How are some documentaries about snakes filmed? Especially when snakes are preying, they can also be photographed in caves! I don't understand ~

The basic principle is to wait for the opportunity.

Common shooting methods:

1, long-distance telephoto shooting;

2. Close-range macro shooting (remote control camouflage equipment);

3. Camouflaged wireless shooting (disposable miniature wireless cameras are hidden on snake prey and cast near the snake cave);

4.3D animation synthesis;
