RE: TMax 400 in HC110: I've discovered that dilution d is actually 1+9, not 1+39, and that my thermometer was way off (real temp was much higher i.e. about 78 F). A roll of TMax400 in 1+9 at 71 F for 5 minutes was underexposed by about 1.5 stops. I'll try Kodak's recommendation of dilution b (1+7) for 5 minutes at 71F and post the results.(posted 9109 days ago)
