How to set Nikon's time-lapse shooting?

First of all, the definition of "delayed shooting" should be made clear here.

1. In the mobile phone photo APP software, there is a software called "time delay photography", which takes multiple photos at regular intervals and finally synthesizes a gif animation file. It is suitable for photographing the flow of clouds in the sky, the busy scene of urban road traffic, or the image of flowers in full bloom. In Nikon's high-end SLR cameras, there is an "interval shooting" function, which is equivalent to the "time-lapse shooting" function of mobile phones. You can refer to the "interval shooting" item in the manual. Generally speaking, the interval time is determined according to the moving speed of the subject, and the shooting times are calculated according to the required length of the short film.

2. shoot regularly. It is also a way to take photos at certain intervals, but in the end, instead of synthesizing a gif animation, multiple photos of a scene at different times are formed. It is necessary to photograph the orbits of stars. Finally, these (usually dozens of photos) are combined into a star orbit map by using the superposition function of PS. Timing shooting function is not available in all SLR cameras, and it is usually completed by means of electronic wire release (camera uses B door). In the era when there is no release of electronic wires, it is really hard work to control shooting manually by photographers.
