Photographic lighting bitmap, high-key, medium-key, low-key. How to fight separately? Please tell me the light map.

High-profile: brighten the white background, make one or two side backlights as the main light, fill the front light, and expose according to the front.

Intermediate tone: the front side light is the main light, the background is properly treated, and the exposure is carried out according to the main light.

Low-key: black background, the main body with strong light modeling, high-light exposure, appropriate to add half a step.

High-profile and low-key have little to do with equal potential. High-profile usually uses a white background, and then the background is very bright, which is equivalent to a pure white background to highlight the main body. Low profile is the antonym of high profile. The key to high-profile and low-key is exposure. Taking a high profile can appropriately increase the exposure, and taking a low profile can appropriately reduce the exposure. I hope you can understand and wish you success!
