Is there a difference? I don't know. People believe different things depending on what Planet they're on. I guess I use them interchangeably. Part of me thinks that Cinematographer is proper because out of respect for the Director, there should only be one "Director" on set. On the other hand, I love working with great Gaffers and Best Boys and Grips and "Directing" or leading them - thus, I'd be the Director Of Photography or maybe Director Of Lighting. OK that's it - food for thought.
