I have recently found my love in medium format for Fuji Neopan 400 developed in xtol 1:1. Unfortunately, Fuji doesn't make it in 4x5. Actually, just recently I found out that Neopan 400 is a traditional emulsion. I had no idea. I had always figured it was a modern emulsion based on Acros. Anyway.. does anyone know which current 400 speed 4x5 emulsion (HP5, Tri-x, Tmax 400) behaves most similar to Fuji Neopan 400?
