So, I've been HIRED to work on a short film project as a freelance position. Only after I was hired did I ask about pay, but it was the first thing I asked when he asked if I had any questions. I have no previous experience with this, so I hope I didn't come off as clueless or obnoxious. He asked how I figured my costs (for freelance), and I just told him this was my first freelance job. I love being able to work on this job, and the experience and exposure will be invaluable to me, but I want to make sure I get paid for this. I don't think that's too demanding... after all, there's been a lot of discussion lately about how artists deserve to be paid for their work and not settle for just "exposure". This is a legit, funded project mind you, albeit low budget. There's nothing sketchy about the project or the people- they're industry professionals.

I don't know, maybe I was too impatient about it, but at least I planted the suggestion there. They say it's unlikely for freelancers to get paid without asking for it first. Any tips from other freelancers, maybe?
