What can be the intermediate dimming effect?

Side light. In photography, intermediate dimming refers to the light between light and dark, whose light and dark changes gently and the color is realistically restored. Smooth lighting produces an intermediate tone effect, because it can evenly illuminate the object, reduce the contrast, the color of the object will be fully displayed, and the details will be clearly visible; The side light will produce strong contrast and obvious shadows, form a sharp outline, and make the audience's attention focus on specific parts. When the two kinds of light are added and balanced, the light effect of the middle tone will reach the best state.
