Donald Rumsfeld had a lot of bad ideas, but one of his good ones was the concept of "unknown unknowns" and so forth. This is from a conceptual framework for describing the four stages of learning. One progresses from unconscious incompetency (you don't know what you don't know), to conscious incompetency (you know how clueless you are), conscious competency (you know what those camera controls do, but you have to think about them all the time), and finally, unconscious competency (you're in the zone).
I just got a serious digital recorder, an M-Audio Microtrack 24/96. I've been pondering whether I'm capable of making the shift to video, and I recognize that at least half the battle with video is mastering sound. Last night I took the recorder to my neighborhood contra dance, captured some sound, and combined it with the photographs I took last night, and made an audio slideshow. It's a rough first attempt forged from the heart of level 1 of the learning cycle. I have a long ways to go, and my aspirations far exceed my capabilities right now. But I'm starting.
