Depends on what your shooting I guess…if it’s still you should not need to shoot several shots because you should try to visualize it first, try different angles and feel it, think about it, wait for the light etc..and even with moving subjects personally I try to anticipate…sometimes I take another shot just to have a back up neg with a really good shot. But if some think that the machine gun method serves them well, I really couldn’t care less…personally I think it’s silly but it’s their business really. When you try to make everybody feel like you do you usually get frustrated.
