In my first days at Brooks Institute I was given a small piece of paper that told how to notch film holders in roman numerals so the film could be tracked to the info by way of the number. For example a "V" is of course five, and you just had to write five in the notebook and the information after it.
Has anyone here used that process of marking holders? I have my original 4x5 holders that are marked but I haven't done it for my 5x or 8x. I was developing some 8x10 negatives this weekend and keeping track of the films, different lenses, same subject, has been a challenge.
