My test bed for film and chemistry evaluation was Minox subminiature
format, where tiny changes in exposure and processing become
immediately apparent even in a 6x8" print (19x magnification).
Pan F is good, but no better than TMax 100 when it comes to grain,
acutance, and mid-range tonalities. It's an older formula emulsion.
TMax 100 took me a while to learn ... I finally figured it out: it
needs a LOT of agitation as it was designed for machine processing,
and the traditional 68 degrees F B&W temperature isn't best suited
for it in most developers. Go to 72-74F and strong agitation, it
comes alive.
Microdol-X is a pretty crummy developer for landscape work, where
detail is very important. It was designed with a lot of grain
dissolver (sodium sulphite) to soften grain for portraiture. I used
to use it for portraiture a lot, stopped using it entirely for
anything else.
Kodak's XTOL, straight or at 1:1 dilution, or the very similar
Paterson FX-50, produces similar grain without loss of acutance, and
better speed to boot. I've used it with Pan F, Agfa APX25 and 100,
TMax 100 and 400, Delta 100 and 400 ... all do well in it.
The best B&W film and processing soup for landscape work I ever used
was Agfa APX25 in 35mm and medium format sizing. Rated at EI 50,
exposed carefully, processed in XTOL 1:1 @74F with very light
agitation, it produces negatives that express gorgeous tonality, are
virtually grainless, and both scan and print in the wet lab well.
Unfortunately, APX25 is now long gone from stores, and Agfa is out of
it. I still have a couple dozen rolls in my freezer (and about 60
rolls of Minopan 25, (which is the factory slit, Minox-branded
version for 8x11 cameras).
