What is time-lapse photography?

1, Time-lapse photography, also known as time-lapse photography (English: time-lapse

Photography is a way to compress time. It takes a group of photos or videos, and then through photo stitching or video frame extraction, it compresses the process of minutes, hours or even days and years into a short period of time and plays it out in the form of video. In time-lapse photography video, the slow change of an object or scene is compressed in a very short time, presenting a strange and wonderful scene that is usually imperceptible to the naked eye. Time-lapse photography can be regarded as the opposite of high-speed photography. Time-lapse photography is usually used to shoot urban scenery, natural scenery, astronomical phenomena, urban life, architectural manufacturing, biological evolution and other topics.

2. Long-time fixed-frame delayed shooting. Also known as low-speed photography or fixed-time photography, "time-shrinking" photography. A means to record and reproduce the slow changing process of the scene with obvious changing images at regular intervals. For example, it takes about 3 days and 3 nights for a bud to bloom, which is 72 hours. Shoot one frame of it every half hour, record the subtle changes of flowering action in turn, shoot 144 frame at * * *, then show it with a projector at normal frequency (24 frames per second), and reproduce the flowering process for 3 days and 3 nights within 6 seconds.
