I do 99% sheet film. I have color coded, paper gaffer's tape for emulsions which I affix to both sides of a holder. I record the subject, date, filtration, lens, rated film speed, aperture, shutter speed and zones. If I have a notion about development, I record that. Once I develop the film, I add that little bit of info to the tape, peel it from the holder and stick it on the negative envelope. Never have to transpose, correlate, copy or maintain a log or spreadsheet of the information..it's automatic..
