FP4+ development in Pyrocat-HD

[Jim Fitzgerald]

I can't seem to find my times for this combo. I have two test sheets of 11x14 that I need to develop in a tray. I will be printing on 11x14 Azo. I need help on the 2:2:100 times. I think I know, and I'm going to DBI these but want to get a starting time. Thanks

I get about 9-10 min. @ 72 degrees for 1:1:100 on 8x10. FP4+ rated at 64, and tray developed.

Sandy King has posted some useful curves for FP4 developed in Pyrocat in this article: http://unblinkingeye.com/Articles/PCat/pcat.html

Thanks, I've have Sandy's article from unblinking eye but it doesn't give times for 2:2:100. I have some 1976 11x14 Azo I'm going to print on.

Paul, thanks that gives me an idea.

Yes, it does. It gives CI and times for 2:2:100 for many different processes and films. Look on the last page. Just find the intersection of the CI you're aiming for and time on the graphs. Look at the Blue channel graphs for Azo.

Colin, you are right. I guess I have to much sawdust on the brain from camera building. Thanks for pointing it out.

Well, 12 minutes and 14 minutes gave me some nice negs. They are drying and I will print them later. Thanks to everyone for their help.
