It involves Sodium Sulphite, Phenodin (Ilford) and HC110. Strange brew and it doesn't work all the times. Actual filmspeed is probably around 160, but even that is an improvement over the 25 asa. I will get the formula to you in the next day. Reorganized the office next to the darkroom a while ago and I haven't found anything after that.There is something to be said for keeping everything as a mess, at least it was my mess and i knew where everything was, and the whole thing was my own idea so i cant even blame anyone else!!
