Some time ago I aquired several boxes of expired photo paper. And I mean expired. We're talking 1930s or '40s expired.
Getting more and more attuned to large(r) format photography - 9x12 cm that is - I have been exposing on photo paper in film holders for a while now.
In the lot of photo papers were a couple of 100 packs of ~6,5 x 9,5 cm sized papers, meant for contact copying of glass plates or roll negatives. I decided to try an experiment. For the following photos I used the old unidentified camera I own which was made for the 120 film format. The camera makes 6x6 cm images. In red safety light I cut the contact copying papers into 6cm and taped them into a strip to finally roll them onto a spool with reused backing paper.
These are some of the first photographs I made with expired photo paper rollfilm in a medium format camera.
All the exposures were made for 2-4 minutes.
I figured the ASA is somewhere at 0,007, which is seven steps below 1 ASA - which conveniently [sic!] is the smallest ASA setting on my light metering app. Meaning I have to count my fingers for exposure times (not including reciprocity failure). Well, I tested, then figured.
