The difference between slow photography, time-lapse photography and fast playback

Slow photography is called time-lapse photography in English. We know that the standard shooting speed of movies is 24 frames per second. Therefore, the so-called micro-speed photography simply means that the camera takes many photos at a time interval much slower than the standard speed, and then uses these photos to make a movie, in order to show the changing process of the subject in a short time.

Time-lapse photography is a photography technique that takes an image or video at a low frame rate and then plays the image at a normal or faster rate. In time-lapse photography video, the slow change process of an object or scene is compressed into a very short time, showing 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, biological evolution and so on.

The process of shooting time-lapse photography with a camera is similar to making a freeze frame, which connects single still pictures in series to get a dynamic video.

Long-time freeze time delay 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.
