My Ideas Are Too Vague!

Isn't that what the premise of a documentary project is supposed to be? Once you start into it, the project will take a direction of it's own. That's what gives your project focus, not planning everything out ahead of time. It's supposed to "document" the journey from Point A to Point B, not focus all the attention on Point B and forget about how you got there. Maybe that's the difference between photography and film. Maybe I had the wrong idea going into this class.
