What's the difference between Rembrandt light and triangle light?

Rembrandt light and triangular light are no different, they are all the same light, but they are called differently. Triangular light is a kind of light distribution method, also called three-point light distribution method, which is the basic light distribution level in figure photography lighting, that is, the main light, auxiliary light and contour light are connected into a triangle, which is the three basic lights in figure lighting. Contour lights, also known as backlighting, are often used for decorative lights and isolation lights. Three-point light distribution is the basic way to use light in portrait shooting, but it is not the only way. The main light forms a 45-degree angle with the camera, and the auxiliary light is near the camera.

Rembrandt ran out:

Rembrandt is a world-famous Dutch painter. Rembrandt lighting is a special lighting technology specially used to shoot portraits. When shooting, the shadow face of the subject's face faces the lens, and the light illuminates three quarters of the face. The portrait shot by this light method resembles Rembrandt's portrait, hence the name. Rembrandt's lighting technology highlights the subtlety of each face, that is, the two sides of the face are different. The lighting effect can also be adjusted arbitrarily with auxiliary light according to the photographer's wishes. Although Rembrandt-style Gao Fancha lighting is very interesting, proper use of reflector and auxiliary light to minimize the contrast can achieve the effect of strengthening the whole portrait, thus making extraordinary works. Generally speaking, Rembrandt needs two lamps for lighting, and the former Three Lamps District area is used to adjust the improved contrast. It can reflect some light to the dull side of the face. Lighting can shine light on the face of the subject through the reflector, which weakens the obvious Rembrandt triangle and brightens the overall tone of the portrait. Background light plays a role in brightening the background.
