Why can you film the process of flower opening? How was it taken? It's amazing! !

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.
