How to use hot shoes to trigger the flash to shoot portraits in the micro-single-shot shed? What is the effect of micro-single snapshot?

Nice theme! Your question and answer actually contains two questions, which are described as follows.

1, there are two main themes in studio shooting: portraits and products (including macro and still life shooting). However, what you want to know in your question should be mainly literal portraits. A formal photo studio usually has many professional photographic lights. Coincidentally, I also set up my own personal studio in my early years, so I have a general understanding of the basic elements of photography in the studio. Generally speaking, professional photographic lights, such as the U2 series I used at that time, have three synchronization modes. One is directly connected to the camera, the other is wireless flash, and the flasher is inserted in the hot shoe. The third type is to install camera hot boots with a flash lamp, with a flash lamp. In practice, most of them still use the methods of 1 and 2. In order to create the light of the eyes, many times lights will be placed around the plane, and the lights will dim. The flash mentioned in your question can also be used directly on the plane. However, this kind of lamp is mainly used for flashing and making eye light, and is rarely used as a main and auxiliary lamp.

Shooting in the shed is really professional. Location shooting (including scenery) mostly uses natural light passively, and the studio actively creates light. The difference lies in passivity and initiative. Photography is the painting of light. Always remember this sentence. Therefore, lighting is the key to shooting in the studio. As for shooting, just ask your assistant to press the cable and release it as instructed.

2. About snapshots. In terms of equipment, SLR or paraxial is still recommended. The real snapshot has no time for you to focus on the scene calmly, and the shutter has no time lag. At present, micro-orders are still lacking. The most reliable way to shoot an ideal lens is to focus on 35mm, with small wide-angle depth of field and confident shooting range, and generally focus on hyperfocal distance. Finally, the most important thing is to practice blind shot well, where to play without taking pictures!
