Hollywood production protocol for weddings 

"Give me a cutaway, a reversal, and don’t cross the line.”  Language that makes complete sense to you, right?  How about “Roll sound?” Maybe you’re familiar with that one, where the movie   sound guy is told to start the recorder, and  the slate person places the slate in front of the camera and the AD says “Mark it! “ But I bet you’ve never witnessed it at a wedding.  If you think I’m going to tell you I do all of this at weddings and events, well, no. But I do follow the most intrinsic protocols, the stuff  taught to me many years ago when I was a supernumerary at Pinewood Film Studios in England. I was seventeen and I’d quit school early because I hated school. My initial training started with knowing the difference between emulsion and celluloid, key numbers and reel numbers, how to recognize fogged film, to know what butterflies, HMI's and scrims are and how and when to use them—a training that  lasted ten years, as I worked my way up the ladder, becoming a  film and TV editor, a director of independent art films, before I decided to DP and write. After three decades in the film and TV business i decided that I wanted to be a writer of fiction.   To this day, I get really excited to go out and shoot. For photography,  I typically use 2 cameras, one strapped over each shoulder, so that I can easily switch focal lengths without changing lenses.  For video, I mostly shoot with 3 cameras, plus specialized cameras for aerial or underwater.
