As I do use PMK, I would rather like to comment on using Tri-X/HP5+/TMY at 400 to 1600.(posted 8947 days ago)To me seems like the old emulsions TriX/HP5+ are better for pushing. I fairly often pushed Tri-X to 1600. (Even 3200 can be done)Using DD-X, which is similar to Microphen. I use Tri-X at 400 to 1600 for portraits or when ever I feel the need for a nice grain structure.(New emulsions look almost grainless at 8*10'')
What I did not like was TMY pushed 2 stops in Xtol simply grainy, too grainy for my taste (marriage picture in the church).For 400 and fine detail I use Delta 400 in Xtol 1:1.
I was not really happy with my results for HP5+ in Xtol. So maybe I should have tried Microphen.
Kind regards,
