Jeff,
I hope you will bring some images to OH. Do you make a pin hole in the daylight tanks or is there a certain lens board that they take? I remember you were having trouble with lens boards recently for the new 4x5. Is this a spin off of that complexity?
While you are here I will be happy to show you results from Rollo Pyro. You mix the two parts as needed. I buy two kits of it from Bostick & Sullivan a year. I think they say the kit makes 33 ltr. of developer. Water is the stop bath. I use Ilford fixer at 4 parts water to one part their stuff. Then ten changes of wash water. This does require a Jobo.
Looking forward to your visit. Savannah wants to be sure Eva is coming. Eva is the best apple & stick thrower Savannah (yellow labrador) knows.
