thanks, okay , now i will find out whether that's the one they use.
if so,
is it best to use another pyro or is there just some tweaking of the
method ?
thanks, m

thanks lew, is DiXactol a pyro developer ?
Yes, it is.
my hunch is that it is, as you said, in the incorrect processing of
pyro.
no one has said it's the developer itself but i am guessing that pyro
has to be processed in a particular otherwise it is vulnerable to
black
spots in the printing.
It's *not* the pyro that requires special handling, rather it's this
specific formula: DiXactol.
i just want to verify whether or not incorrect pyro processing can
lead
to black spots in the prints ?
i don't have the problem with color film or with B & W processed by
the same
or by other labs in non pyro developer.
thanks, m

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.

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

Yes, which developer, specifically, are you using?

of the prints.
AND
