Brightness level of photographic light

Light level refers to the irradiation direction of the light source and the position of the light source relative to the subject. In photography, the intensity of light determines the bright and dark position of the subject, and also affects the texture and shape of the subject. The light level can be varied, but when the position of the subject and the camera is relatively fixed, the light level can be divided into six types: front light, side light, back light, top light, foot light and scattered light.
