My filing system:
I will try to keep work prints if I am particularly pleased with the photograph I've made, so I don't have a lot of those, lol......I do not keep test strips. Negative filing: I Store my 4x5 negatives in a Printfile sheet, 4 negatives to a sheet. I simply number each sheet.......#1 and #2 the top two sleeves and #3 and #4 the bottom two sleeves. On the corner of each sleeve is placed a little white sticker where I indicate the date the negative was made and the development given, i.e., N, +1, -1, etc.. Each Printfile sheet is simply numbered and placed in a 3-ring binder, the sheets are in descending order. Work print/final print filing: The border of a work print is where I indicate where the negative is found and the date it's printed, ex: #5-3 (1-29-23)........that's Printfile sheet #5, 3rd sleeve; also I will indicate the toning i.e., selenium 1:10, 5 min. I place any work prints I wish to keep in a separate folder along with printing notes (enlarger height, base exposure, and dodge and burn notes, etc....) , the folder is noted with a short title, date printed, and the same negative location info.
This system helps me feel a bit organized as I participate in the hobby; it helps me to reflect. I enjoy seeing how I progressed with the printing from first unmanipulated work print to the final print.
