For all three of these films in 12x20 and 7x17 my developer of choice is
PMK pyro. Properly handled, the negatives are ideal for Pt/Pd and also
print well on certain variable contrast silver papers. HP5+ is the
lowest contrast of the three with a fairly heavy film base density and a
stubborn shoulder. Useable film speed around 200. FP4+ tends to be very
contrasty, needs to be rated around 32 to 40. BPF is a middle ground,
very adaptable, speed around 64 to 80. The safest approach to processing
these big sheets is to do them one at a time in a tray. Given the number
of sheets you shoot in huge sizes, this is less tedious than it sounds
<s>.
HP5+ also responds well to HC110 developer, especially in a stronger
than normal dilution to raise contrast to Pt/Pd levels. FP4+ seems
tricky and hair-trigger in its response to this developer and probably
does better in D76 or similar. I haven't found a particularly pleasing
"standard" developer for BPF partly because its response to pyro is so
good it hardly seems worth the trouble to find an alternative.
Kodak, btw, *will* supply TXT in these sizes, but you have to order a
very expensive minimum--too rich for my blood though a group order is
always a possibility.
