One of my first gaffing jobs out in LA was with Mr. Bennette. His stories were always a personal highlight between setups.
I do like that you note that most do switch between perspectives. I’m still new to all this, so I did an interesting thought experiment (to me, it was, at least). I found that you could use objective framing/ composition with subjective movement within a shot and still get an overall objective perspective of that scene with the bonus of emotionally motivated movement for a hint of empathy.
I hadn’t yet thought of that for some reason (reading user manuals). I’ve done that with cameras but in my [not so] infinite wisdom didn’t think to read the manuals for other systems.
