How to shoot a feature on Alexa without a focus puller? in Camera Operating Posted February 5, 2018 Hi. Are there many camera operators/dps who do their own focus without the need of a first AC as focus puller? I'm not talking about documentary stuff. I'm thinking about doing it after watching this Listen Up Philip BTS doc. Sean Prince Williams, the DP, is pulling focus himself. What do you guys think when we're talking about working with actors and, sure, with a language that allows some focus mistakes?
