I've just emerged from a marathon darkroom session...I was working on my back log of tiny format negs from the past three years. I noticed that every time I opened an envelope of Tri-X negs that had been developed in D-23 and exposed in the old Nikon FA...I could be assured of getting an easy print on grade 2. Nothing else was as certain....the cheapie Yashica...lots of variability in results. Some un-printable negs. It was the same with the old spotmatic and the Minoltas - results were all over the place. Same thing when I develop in HC-110...sometimes really good sometimes...really, really bad. I think I should just dump all the other cameras, film and developers and stick with what always works (for me..YMMV ) How 'bout you? Do you have a rock steady winning combination?
