I was following up on a lead for a few extra 4x5 film holders. The man says he'll throw in some old film for free... it could be fun to play around with. It includes a box of 4x5 HIE. "Has it been refrigerated?" I ask breathlessly. "It was until about a year ago."
I could weep......
I could weep......
With sheet film, though you might be able to do some tests and adapt your development accordingly. I have some 4x5 HP4 of unknown vintage which is unusable under normal development but just might be printable with some reducing.
