I'm taking a course that involves photography, and most people think you just grab a camera and shoot. No, no, no, there's far more too it than that. You have to know how to set up your shots, how and were to position the camera, measuring of aperature and shutter speed, lighting, depth of field, and plenty of math, among other things.
And I also puppeteer as a hobby. In that sense, I'm still at Elementary level (possibly lower). So much goes into that, as well. Making the character come to life, making it turn a certain way, eye contact, proper lip sync, knowing how to skip syllables and mix up mouth movements when lip synching, moving the character's arm at the same time it speaks without making it look awkward, developing a character, keeping your arm up, staying in place, and so much more.
