..Hi Don,

I am sure that Sandy will also answer with more details, obviously he is far more knowledgeable since he invented PyrocatHD..;-).. I am also using PyrocatHD as dual negatives ie for silver gelatine and for Kallitypes: I do not run into excissve printing times (I believe around 10 min for Kallitype, but it's hard to compair anyway since we most likely have different set-ups).

One thing which is important with PyrocatHD and JOBO is that you have to run it at the slowest speed available, the faster speeds cause excessive B+F, and thus longer printing times. I use PyrocathHD at 1:1:100, and you at 2:2:100 , so that might help also.

Which film at what speed are you using, and how long do you process in the JOBO (temp?). Which silver gelatine paper (graded or VC)do you use?

Best,

Cor
