Why does the side light look ugly?

Side lighting will look ugly because it can't illuminate the whole face. For people with non-stereoscopic facial features, the defects will be magnified, and the five senses will be uncoordinated because of the shadow of side light.

The shape of the face seen by human eyes depends on the way light shines on the feature surface and plane. By setting the position of the light, you can emphasize or weaken some functions. The traditional textbook-style main light position is 45 on the actor's side, and then 45 upward.

Side light is light from the side. In actual shooting, the main light rarely hits like this because it can't beautify the characters. The effect of hitting the face is called yin and yang teacher. Of course, some portraits of stars are also taken on purpose.

Photographic polishing technology

Under the same conditions, it is better to shoot with far main light than with near main light. This is an important concept to choose the position of the main light. In typical multi-scene and multi-camera coverage shooting, when the camera faces an actor, the actor is either on the left side of the camera or on the right side of the camera, so his face is not facing the camera directly, but slightly to one side.

If an actress faces the camera from the left, the right side of her face is more likely to appear in front of the camera than the left side. So, the left is far and the right is near. The far main light shines on the far side of the face and leaves some shadows on the near side of the actor's face. This illumination shapes facial features (formed by the shadow lines of nose, lips, eyes, mouth and chin) by presenting contrast to the camera.
