I've used it and it is one of my favorite developers. Very robust, long-scale negatives with fine grain. I've used it mostly with Verichrome Pan, Ilford FP4 and a few rolls of HP5 and find the combinations very nice. Haven't used it with TMAX or Delta films so I can't comment on those combinations.(posted 8773 days ago)It is spectacular with Verichrome Pan. About as close to Edwal Super 20 (my all-time favorite developer, now long discontinued) as you can get with Verichrome Pan. Juicy, meaty, negatives that need a diffusion enlarger and long-scale, grade 1 to 2 paper for total tonal reproduction.
