It will come to you. Great article, phantasmagoric pictures.
I'm struggling to understand what I'm doing with my picture-taking device; part of me suspects that I take pictures in order to avoid writing, but there's probably more to it than that; I mean, I've been doing it a long time. I remember my first Kodak Instamatic - $10 was a lot of money for a little kid. (Second grade, I think, so I was what, seven?) "Something something light" would be a good description of the conversation I have with myself when I'm taking pictures. (Also, "Pan, hold still!") I'm not a candidate for giving a TED talk anytime soon, which is probably a good thing; those headset microphones look so stupid.
Oh, hey, while I'm snippeting, I'd like to recommend The Old Ways: A Journey on Foot. There's some serious mojo in that book.
