Excuse me, what is forward light and reverse light?

Front light, also known as front light, is lighting in which the light projection direction is always consistent with the camera shooting direction. Backlight: Also called background light, the light behind the subject is illuminated. Because it can only illuminate the outline of the subject from the back, it is also called sidelight.

Characteristics of daylight lighting: the light used is dull, not stereoscopic enough compared with other light used, and the texture is not very strong. The subject receives light evenly, the shadow of the scene is blocked by itself, and the tone is soft, which can hide the bumps and wrinkles on the surface of the subject, but it will be dull if it is not handled properly. The three-dimensional sense of the performance space is also very poor. On the other hand, due to the direction of light, the camera is not prone to glare and other problems. After the sunlight is refracted into an appropriate angle by the atmosphere, it can show the blue sky and make the picture transparent, so it is most popular with photographers who like location.

The characteristics of backlight: reflect the light of lines and highlight the outline. ? There are three forms of backlight: front backlight, side backlight and top backlight. In the case of backlight, most scenes are in the shadow, and only the outline of the photographed scene distinguishes this scene from another scene, so there are distinct layers. This kind of light is often used to shoot panoramas and distant views. Because it is necessary to control the light more carefully when using this lighting technology, it is usually considered as a more advanced lighting technology.

Backlight is a kind of lighting with artistic charm and strong expressive force, which can make the picture produce an artistic effect completely different from the actual light we see with the naked eye at the scene.

Backlight photography is a means of taking pictures by using light. Broad backlight should include full backlight and side backlight. Its basic characteristics are: from the light level, total backlight is the light emitted from the subject with his back to the camera, also called "backlight"; The side backlight is the light from the camera's left and right 135 back to the subject. The light receiving surface of the subject accounts for 1/3, and the backlight surface accounts for 2/3.
