Hi... I tried developing the Efke IR 820 today... First 11 minutes in Tetenal Ultrafin Plus 1+20 That wasn’t it... Seriously underexposed... Tetenal Ultrafin is quite different from Tetenal Ultrafin Plus, isn’t it... Scoured the internet... Ah... The Macophot UP 100 is similar to the Maco IR 820c, and that in turn is similar to the Efke IR 820... Attempt number 2: 4 minutes 30 seconds in Tetenal Ultrafin Plus 1+4... still underdeveloped... besides, there’s hardly any Ultrafin left (I wanted to stick to just one developer in future) so then the question is, are the times the efke IR 820 needs to be bathed in Rodinal at 1+25 or 1+50 known ??!?

Hi Sigrid, What filter and f-stop did you use? Thanks, best regards Steffen

Hello Sigrid, Which filter and ISO setting did you use? Thanks, best regards, Steffen

With a Heliopan IR 715nm filter and the external light meter (Gossen Lunasix III) set to ISO 3 / 6 ... but it’s still advisable to take two shots, one with a setting 1/3 higher and one 1/3 lower Test shot: http://www.fotocommunity.de/pc/pc/display/13660829 Sigrid
