Technically, I help other people make movies. The most I've really shot that I have produced and directed is commercials. But I've had some pretty decent experience, and I have physical proof of stuff that I've done.
It's not the best in the world. There are a lot of filmmakers and cinematographers and directors and editors and visual effects guys that blow me out of the water. And I know that. I'm not touting myself as the best in the biz.
But I do pretty well. I can do better work with lighting than a lot of the lower-budget movies that I've seen, and I can do more with less.
I can take criticism. When it's something specific, I think it's useful. If you say to me "wow, what the hell were you thinking putting a magenta filter on a light that's a primary key for no particular reason", I will either hit you with a pillow or shrug, but it will sit in my mind that indeed you see that it looks silly, and I agree.
But when you just say "wow, that sucks" or "well, I'd do it differently", I get no useful information. If I then ask you how you would do it differently, if you say "I don't know, just not as sucky", you deserve the ass kicking that you will get.
Consider yourself warned. My tolerance for asshattery is way down these days.
