I have seen many David Attenborough's documentaries on animals and birds. The kind of shoots that they do in North Pole or under water or in deep forests on mountains - it seems like their team must spend a lot of time to do it.
How do they stay steady for such shoots. I mean they must eat or sleep. They shoot so close to animals even at night, and it still does not disturb them at all.
The commentaries given by David are so detailed. He describes the behavior of fishes as if he is absolutely sure what the fish is thinking. I mean is it that precise? I sometimes find it unreal but he has been doing this for so long.
