He is an exceptional photographer from Savannah, Georgia. He exhibited some absolutely gorgeous prints, full of depth, beautiful highs and the shadows were full of detail. He has used nothing buy Tri-x at ISO 200 for years. He processes in D-76, 1:1, 68F for 7 minutes. I have tested it and the negatives are beautiful. I don't think that it will replace my Delta films in Xtol but under some lighting conditions it does have a very appealing appearance.
