Dev. of J&C100 and FP4+

[Tammyk]

If you don't mind to answer the question once again, can someone please offer a suggestion for both J&CPro100 and FP4+ sheet film development times using 2+2+100 pyrocat-HD?

I know it's been hashed about, but I've lost the thread and can't seem to find it doing a search.

For FP4+, I seem to recall 11 mins @20C at box speed, but somehow, I think I've used 7 mins in the past and had good results, but I can't seem to remember. A good notebook would likely be in order....

I am new to J&C100. I hope to use the negs for contact prints to VC papers, as well as some alt processes.

Thanks!
-Tammy

Tammy,

if you cant find the info here look on the unblinkingeye.com there is a lot of info that Sandy King has written and posted there on pyrocat hd. look in the articles section about pyro there are some charts and graphs that will help you get to a development time for fp4 and jandc 200

Times

Tammyk-try around 6-6:30 with the 2:2:100 @ 68 degrees for the PL100. I don't think the FP4 will be all that much different. Make some test negatives then soup them for increments starting at this time and you will nail it right away.
Good luck!
