I am a big fan of that film. I get great results at IE 64 and developped 4' in Ilfotec HC 1:31 at 20°C. I have since switched to Diafine, where I get IE 160 from the film with no noticeable degradation in quality and better acutance. BTW, Diafine is great to control wild highlights :)(posted 8153 days ago)
