Fuji Acros and Neopan

Discussion in 'Fuji' started by LR Kalajainen, Nov 22, 2004.

  1. I've been experimenting with Fuji ACROS 100 and Neopan 400 recently as a
    possible alternative to my standard Delta 100 and 400 in the event that
    Ilford actually goes under. I'm getting very nice results with the
    following developer and times.

    For Fuji Acros:

    Shoot at ISO 50
    1 tsp. Sodium Carbonate (washing soda)
    1/2 tsp. Vit. C powder
    4 ml 1% Phenidone
    liter of water
    70 degrees Fahrenheit (21 C.)
    7minutes 15 seconds, two inversions every 30 sec.

    For Neopan 400
    ISO 200
    same developer except substitute 1 tsp. Kodalk (metaborate) in place of
    the carbonate.
    6 minutes 30 seconds

    OK, it's my turn for a stupid question, why do you use different
    accelerators in the two developers?

  3. Not a stupid question at all. There's really no need for different
    accelerators. I do it, because I like to keep my development time in
    the 6-8 minute range instead of a 9-12 minute range. This is because
    I'm easily bored, especially with film developing, and unless Car Talk
    or Mozart's Solemn Vespers is on the radio, I'd just as soon get it over
    with quicker. The carbonate is a more active accelerator than
    metaborate or borax, and with these particular films, it does not give
    me a huge increase in grain size. So, for the slower film, I still have
    the fine grain, but a shorter development time. If you use Kodalk
    (metaborate) with Acros, I'd suggest starting at 10 minutes. That'll
    get you very close.

  4. Ah, però! LR Kalajainen ha scritto due cosette forse interessanti...

    thanks larry for your recipe for my preferite film. But i don't feel ery
    comfortable with your measures, can you *convert* every component in
    metrical to better appreciate your experimenting?

    ciao,
    Stefano

  5. Sure, Stefano. Sorry, I forget that some of the readers of this
    newsgroup are fortunate enough to live in places like bella Italia, and
    don't use the American kitchen measurements of teaspoons and
    tablespoons. (I myself lived in la belle France for nearly ten years.)
    Here are metric equivalents:

    5 grams Kodalk (metaborate) = 1 teaspoon
    6 grams carbonate= 1 teaspoon
    2 grams Vitamin C powder = 1/2 teaspoon
    1 gram Phenidone= 1/2 teaspoon (dissolved in 100 ml 90% alcohol to make
    a 1% solution.

    So, you can substitute these amounts in the formula, and it should work
    fine. Bonne chance!

  7. Changes developer activity. Maybe it's easier to measure. I'm sure one
    could use the very same developer for both films by adjusting
    development time.

  8. One can, indeed. The metaborate formula will process Acros very
    nicely--just takes 10 minutes instead of 7.

    I've tried Neopan400 in original formula(2g sodium carbonate, 1g ascorbic
    acid, 0,2g metol, 0,5l water): 7,5 minutes at 20C(time for D-76 straight).
    Looks very nice.

  10. Did you rate the film at ISO 400 or 200?
    I haven't tried it using metol instead of phenidone, though I do use
    metol in my paper developer.

    I shot it at 400. I don't care much about shadow detail;-).
