This lesson will tell you about the knowledge of photographic lighting, so that novices can better and faster understand these basics of photography.
1. What is the light ratio
The light ratio, popularly speaking, is the contrast of light, which can also be called light difference, which is determined by the proportion of light and shadow in the picture.
2. What is Shunguang
Shunguang is the most commonly used light in our photography, the so-called shunguang, that is, the light is directed to illuminate the subject, the direction of the light is consistent with the direction pointed by the lens, and the shunguang is the simplest and easiest to take the photo successfully (make the exposure accurate) a kind of light. The advantage of Shunguang is that the details of the picture taken can be fully displayed, the whole picture is clear and bright, the disadvantage is that the contrast is small, the picture is plain and ordinary, and the audience is not impressed.

3. What is the side light
Side light, that is, the light comes from 90 degrees in the shooting direction, that is, from the 90 degrees direction on the side of the lens, and shines on the subject. Side light can make the subject light and shade very obvious, very layered, and the audience's feeling is very good. Using side light shooting, there is a little difficulty relative to smooth light exposure, we can use spot metering for shooting, and then through the increase or decrease of exposure compensation operation, so as to get a satisfactory work.
4. What is backlighting
Backlight, that is, the lens and the light source look at each other, the middle of the lens and the light source is the shooting subject, the lens -—— subject - the light source these three are in a straight line, that is, backlight shooting. Backlit shooting is the most interesting way of shooting of all light, but also the most difficult to grasp a kind of light, according to the different subjects, backlit shooting, some will form a silhouette, some will outline a beautiful gold edge around the subject, the visual effect is very beautiful.
5. What is side backlighting
The side backlight is in the middle of the side light and the backlight, and the side backlight light source is in the 45 degree position of the straight line backlight, that is to say, 90 degrees is the side light, 45 degrees is the side backlight, and 180 degrees is the backlight. Side backlight is also a very attractive way of shooting, compared to backlight shooting in terms of exposure side backlight is easier to control, side backlight can make the shooting scene appear concave and convex, rich in three-dimensional sense, generally side backlight is used to express tough objects, such as shooting stone houses, stone arch bridges and other objects.
6. What is top light
The top light appears at noon, and the light shines vertically on the top of the subject. In photography, it is generally avoided under top-light conditions, and the top light does not make the subject clearly displayed like the smooth light, nor does it make the subject layered like the side light and the side backlight. The use of top light shooting is only used when expressing a certain picture effect, such as blocking part of the light, letting another part of the light shine down, shining on the subject we want to represent, such a picture composition is very connotative, full of artistic atmosphere.
