How to take good photos in foggy days?

Fog is made up of many tiny water droplets, which can reflect a lot of scattered light. The farther the distance, the more scattered light. The brighter you look, the less you can see the distant scenery. Therefore, the scenery under the fog can clearly distinguish the foreground, the middle scene and the distant view, and strengthen the sense of depth of the space; Moreover, fog can also give people a dreamy feeling, which can cover up the chaotic parts in many environments, make the theme more prominent and the picture more expressive. When shooting fog scenes, I always pay attention to the following points: exposed to fog, the whole world is white. The camera's automatic metering system is easily deceived by the environment. According to the environment at that time, the exposure 1-2 can be increased. Pay attention to check the histogram of the photo when shooting to ensure that the curve does not overflow. It is also convenient for later adjustment.
