I believe that F76+ is a PQ (Phenidone in place of Metol) developer. I use Clayton F76+ as my daily developer. I also home-brewed and used D76 (and variants) for thirty years or so until a few years ago when I opted for Claytons F76+. I think that Clayton’s gives excellent results (excellent tonality, fine-grain and open-shadow areas) with traditional as well as T-grained films. I find it easier to vary dilutions if I really have a roll that needs more or less contrast (rare). I also find it convenient (as it’s a liquid) and it lasts about three months if stored in tightly sealed containers in a dark, cool place.
I asked because one of the outside pro labs I use, North Coast Photo Service NCPS in Carlsbad,California, uses Clayton D76+.
