How many ways can photographers play with photo lighting?

The simple lighting method for portrait shooting adopts the standard lighting principle: ▲ The main light is Polaroid 250 lamp cap with ultra-white reflective umbrella, which is placed at a 45-degree angle with the subject and raised appropriately. ▲ The auxiliary lamp is Polaroid 125 lamp cap, which is placed on the right side of the camera. When shooting, scattered light is transmitted through a translucent umbrella. ▲ The auxiliary light shines on the subject through 1 filter layer, while the main light shines on the subject through two filter layers, and then the strong light reflected by the ultra-white reflective umbrella shines on the subject. The lighting ratio of main lamp and auxiliary lamp shall be 3: 1. ▲ Use the flash exposure meter to get the comprehensive exposure index, which makes the face moderately sensitive and does not cause too much contrast.
