It is very similar to Tri-X. For instance, I develop Neopan 400 in
Acutol 1+14 for 8 minutes (20C/68F) for use with a condenser enlarger.
and grade 3 paper. For Tri-X, 8 1/2 in Acutol 1+14 minutes is about
right.

Start with your old Tri-X time and adjust from there.

Would appreciate advice on best current developers for 35mm
Neopan 400 . Been shooting sunny snow scenes with shadows.
