I've loved shooting with my new to me Bessa I and just developed two rolls last night. I can't think of a good way to store the negs. Obviously I could put two shots per row and use the normal plastic page I use for 6x6 negs but it just seems like there should be a better way.
Anyone else getting about a 16th of an inch spacing between exposures when using the Bessa I?
I store mine in print file pages in a binder - all 120 film sizes - so that they are easy to view on a light box. Contact sheets are inserted with the negatives just to try and keep everything current and easy to find.
I, too, use the standard 120 roll film plastic pages. I prefer four rows of three negatives each, but I easily fit 2 6x9 negatives -- or two 2.25"x3.25" sheet negatives -- in each row. I keep them in an archival binder (a loose-leaf ring set in a plastic box), and put another plastic holder with the contact sheet and exposure information behind each negative page.
I also store mine in the usual 120 sleeves. I don't mind only having the 2 frames in each row - means I have a full roll on one page. The sleeves I use allow me to print through for contact sheets if I want, rather than having to slip out and load into my 120 contact printer. All filed neatly into a binder for quick reference.
