My Apple 5 upgraded the ios8 system and added time-lapse photography. Is this time-lapse photography just to make the picture faster, or what?

Time-lapse photography can be regarded as the opposite of high-speed photography. 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.

To put it bluntly, it is to sample the images at some time points with a camera for a period of time, and then play these images frame by frame at a certain frame rate. For example, the camera freezes a picture, takes 1440 photos at the same time interval within 24 hours, and then plays them at the speed of 24 frames per second. It only takes 60 seconds to play all the pictures taken in 24 hours, so naturally it seems that the picture becomes faster.

Slow motion shooting, this is the opposite process. Shooting a picture at a high frame rate, and then playing it at a frame rate of 24 frames or slower, looks slow. You should be able to understand if you have done free fall in the physics experiment of Louzhu High School.
