What is triangular light?
Rembrandt is a Dutch painter. In his portraits, the light and shadow treatment of the characters' faces adopts a strong contrast effect. The light comes obliquely from the upper part of the figure, which makes the nose of the figure project and blend into the dark part, making one cheek of the figure form a triangular bright area. We usually see a projection under the nose in the sun, which will gradually lengthen with the position of the sun. This is a fact, but it is only required that no projection can be made. Because this kind of light effect can make people's faces have obvious three-dimensional sense, later photographers imitated the characteristics of Rembrandt's paintings and produced this method of using light, which can strengthen or weaken the contrast of light ratio according to the characteristics of different characters. For example, people with low noses or flat faces can take pictures with this lamp, which can make up for their defects visually.
There is another way to explain triangular light.
Triangular light is a light distribution method. Also known as three-point lighting method, it is the basic lighting level in figure photography lighting. That is to say, the light levels of main light, auxiliary light and profile light are connected together to form a triangle. It is the three basic lights in the lighting of objects and people. Side light, also known as backlight, is often used as decorative light and isolation light (even if the main body of the picture is separated from the northern background). Three-point lighting is the basic lighting method for shooting portraits, but it is not the only method. The main light forms a 45-degree angle with the camera (that is, the positive side light), which can be used on both sides. The auxiliary light is near the camera, and the side light basically faces the direction of the lens, slightly higher. Rembrandt light is sidelight, which is the light effect that Rembrandt's paintings often show, but Rembrandt's paintings rarely use strong backlight.
