Thread: Efke IR 820 recommended chemistry?

  1. #1

    Question Efke IR 820 recommended chemistry?

    I have usually processed my Efke IR820 in the school's chemistry but due to an issue with fixer being put in the developer bottle (third time I've heard of this sort of thing happening), I am going to develop it with my own fixer/developer.

    I have D76 and Kodafix (which I believe has a hardener) and was wondering if this will yield positive results.

    Any other input on developers/fixers appreciated.

    Using Efke IR820 Aura, I use ACU-1 1:5 for 8 minutes at 68 degrees f.

    I shoot this film with a Hoya R72 filter at 0.8 ASA to achieve the higher contrast tones I desire. (Yes, ASA 0.8 is not a typo.)

    ...and how do you meter for ISO 0.8 if you don't mine.

    most meters can go down to iso 6 or so, so just count stops(6,3,2,1,.5, etc...)

    please correct if I'm wrong, a tad tired....

    I use D-76 stock and Ilford Rapid Fixer or Hypam. The choice of fixer really shouldn't matter as long as it contains ammonium thiosulphate.

    Cool Re: Efke IR 820 recommended chemistry?

    I have developed this film in Pyrocat-HD and the Ilford fixer with no problems. Actually, I believe that my film was the Maco 820, but I think it is basically the same film with a different name.
