I'm a firm believer (or have been led to believe by my teachers) that you need to have still photo skills in order to progress as a motion picture photographer, but I was reading a recent ASC Chat Room discussion by Owen Roizman, who said (sort of) that he wasn't quite sure how important still photo chops should be to a DP. Granted, I don't remember the exact wording of the answer to the question that was posed, but I remember he didn't think it was as important as I've been led to believe. Any thoughts, anyone?
