How can aerial photography tell if there is fog?

Visually, whitening is fog, and turning gray is haze. Basically, this judgment depends on permeability. Although the visibility is not good on cloudy days, it is very breathable.

In landscape photography, the weather factor can be said to be quite important. In the eyes of many beginners in photography, only the clear sky of Wan Li and the blue sky and white clouds are considered as good weather. However, it is often those extremely bad weather that can produce good works. Fog weather should actually be regarded as a natural disaster. Fog is fatal weather for landscape photography. Because of the low visibility, the photos taken are not clear and the pictures are grainy, so many photographers will never go out to shoot in this weather. However, this does not mean that this weather can't take pictures of the scenery at all. We can just take advantage of the low visibility in foggy days to take pictures by hand.
