FormulasPat “Gadget” Gainer developed PC-TEA as a simple to make alternative to Kodak’s X-tol.  It’s a one solution, one shot developer. Some folks found it prone to fog, so they experimented with adding Potassium Bromide.  Here’s the version I use.


Triethanolomine heated to about 180F 200 ml
Ascorbic Acid 45 g
Phenidone 1 g
Potassium Bromide 1 g
Triethanolomine to make 500 ml


Gainer said to use it 1:50 with water. Sandy King recommend 1:100 with development times of about 10 minutes with rotary agitation at 72F.
