On Semi stand, or EMA or whatever:
I experimented a bit with it (notes are at home, so by heart) I think I used
PyrocatHD 1+1+500 for sure for 1 hour, with vigoures agitation for 2 minutes at
the beginning, and then modest agitation every 15 minutes). On Fomapan 100
there was a definitive adjacent effect, actually too much, so I abounded that
film. I had some ancient EFKE PL100 film left, and that worked quite nice. It
depends on the subject matter, but for architecture I was quite pleased.
Oh and the point is I used vertical tubes filled to the brim with developer, so
in my hands keeping the flim vertical was not needed.
Best,
Cor
