Pc-512 Borax Starting Times - Starting point times for various films with this simple developer

Some of us have been developing various films with PC-512 Borax developer for the last few years and have established some times you can use as a starting point for your own development process with this developer. I will update and maintain this list as other people submit their results.

Please understand that, like any development times, these are a starting point. You may need to fine tune them...

Thanks Karl for this resource page, also thanks to Alan and Andrew. I longed for this and requested also. I missed the post since I could not follow due to my preoccupation.

Karl, can you suggest me starting time for double X? I'll be shooting some in near future. I'll definitely try.

Sorry for the late reply! As a rough starting time, I use XTOL times minus 15-20%. That won’t likely be perfect on the first try, but has always produced negatives that were only needing some refinement and not totally unusable.
