How long does it take to take a 3-minute time-lapse photo?

Time lapse photography takes about 2 hours and 3 minutes.

First, determine the real time of shooting. For example, if you want to shoot a two-hour real-time process and make the video have five minutes, you should first know that the frame rate of a general video is 1.24 frames/sec, which is 24 frames/sec, so you can calculate as follows:

The first video was shot for 5 minutes, or 300 seconds.

300 seconds times 24=7200 frames, that is, 7200 photos, 2 hours of real time, that is, 2×60×60=7200 seconds.

7200 shots in 7200 seconds, that is, 7200 seconds ÷7200 shots = 1 second, with an interval of one second.

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.
