Thanks. Your idea of diluting the Sodium hydroxide makes sense, and I guess is a lot like the "Ansel Adams Dilution" instructions that came in my Windisch kit from Photographer's Formulary. I'm hoping that by Dividing the developer and maybe even increasing the concentration of the Part A while going down with part B, I can get good shadow detail. I'm rating this film at ASA 2. An extra stop of speed would be wonderful. I got a ton of it in a 5 inch roll, and it's pretty amazing stuff. If I limit myself to low contrast scenes, the effect can be really beautiful, amazingly detailed, and completely grainless. I'm trying hard to finish a 4x5 view camera I'm building so it will be easier to experiment with this film. For the time being, I'm cutting and rolling onto 120 spools for my old Rolleiflex.(posted 8164 days ago)Gene
