Got a roll from a guy who's got a brick and is making me be the 1st to screw up an experiment. I didn't find any references here in a quick search.
Kodak Rapid Process Copy Film (cat 175 3151)
I probably screwed up 'cuz I think I calculated an effective iso of about 3 if shooting in daylight. Could be even lower than that, but, I am no mathematician and I sort of started estimating
So, I will try to get out Sunday and do some shooting around. The tech sheet included gives little to go on. It says things like "can be developed in standard b/w developers" well... isn't that special. Do I go for D-76 1:1 for about 13 Minutes at 20C and hope for the best?
I hope someone's shot with this before and has a better plan than mine of picking a reasonable starting point and bracketing 18 over/under (roll of 36) and the above developing and using this roll as a base for the rest of the brick.
