I've been experimenting with glycin/metol combinations and getting pretty good results, sharp but a little grainy, high speed (half a stop over Xtol?), nice mid-tones, high lights that don't run away. I recently added some salt per Patrick Ganiers article in Phototechniques and that really helped the grain quite a bit. This combination is pretty good with 35mm TMY, D400, HP5+. 4X5 TMY looks really nice. My last version is: 1 tsp Glycin, 1 tsp Metol, 8 tsp Sodium Sulfite, 4 tsp sodium chloride to make one liter.(posted 8180 days ago)Is anyone here using or have experience with FX2 or TFX2 from Phototographers Formulary or any similar Glycin/Metol combinaton? I've read a few archived posts here about FX2 but I'd like to know more.
