How to adjust the mirror and aperture under different light intensity

It is not easy to take photos with correct exposure in complex light. This is mainly a problem of photometry, and it is also a problem worthy of in-depth study and research.

First of all, it is necessary to make clear what the focus of shooting is, such as the fallen leaves in the mottled shade. When the contrast between light and dark is particularly large, it is necessary to make it clear whether to shoot bright or dark, or to consider it comprehensively. To shoot bright or dark, you need to use spot metering, set the camera to manual gear, aim the central metering point at bright or dark, and then re-compose and shoot. If you need to measure and consider, choose evaluation metering or other metering methods (the different effects brought by different metering methods need to be familiar with yourself gradually).

If you shoot a portrait, you can put the metering point in the Tang Yin of the character to measure the light. If the light contrast is not great (such as smoothness), you can also choose AV file, TV file or even automatic file.

The only thing I remember is to use the manual stop when the metering point is not in the center under complex light, so as to expose correctly.
