Thomas, I experimented years ago with Tech-Pan with good results. I shot it at ISO 32 and processed it in HC110 dilution "F" for 8 minutes at 77 degrees. ( That's the coldest I could get the water.) The results were good. Grainless 16X20 from 35mm. Negatives were slightly contrasty, but that can be fixed by adjusting dev. time. I can't remember what my agitation was, but I have always agitated fairly gently so I would guess probably 15 sec every minute.(posted 9357 days ago)Randy
