From a physical point of view, the light shining on the surface of an object and the reflection ability of the object itself will affect the brightness of the object itself. For example: a black rag, although the reflection ability of this rag itself is relatively weak, if this rag is placed under strong light, the brightness value of this rag will increase at this time. Practice has proved that the brightness of an object is different under different light. The reason is that due to the influence of subjective light and objective light, the results presented by the subject are different. During the whole shooting process, some factors will affect the brightness value. Therefore, the final effect of the subject will be affected by the brightness value.
