What kind of lighting does photography have? What is this?

Parallel light is light from the back of the camera. Because the light shines evenly on the surface of the subject from the front direction, the light receiving area is large and there are few shadows. It is relatively easy to measure light and control exposure when shooting. Even if the automatic exposure mode is used, exposure errors generally do not occur. However, its shortcomings are obvious-even if the surface of the subject is uneven, it is not easy to appear shadows because of the same light intensity, which will cause the subject to lack texture and three-dimensional sense, and the whole photo looks flat. Frontal light is especially unsuitable for big scenes, such as landscapes or portraits (usually you will find that in big photos taken along the light, there are only two black holes left in everyone's nose.

Side light refers to the light coming from the side of the photographed object, which can make the surface of the photographed object show some shadows due to unevenness, so that the light receiving surface and the light and dark surface of the object have obvious performance, which can not only outline the outline of the photographed object, but also reflect the three-dimensional sense. This kind of light is the most expressive, so side light is the most commonly used light when taking pictures. However, when using it, we should pay attention to the proportion of light-receiving surface and dark surface in the picture modeling. Usually, the angle of oblique light is the best. When the direction of light forms an angle of about 45 degrees with the plane of the scene, the light of this angle makes the ratio of the light-receiving surface to the dark surface of the object roughly equal, which is more in line with people's visual habits in daily life.

Backlight refers to the light that shines from the back of the subject. Backlight photography is easy to make the subject become a silhouette, so it is relatively difficult to grasp the exposure. Backlight photography is often not recommended for beginners. But the artistic effect of backlight is also unique-backlight can set a moving silhouette light edge on the outer edge of the subject (if it is sunlight, it is Phnom Penh). If handled properly, it can create a unique aesthetic feeling and shoot a sense of light and shadow full of artistic breath.

It should be noted that when taking photos with backlight, the light ratio between foreground and background is too large, which often leads to overexposure or underexposure of background. In order to reduce the light ratio, you must pay attention to fill the foreground with light, you can use a reflector or a flash-if you see someone using a flash when shooting against the light, you should pay full respect to him, because he is an expert and he is narrowing the light ratio between the foreground and the background.
