Response to TMax400 in HC110: For the record: I achieved "acceptable" results with TMax 400 in HC110, dilution d, for 6 minutes at 70-71F. Overall the negatives are well- balanced, but perhaps slightly under-developed. I would therefore recommend 6.5 minutes as a starting point for anyone interested in using this film-developer combination for personal film testing. Personally, I'm sticking with Tri-X.(posted 9098 days ago)Asher
