I don't believe that this is caused by the pyro itself; I've never heard
of 'bad' pyro. Pyro itself is a single chemical component of many
developers. I've used a number pyro developers, some from the Formulary,
some I've mixed myself. I've had a black spots on prints issue with
Formulary DiXactol, but that may be my fault. In this case the problem does
not seem to have been with the pyro, but, rather, in the way I processed my
film. Since the Formulary distrubutes a number of pyro based developers,
it's important for your lab to give you the name of the specific formula
they used. I'd be suspicious if they refuse to give you this information.
On the other hand, I wouldn't let the lab blame a botched job on 'bad
pyro.' It was their responsibility to test the solutions in the first place.

Subject: Re: pyro processing
it's been processed by a lab.
they have mentioned photographer's formulary to me regarding
print developers but that doesn't necessarily mean the formulary
is their source for pyro.
please tell me whatever you know re: any of the developers.
thanks, marjorie
