What should I pay attention to when taking outdoor photos?

Is it a safety theme or a photography theme?

Safety means don't fall into the water and go down the mountain, don't fantasize about too many close-ups, pay attention to poisonous insects, poisonous snakes and dangerous plants (stinging and poisonous), don't crowd in front of people, and don't go up and down the valley when it rains (unless necessary, you don't need to go into the mountain in bad weather conditions).

There are no absolute parameters and standards depending on the situation at that time, but the lens cover should be equipped with digital cameras, memory cards, batteries and electricity, and the film machine should be equipped with enough negatives, film boxes, shelves and peripherals, which is the basic principle that will never change. I don't necessarily like what others like. There are too many examples of a failed operation bringing good photos.
