How is the instantaneous growth of plants filmed in the documentary?

The delay of time-lapse photography can be longer or shorter. For example, the video of flowers is actually not too long. Many flowers bloom for tens of minutes, not as long as you think. Here is a little knowledge. Many flowers bloom for a long time, but they don't bloom only once. For example, the lotus blooms at midnight in the early days of opening, closes in the afternoon and blooms again at midnight the next day.

Only in the second half of the flowering period, it will not be closed again in the afternoon, which is basically a state of residual load. Most flowers will not experience any day and night changes in the process of opening, and the time is very short.

Others, such as the process of plant growth, take many days, and most of them can see the day and night changes in the video, but in the editing selection screen, the night part will be slightly less.

Longer time-lapse photography, if a great god once took a delay calculated in months, it is basically a photo every day, not to mention worrying about the alternation of day and night.

Besides, there is nothing mysterious about time-lapse photography. Video movies are essentially photos that are played continuously. Previous movies were all 24 frames, that is, 24 photos were played every second. The same is true when shooting, playing 24 photos per second. Because of the visual residue of glasses, the picture you see is dynamic.

If the shooting time and playing time are not synchronized, it is slow or fast. Take one picture every second, but play 30 pictures every second during playback, so that the picture you see is 30 times faster than the actual picture. This is also time-lapse photography. If we shoot one every minute, shoot 1440 every 24 hours, and play 30 pictures every second, then you can see the 24-hour continuous motion for 48 seconds.
