TriX and HC110 were my choice, too, for just that amount of time, but I
finally borrowed an 8x10, bought some FP4 and souped it in PMK. The negs
look great and I'll report on the prints once I've done them.
I'd like to know, Carl, a bit more about your claim that the pyro "handles
a broader range of subject contrast situations without bothering to change
development times." Does that mean you do fewer expansions and
contractions and just let the film handle it? When would you do a minus or
plus development and when wouldn't you?
More detail would be appreciated.
Thanks,
Bill
