Digital BW, The Print

My question would be how to change from Panotomic-X to Tri-X to 
Technical Pan?  That is more than merely a grain issue; it would be a 
spectral sensitivity curve too.

Surely Acufine, D-76 or other developers could be simulated in PS, but 
the film type would be the issue.

Technical Pan (4x5 on a vacuum back process camera) became my mainstay 
for extracting data from faded and/or stained photos I needed to restore.

Absent Tech Pan, which really cannot be simulated in PS, I would not be 
interested.
