Hi,

I have been having trouble getting it right with the J&C200 and Rodinal combination.
A couple of weeks ago I ordered a set of 120 rolls of the J&C200 hoping that $1.69 per roll would be enough to make gorgeous negatives.
Agfa Rodinal in higher dilutions has been my choice of developer mainly because it works so well with Efke and Agfa films, plus I like the one-shot formula.
So, I have a lot of Rodinal on the shelf, and a little bit of film that I can't figure out.
My best batch of negs have been exposed at ISO100, then developed in Rodinal 1+50 @ 68*F for 13 minutes. They are still a little dense, but otherwise a good set of tones. It also looks very sharp. Does that mean I have to develop longer?

If your negatives are too dense, you have too much exposure. Try shooting at the rated speed. Too much contrast is a sign of too long a development time. I don't use J&C in roll film (only 4X5 and 5X7), but if it's the same as the sheet film, it's nice stuff.

I process in a Unidrum on a roller. For Rodinal 1:50, I use 8 minutes at 68F, 20% less time than what's listed at The Massive Dev Chart. I haven't tried J&C in a standard inversion type tank, but I routinely knock off 20-30% from published times as a starting point when using a drum on a motor base.

Lets see, looking at my development notes:

Classic200 @E.I. 160 for 12 minutes at 1+50 @ 68deg. Very nice. I agitate for the first 30 seconds, 5 seconds every minute. Full shadow detail, no blown highlights.

The improved Classic 200 we have been selling for the past year is much closer to it's rated speed than the old version which many people shot at 80-100. EI 160 for 11-12 min in Rodinal 1:50 is the right combination.

Thanks guys,

I appreciate your help. Seems like I'm overexposing a tad too much. I'll try the ISO160 and 12 min with 1+50.

I'll let you know how it goes.

Thanks,

JOBO insists that after a five minute presoak, you should use your normal developing times with their rotary processors. I have found this to be a lot of banana oil. My experience coincides with Bob. I start testing at minus 20% and have gone down as far as 30% with some film/dev combos.

mmm Shoot a roll adjusting speed (100, 160, 200, 300) and then develop with Rodinal at your time/temp combination
I guess that'll give you a good idea of what's going on. But from your description you are overexposing and overdelovping.
