Dear Sandy,
Your account has inspired me to borrow a friend's 20X24, for a project I've
been working on, photographing squatter settlements in Manila. I also have a
450mm Nikkor-M and was pleasantly surprised to hear that it covers the
format! I am wondering how wide this lens ends up being on 20X24, something
like a 24mm in 35mm?
How did you process your film? I was thinking of using Rollo-pyro in a Jobo
20X24 print drum, but am concerned about film streaks that I've heard occur
with the big print drums. Given the high cost of the film and the fact that
I only have one film holder, I don't want to lose film in the processing
stage so I'm thinking the safer alternative is a regular non-staining
developer that isn't so streak-sensitive. Its just that the pyro gives me
such delicate tonality in the sky. Anyone's experience developing this
format would be appreciated.
Thanks in advance, Neal
