I need some assistance and I am hoping Sandy King might chime in. I am trying to use Pyrocat-HD (1:1:100) @ 21° in BTZS tubes to develop 4x5 FP4+. I am having tests done by The View Camera Store and the initial test for dilution is to develop for 4 minutes.
The problem is that the step wedge is too thin at 4 minutes using the above parameters. I barely have any density at step 11.
In addition to the above params, I used 60ml per tube and no presoak.
* If I am getting an exceptionally thin neg at 4 minutes, does it point to an error on my part or a characteristic of Pyrocat-HD?
* What is the best dilution and/or temp to use Pyrocat-HD with FP4+ in BTZS tubes?
Thank you,
Jim
