1. rate Delta 100 at 80-64 to start.(posted 9002 days ago)2. just prior to use, mix 1 part A, 2 parts B, into 100 parts water. Use a syrnge (sp? i.e., a needle) for the small amount of pyro you will be using.
3. agitation cycles are every 15 sec., for 2 sec. as a good starting point.
4. time at 68 deg. good starting point is around 8-9min.
5. use a water stop bath for 1.5 min. (no acetic acid)
6. fix in an alkaline fixer (like F24) for a few minutes.
7. pour the USED developer back in the tank, and agitate every 30 sec. for 2 min. This is what allows the stain to form.
8 wash for at least 20 min.
These are just starting point. You will probably have to dial it in from there.
These data give me a neg which under a typically contrasty scene will print fine with about 50-100c.c.'s of magenta filtration
