Thanks for your comments on the Nuarc-I've been loking for one in the Maryland area for awhile-just missed one being tossed out in DE by two days!! (light table with it too) What a shame. Anyway, I use the fstop timing method in my darkroom and love it. I have a tape that reads out stops and third stops since I can't use one of your timers with my D2. Can the Nuarc be set up with your fstop timer?
