How do you guys have hyper-speed B&W processed? Specifically, who has
mailing addresses of USA labs? I don't trust the drugstore with these;
there very likely to be run through C-41.
Not certain what "hyper-speed" B&W you refer to. The two fastest I'm aware
of are Kodak's TMax P3200 (TMZ) and Ilford's Delta 3200. Both have a
"nominal" ISO 800 rating (Kodak's varies by 1/3-stop depending on
developer). If you use them at an EI faster than their nominal rating,
they are being pushed. Their emulsions were designed and intended
specifically for this, and should be push processed in accordance with the
EI used in exposing the film.
I have used them both at EI 1600 and have them developed "push 1" by a
professional, full-service lab. I don't know of any consumer lab capable
of doing this . . . or willing to . . . nor are most capable of even
understanding what "push 1" means. A full-service pro lab should be able
to push (or pull) process any B&W, C-41 or E-6 film you give
them. Likewise, Kodak (and A&I) should be able to handle pushed K-14
although I would mark it *very* carefully. The remaining film is Scala
200X, and the certified labs for it can push or pull process it. The
mailers from a Florida lab that I have for Scala 200X provide a marking to
indicate push or pull, if it's required.
