To follow up;(posted 8802 days ago)Scott is developing 35mm HIE in technidol for 16 minutes at 70. He uses a TTL meter setting of 300 and takes exposure readings off a grey card. His images look pretty low contrast for HIE. Hope this idea works on 120 MACO which is NOW available on B&H's web site! Konica 750 is just too high contrasted and nonhalated(new word?)for me.
