How many photographers can survive in the wilderness? Who are they?

The film crew seems to have five or six people, including directors, photographers, recorders, survival consultants, security personnel, and sometimes some scholars or local tour guides. They all carry safety protection equipment, food and emergency equipment, and many of them ensure their safety. The risk is still high when shooting, but the photographer doesn't have to climb the cliff, but hangs it with a rope. The camera lens can be enlarged and reduced, assisted by off-road vehicles, RV, helicopters and other means of transportation. The scene is real and artificially created.
