What do you mean, pinch the lamp?

Light clamping: divided into left and right light clamping and up and down light clamping. As the name implies, two lamps are mainly used to illuminate at a certain angle up and down or left and right respectively. You can shoot flat and beautiful light effects, and you can also shoot stereoscopic light with a certain brightness. The effect is the light on both sides of the object, which gradually changes from the edge to the center, showing a good three-dimensional effect, but there are also some problems of skin texture and color change. Light cutting in portrait photography is a widely used lighting method, which is convenient, fast, changeable and easy to control. There are many methods of light editing, but the basic changes are the same. Many lighting combinations have evolved on the basis of light clipping, such as butterfly lights.
