My negs are organised... my prints fall into line with everyone else, except Blansky who seems to be semi-organised!
Negs are all sleeved, stored in folders with contact sheet and a printout from my Access DB that I record details in. In this, I record film development data, exposure data, printing data and items of interest (Dates, places, people names). I do need to go thru some earlier negs and add some info and also create some for much older negs that I never recorded anything about. I wish I'd at least written a date on the neg sleeves!
