According to the characteristics of China people's skin, there will also be a piece of paper, which will be adjusted based on the light blue white balance in front of the camera, so that people's skin (especially ruddy face) in the photos will look a little spirited. It is determined that in exposure value, if the light distribution at the shooting site is uniform and the brightness of the person is similar to that of the background, it will also be exposed automatically (focusing on the central average metering). If the average time distribution of the shooting scene is more accurate than automatic exposure, exposure value can be used, and the following three methods can be used: zoning photometry. Second, it is measured when it is used. Third, use 18% grey board.
Using zonal photometry
The pictures taken by the digital camera are divided into certain regular N partitions, and the exposure value of these partitions are measured respectively. The digital camera comprehensively calculates the appropriate exposure value according to these exposure value. This exposure value is actually automatic exposure, which is more accurate than general photometry.
In-service photometric method
There is about 2% partial metering in the center of the photographic picture, and some digital cameras can also use spot metering instead of partial metering. Partial metering, which is about 10% in the center of partial metering's shooting picture, can also correspond to most shooting contents for American photographers. Use spot photometry to measure the time and face of local characters, and get the correct exposure value. If your digital camera measures light by area or spot, and this part is also close to the person being photographed, the face of the person photographed with the digital camera will be locked and returned to exposure value for metering and partial shooting.
