The role of side light

Side light plays a role in outlining the main body. When the tones of the subject and the background overlap (for example, the subject is dark and the background is dark), the side light plays a role in separating the subject and the background. In artificial lighting, contour light is often used in combination with main light and auxiliary light, which makes the tone level of the picture varied and increases the aesthetic feeling of the picture form.
