The skill of producing porn comes from the cameraman's relationship with a model. He has that gift that put's models at ease and yet still leaves him in command. He knows his stuff, the model knows he knows his stuff. And he's the type of guy that allows her to do the most intimate things with emotions she keeps for very few people. Most good pornographers have or are able to seduce women with charm or cheek. They don't do the job to get laid, they do get laid though.
He knows the angles, poses, settings, etc. But that's easy it can be taught. What has to be learned is the different personalities people have and models are people. In my case is she a mouse or a tiger, a leader or a follower, shy or over confident, and more.
Will she be scared if I look remotley interested in sex, or will it flatter her that I think she's sexy. Will her mood change as she goes threw the scene. Who do I put her with, what will she do, will she flake out, and more.
Because the viewerdemands a believable performance and unless she's been to drama school for 5 years, there's only one way to get a performance that looks believable. She does it for real.
Unlesss for real is timid and surpressed because so far all te sex she's had, including masturbating, was in her bedroom with her parents in the room down the hall.
Porn has never been about film, tape, digital, SD, HD, 3d, VR, 4K, if one has the right lens, lighting, sound, the right colour sofa, etc. It's about raw emotions being shared with an audience of one. Sometimes two.
It's not about poses, it's about the look in the model's eyes that says "Yes I would."
