    Read it twice and think it over tree times.

    Thanks I figured that what happened. the pills are 833% asorbic acid. I am planning to order Asorbic acid. I have to check a local store that may have it. They Should have it since it is a natural food health store. Will get back to you. If not I will order it from Art Craft. I need some other stuff to for my Parodinal expeirement.
    The inversion is what I wondering. I was told not to shake to much. I did 4 inversion every minute. Also has anyone don a stand dev with caffenol?

    Regarding stand development with caffenol-C - yes, I have done it. I basically used half-strength relative to my usual concentrations, and developed for 30 minutes (12 minutes would be more typical for my solution). For agitation I started with 10 seconds (4 or 5 inversions) initially, then just let it sit the remainder of the time.

    The negatives were images of a test target, and they developed just fine. But I can't really say whether I observed any of the usual effects of stand development. This test was an act of desperation really. I just wanted to see if stand development would cure my overdeveloped edges problem. It didn't. So I didn't really look for other effects.

    I use Tmax 100 4X5 and develop according to Reinholds recipes with perfect results in C-C-L stand:

    Soda : 16g/l
    Ascorbic Acid : 10g/l
    KBr : 1g/l
    Instant Coffee : 40g/l

    60 mins @ 20C / 68F
    55 mins @ 21C / 69.8F
    50 mins @ 22C / 71.6F
    45 mins @ 23C / 73.4F
    40 mins @ 24C / 75.2F


    If you use a initial 5 min waterbath, add approx. 10% to the dev. times

    Temps in bold are my usual working temperatures!

    Note : 9 minutes @ 23C, with a 135 film, the film a bit thin, may be a bit more time might be better

    i stand develop rolls and sheets in caffenol. rolls for about 2.5 years (hand tanks), sheets maybe 7 months ( FR tanks ).

    i don't go by strict measurements, and i don't skimp on the ingredients. i don't have a specific order i mix the coffee soda and vit c.
    my results are repeatable and my film looks just fine when i remove them from the black gold.
    i don't have any hang-ups about exact measurements, sometimes they are vitally important, but as i have
    discovered with this developer, exact measurements are not as critical as one may think.

    i also use ansco 130 as a print and film developer. it was what i used for film ( 5 years ) before i started with the coffee ... and like with
    caffenol, i experimented with 130 in a variety of different ways, stand, agitated, rotary, replenished ...
    these days i put " a splash " of stock 130 in my caffenol. i am well aware of how ansco 130 works with outdated film ( its great )
    it contains potas bromide, glycin, soda (as well as other things ) and mixed in caffenol c the 130 boosts contrast a little bit and reduces fog.
    c41, e6, b/w and all asa's ( 25-3200 ) all get processed together for the same time, and they all look lovely,
    i use this concoction as a universal developer with one development time.
    because of the "strength" of my caffenol i don't stand develop for more than 30 minutes
    otherwise my contact printing and enlargement times are too long. the result is a negative with "meat"
    that contact print beautifully and enlarges OK. i could probably use a little farmers once in a while ..


    i recently went through around 4 years worth of film ( spring 2006 - 12/2010 ) they were rolls a mixture of
    stand, rotary processor and agitated in a tank, as well as some sheets shuffled with and without a130.
    i will be posting some of these images in the gallery in the weeks and months to come.
    i have opted not to negative scan them so i get the full effect of the coffee, grain and film base, and prints take time ...

    there is a lot of hype revolving around this developer. many different methods + recipes work and can give repeatable results.


    (added later)

    i forgot to list the films ..

    sheets
    tmx ( 100 ) tmy ( 400 ) and tri x 320 ( tmy + tri x both 4x5 + 5x7 )

    rolls
    b/w tmy, tmx, tmz, tri x, plus x , ilford delta 100+400+3200, , hp5+. panf, efke, foma 100+200+400
    color: fuji sensia 200, astia100, fuji superia400, fuji superia800, fuji press800(npz), and kodak e100g

    i am sure i have missed a few ...

    enjoy your coffee -

    "i stand develop rolls and sheets in caffenol. rolls for about 2.5 years (hand tanks), sheets maybe 7 months ( FR tanks )"


    Wow, that's the longest development time I have ever heard of!

    ...Sorry, I couldn't resist. I am pretty new to developing myself - I think it has been something like a year and a half now since my first roll; all B&W roll film.
