Why didn't you shoot in slow motion and time delay?

The main difference between slow photography and time-lapse photography lies in the different shooting methods.

The so-called slow photography means shooting at a slow shutter speed. It usually takes a few seconds or 30 seconds, so most of the photos taken are virtual, so a tripod is needed. For example, taking pictures in dim light is to slow down the shutter speed in order to ensure exposure because of insufficient light. If the photographer shakes his hand slowly, the photo will be burnt, so it is best to use a tripod for slow photography.

Time lapse photography is also called time lapse photography. It's a way to compress time. You took a group of photos, or, through the concatenation or frame extraction of later photos, the minutes, hours or even days, months and years were compressed in a short time and played in a new way.

For example, playing the process of flowers blooming and falling in one minute is actually compressing the process of slowly changing objects or scenery into a very short time in a time-lapse photography, showing a strange and wonderful scene that is usually imperceptible to the naked eye.

In addition, time-lapse photography is a kind of photography opposite to high-speed photography. High-speed photography is to shoot fast-moving objects with high-speed cameras, and then play them out in slow motion. For example, usually the bullet leaves the gun chamber.
