“A shooting session has got a definite shape. It’s like a symphony, you work and build up a rhythm, you get a tempo going and then you relax. (…) You’ve got to learn how to take advantage of the situation; a certain mood and five minutes later it’s gone, so you’ll never be able to take the same picture again. Models are no puppets, they’re human beings and you can’t manipulate them.”
Sam Haskins in The Image (1973).
