I don't know about TX because I don't use it, but with HP5+ in 35mm format I see a good compromise point at ID-11 2+1 (two parts stock plus one part water) at 20C. Also, with PX I liked ID-11 1+2 (one part stock plus two parts water). I said ID-11 because I prefer it over D-76 (without any significant reason). EKC lists developing time for XTOL for wider range of dilutions but I wonder why people stick with 1+1 and 1+3 with ID-11/D-76 type developers... (maybe the difference is small and people think it's not worth it... right, I'm not claiming that 2+1 will produce dramatic difference compared to 1+1.)(posted 8390 days ago)
