How to measure the light of a flash portrait by a five-level photographer? Which is the main light or the auxiliary light? How to measure the comprehensive photometry?

What the hell is a five-level photographer? I've never heard of it. . .

Portrait photometry method:

For example, if you have a Three Lamps District now, you can decide the main light and the auxiliary light according to the position of the lights.

Now there are lights 1, lights 2 and 3. Then how do you put this 123 light?

If the lamp 1 is placed at the front or side of the model, and the lamps 2 and 3 are placed at the back of the model for ambient light or other purposes, then we can think that the lamp 1 is the main lamp, and the lamps 2 and 3 are the auxiliary lamps.

A lamp that illuminates a subject or model can be called a main lamp. As a light for background or other purposes, we can call it an auxiliary light.

About how to measure light, it needs to be adjusted all the time. There is no standard measurement method. You need to determine the light source according to the number of shots or the subject.

The above is just a summary of personal experience, not others. . I hope I can help you. . Come on!
