I'm interested in ideas and where they come from and try to notice when a new one appears. Late in the week I learned two new things, both of which I needed to know. They weren't grippingly important- one involved building frames, and the other a film processing tip, but both were unencountered new ideas.
Once I get a visual idea I'm interested in pursuing, I work out the details of shooting it in my head and let it morph a few times, then round up the subject matter and set it up. The details shift at every step. For some reason, I have to actually burn a piece of 8X10 film, then immediately I see the next incarnation. Then I shoot that an see the next one. If I can put on the brakes enough to go process film and contact it, then there is another level staring me in the face. Takes about three shooting sessions to get an idea worked out. I'm interested in visual ideas that have never occurred in nature or culture.
