    old J and C 100 sheet film dev time?

    Hi All, I've dug up my old C1 view camera with the desire to shoot some new negatives for pt/pd. I have a 6 year old box of J and C 100 and see that, unfortunately, they are no longer around. I'm curious if anyone knows a development time for D76? I didn't find it on the Massive dev. chart. I'll likely use a undiluted stock mix.

    Thanks,
    Echard

    Look on the Massive development chart at digital truth site, under unlisted data. I know I've seen J&C pro 100 listed there before.

    Just checked, 9.5 mins for stock and 13.5 for 1+1, both times are 20c temp.

    Good Morning, Echard,

    I can't help precisely with the JC/D-76 combo, but I've found that 7.5 minutes in HC-110B works fine. Maybe you can look at various developing charts for other films to see how D-76 and HC-110B times generally compare to establish a good starting point.

    (That's with continuous agitation drum processing.)

    Hello Echard;
    The old J & C film is Shanghai GP3 100. For D76 straight I would develop for 8 to 9 minutes. This is a good starting point and adjust as needed. Good luck, Steven.
