Readyloads are fine. Each has a space for writing down notes. But they are a bit more expensive. When the sleeve is pulled out it acts like a sail, magnifying any wind induced movements. So I have been using film holders and individual sheets lately. During a day in a trip I may use up all 12 holders or I may make only one or two exposures.
After each exposure, I write my notes on a paper sticker and stick it across the darkslide. At the end of the day, I unload the negatives into Kodak 50 sheet boxes. When all 50 sheets are used, each of these Kodak boxes leaves 4 small cards behind, making 3 slots between them to store negatives for N, N+1, N+2. Another box stores N-1, N-2, etc. In each slot I put the negatives emulsion side down to avoid scratching by the next negative. Starting from the bottom negative that goes in first I label it negative number 1, 2, and so on in my note book. The paper sticker for that particular negative will be stuck against that negative number in my note book, together with any comments why I want to develop it that way.
All seems well, except that when I get home, I may decide to change a certain negative from N to N+1, say. I then have to dig that negative up from its N slot and put it in the N+1 slot and also transfer all the notes. There is potential for error there.
Or I can just leave that neg where it is, check the accuracy of the labeling as I develop the negatives and take that neg away only when it is next in line.
Has anyone got a better system? Thanks.
