The art of photography is the art of light and shadow. Although the use of natural light for shooting has the advantage of being real and natural, and it can appropriately show the real atmosphere of the scene when shooting, natural light is not perfect. When shooting portrait subjects, we often have the problem of “yin and yang face” or “black face” in the shot due to the problem of the light source. This is because when taking pictures, the light source enters from the side, or hits the obstruction, the face of the person is prone to appear half bright and half dark or underexposed. This situation will result in unsightly lighting on the face of the character, destroy the integrity of the picture, and reduce the look and feel. However, this situation can be avoided. Let’s talk about which methods can eliminate the annoying “yin and yang face” problems.
Because the “yin and yang face” and other problems are mainly caused by the angle of incidence of the light source, the safe solution is to change the position of the light. This kind of change is divided into two kinds, one is to change the position of the character, such as adjusting the head up or down to avoid direct angle. The other is to change the light state, such as avoiding shooting during periods of strong light, or controlling the position of artificial light sources.

This method of changing the light position is more straightforward, but it is not applicable in all scenes. Sometimes, the photographer needs to choose this time period, or the person’s face needs to be in this angle to match the composition, which requires a combination of other methods to solve this problem. The more gentle way is to choose spot metering. Priority is given to ensuring accurate metering of the face of the person, and then based on this, the exposure value is changed according to the state of the face of the person. This method can effectively change the problem of black face in shooting under certain circumstances, and can improve the “yin and yang face” to a certain extent.

If the light source occupies a large proportion in the background image, resulting in a strong light ratio, the previous method may cause the background The overexposure makes the background of the picture lose the sense of hierarchy. When the contrast between a person’s face and the background is great, if the face is taken into account for exposure, the background must be overexposed. If we need both the normal exposure of the background and the normal exposure of the face subject, we need to use the flash to fill the light to balance the effect of the picture. The guide number of the Nikon SB-5000 Speedlite is about 34.5 at 35mm or 55 at 200mm, which can meet the guide number required for normal photo shooting. At the same time, the flash also supports a radio-controlled wireless trigger system. Even under unfavorable shooting conditions, such as bright sunlight, or obstacles hindering light control, the system can effectively perform wireless multiple flash photography to control lighting flexibly. This wireless system allows photographers to arrange lighting for different light incident angles to achieve an ideal fill light effect.
