Regarding Timothy's question--I used to worry about whether I could match up the negs with the notes after the fact, but as long as I have a description of the scene, I can usually distinguish different versions just by looking at the negs and knowing what to expect. A neg developed for +1 will have more contrast than a neg developed for N, and a neg with more exposure will have more shadow detail, and a neg with a smaller aperture will have more DOF. If the differences aren't visible, then something's wrong.
