Hello Arie,
I don't have my charts at hand, but I can tell you that a density of around 2.4 measured in blue (do you have a color head with your densitometer ?) on a pyro neg (FP4+) is as dense as a 3.2 non pyro step. In other words, a 2.4 (blue density) pyro neg will print as a 3.2 (normal white light) unstained neg (for FP4+). The stain is very dependant on the film you use. For example, AGFA films hardly stain, ilford FP4+ and PANF are staining strongly.
I have more detailed info. Yo can contact me offlist later.
Philippe

Subject: densitometer and pyro
Hi
I was wondering if someone could give me some hints. I have a B&W
densitometer but I process my negs in PMK. Is there a way I could trick the
densitometer into giving me at least a ball park reading? such as a filter.
If so which one, or can I use a rosco lighting gel? The other option that I
figure is, has anyone calculated a factor that I can multiply my readings
by? By the way the densitometer is a Tobias TBX
Thanks
Arie
