How to control the photographic light ratio

The control of light ratio can only wait for time or weather, and the light ratio can also be changed by adjusting the shooting angle. But in portrait photography, manual intervention is often used to control the light ratio. Outdoor portrait photography can reduce the light ratio by reflecting plate, or increase the light ratio by absorbing plate (black).

Light ratio is one of the important parameters in photography, which refers to the light reception ratio between the dark side and the bright side of the subject under the illumination environment. The light ratio is of great significance to the contrast control of photos. Photographers introduce the concept of light ratio in order to better control the contrast of the picture.
