Often, you and the director will pick a cameraman from having seen work of his that is right on your mark. “We want what you did on The Duluge.” Often, you both will enter into a tentatinve agreement with a cameraman, holding off permanence until you have seen eye-to-eye on the “look” that is wanted, (Of course, there are some cameramen of reputation or pride or both who will not take anything less than a pay-or-play commitment; “Why throw disce?” would be my reaction to this challenge).
