I have a box of sheet film made by Fotokemika rated at 100 iso. It expired in 1989, says made in Yugoslavia and from my understanding says was manufactured under license in Germany.
The box is unopened and I have no idea under what conditions it was stored at. I'd like to get a recommendation on starting points for my development. I'm thinking of shooting it at 25 iso and cutting the sheet into a few pieces and developing at different times. I do my developing at a community darkroom and have access to HC-110 and F76. Since I plan on doing this test this weekend, I'm limited to those two developers.
I know Fotokemika made the last of Ekfe film and uses the Adox formula and from what I've read I'd guess the film I have is probably very similar to the film that was recently made. I tray develop, so these are times I pulled off the massive dev chart. For Ekfe 100 6/13.5 min (hc-110dilB/f76) and for Adox CHM 7.25/13.5 min (hc-110dilB/f76). This is at iso 100 and 20C.
I usually use HC-110 so I think if I cut a sheet into 4 strips and develop starting at 6 minutes, and have each other strip a minute or 2 longer each, so either 6, 7, 8, 9, or 6, 8, 10, 12 minutes.
Any suggestions and tips are welcome because I've never done something of this sort before.
Thanks.
