After reading Alan Ross's report on MG Classic the new paper addresses the few shortfalls of MGIV fiber. News the emulsion will tone with better mid tone separation should increased richness. WooHoo!
With the short image formation time the paper emulsion must have incorporated a developer. Graded will have a longer shelf life.
I'm curious about the shorter untoned wash time. Since the paper weight remains the same as MGIV FB the coating must be different. If so, does that change how one should handle the prints in the wet stage?
