    Sacrifice 10 frames of one roll shooting a grey card at noon, bracketing +5 and -5 stops or their increments and then develop the roll accordingly with the manufacturer (film) instructions.

    That's the only way to fine tune the personal EI based on what you're going to do with the negatives, either scanning it or printing it diffusion versus condenser head, etc...)

    I use Rodinal 1+100 for 17 minutes when exposed at EI25.

    When I've used the taco method in a 120 tank, and agitated by inverting the tank, I'd do 5 gentle inversions at the start of each minute, then one inversion every three minutes. I use the same dilution, timings and method for Efke R25 (120).

    In the Paterson Orbital, I find PC-TEA works well too.

    Try Beutler at EI-40 for 16m semi-stand. Works well.

    I use Efke25 and Rodinal 1:25 as per the Massive Dev Chart in tanks and rollers. Never had a problem with too much contrast. I'm guessing it was exposed incorrectly, definitely do some tests and don't give up, it's a wonderful film that deserves to be used.

    Beutler E.I. 25-32 and Rodinal E.I. 25 are both very good fitting developers for the Efke 25 film.

    That's interesting Adam. I use the same tank, same film, but my Rodinal is 1:50 for 10min @ 20˚C. I generally just use my experience for a light meter, but it could be your shutter or aperture is having issues.

    Last year I switched to Ektar lenses (a Tessar clone) and have been happier ever since. How are you agitating?
    If the lens doesn't read "ZEISS", then it just isn't.

    We process allot of EFKE film, likely more of it than any lab in the US.

    About 75% is for positive dr5 processing. all the EFKE films do very well in our process; http://www.apug.org/gallery/showphot...6&ppuser=17909

    The E25 has no contrast issues unless you push past 25iso [in dr5].

    As a negative, we either use D23-modified or DD-x. Both control the contrast in the negative.

    Let's not make this more complicated than it is

    Adam,

    Carefully consider this before you do anything else.

    You can do this successfully with the materials you have. If you have too much contrast, you developed for too long or agitated too much. That's mainly what determines your negative contrast.

    1. Are you happy with the shadow detail? Yes - keep exposing the film at the same Exposure Index (EI). No - increase or decrease exposure until you have enough shadow detail. You may have to sacrifice a sheet or two to get there.

    2. Now for your midtones and highlights - change your development time until you have contrast in your negatives that is printable.

    No other developer is going to magically get you great negatives if you fail to understand the dynamic above first. Continue to use Rodinal, which is a fine developer for this and any other film.

    All it takes is a little bit of practice. But it does take a little bit of experimentation when you start using a new type of film - changing around is something you want to do as little as possible when you're starting out.

    - Thomas

    A semi-stand for me is a two-legged tripod. I use standard ASA agitation.
