I want to positive develop in pyro because nature , grass lines would be as a relief and may be printed as engraving.
I am using Bolex C8 with Yvar 13mm as a single frame shooter on FOMA 100 R 8mm Double X . I want to develop it with pyro developer reversal.
Is there such a recipe ?
The last comment I mention on using catechol and sodium carbonate as a re-developer, it gives a stain and relief and increased dMax, you need to follow it up with a normal re-developer to max sure all silver halide is developed to completion.
