I can remember that when I was just beginning to set up my B+W darkroom and looking for film/developer combinations, Ilford gave info on other manufacturers' products but Kodak did not. I would be interested in souping Kodak's infra-red film in Rodinol and maybe using Kodak's HC110 with HP5 if it's more economical. Where can I find starting points for temp/times for these combos?
