Semantics.
If you think you're an artist, you're an artist. If you want to be a filmmaker, you're a filmmaker. There's tons of asshole art/film students out there that think because they went to school they're oh so superior to everyone else, and most of them are pissed off that they aren't making millions of dollars because they're so "talented".
I went to art school, but I'm not an asshole. I've run into plenty of them in my travels, though. Case in point, when I told some film school dickhead about my final movie project his first question was "What did you shoot it on?" So I told him 24fps HD video, to which he replied "Oh, well that doesn't make you a filmmaker does it?"
I've never wanted to punch someone so badly in my entire life, that smug little neo-hippie art house fuckhead... Not that I'm bitter or anything, there's no reason to be. I shut him down pretty quickly, because I explained to him in no uncertain terms that there is little if any difference between film and video anymore, and indeed no less than half of the movies being produced now are digital video, and ALL of them are edited in digital suites. (EDIT) I think he just got his widdle nose out of joint because I told him that I'm getting a bunch of grant money to produce a short FILM and the main reason I got it is because I'm shooting in digital video and its a "New Media" grant. Up yours, Shaggy. Go shoot something in 16mm and leave the real filmmaking to the professionals. Welcome to the 21st century. (END EDIT)
Then I fired a few names at him: Robert Rodriguez, Steven Spielberg, George Lucas, Steven Sondheim, ALL SHOOT IN DIGITAL VIDEO. Sondheim is such a proponent he purchased several RED cameras (DROOL) and is encouraging all other filmmakers to use them!
So despite the veneer of smugness "Captain Semantics" tried to keep up, I had rendered his total asshole comment completely toothless. I despise most photography and film students, even though I was one. Education does NOT equal talent, it just means you paid someone to teach you how to be a snobbish little prick. Wait, scratch that. Most of these smacktards were already snobbish little pricks to begin with.
So my point is, don't ever let someone else define what it means for you to be an artist! Its all up to you, and seriously, no matter who it is, fuck 'em if they don't like it.
