooting the sky for hours to speed up is called time-lapse photography. It is a shooting method that takes several minutes, ten minutes or even several hours. It compresses the material into several seconds and plays it out in ten seconds.
