I'm not quite that organized but, I do keep some notes. I have three of the "mead composition" books going all the time.
In one I keep notes pertaining to every film developing session. Everytime I develop film, I note the film, developer, time and temp and a few other notes about dates equipment and subject matter.
I keep notes for each sheet of LF fillm exposed in the second notebook. This includes date, location, subject, camera, lens, camera geometry (if not zero), film, light meter readings, bellows and filter factor calculations, and actual exposure data. Sometimes, I doodle and make a sketch of the scene if I'm waiting for nature to co-operate.
The third notebook stays on the night stand by my bed. I write project ideas and all manner of other mental wanderings in this one.
