    there are plenty of people who use it and plenty of examples of work created with it, here on apug or elsewhere ...

    you were directed there in the other thread .. and i will direct you there again

    caffenol can be made with relatively benign household ingredients
    or those found in a grocery store ..
    the chemicals are not nasty and toxic like most other developers
    (pctea/pyro/metol/hq )
    the developer ingredients last a long time both dry and mixed
    caffenol can be used as a deep tank, replenished, or one shot developer
    it can be used as a print or film developer,
    it has no trouble processing a variety of iso films in the same batch
    for the same time


    Blue Monkey -

    if you want to make caffenol with just caffic acid
    there are lots of suppliers worldwide and it is about 1-2$ a kg
    http://www.alibaba.com/showroom/caffeic-acid.html

    but there might be other ingredients in the coffee that add to the developer
    and make it do what it does ... so your results might not be the same ...

    I think mint tea or an infusion of rosemary leaves will work.

    I have only tried Caffenol once (simple version without ascorbic acid) and I thought it was very good. I couldn't tell any difference in the negatives from those I had developed with Ilfor LC-29 which was my normal developer at the time.

    Yeah, I can't imagine who would need a pound of phenidone as a private citizen! I think I bought 100 g from the Formulary about three years ago, and I'll probably be used up before it will.

    It apparently keeps better in solution in propylene glycol than dry; easier to measure that way, too.


    What is so alternative about Coffee developers? Do they produce different results from regular developers?
    Well, they're mild staining developers and have no solvent whatsoever, which is a kind of interesting combination. I've found I really like the results I get from Fomapan 100 in Caffenol C, though I couldn't tell you in objective terms exactly what constitutes "That Look".

    They're "alternative", though, mainly in the sense of being made entirely from household ingredients. I wouldn't really call Caffenol an "alternative process" myself.

    I've read too many problematic Caffenol accounts to consider it poor. That's why I never gave it a try. How much film and how long did it take you to iron the kinks out of it? Is it good with fast films? What about fog and general stain?

    PC-TEA worked for me right away without any fine-tuning or wasting time and film. It gives results similar to Xtol, and along with Xtol is far from toxic. Phenidone isn't metol, and TEA is used in cosmetics.

    As I wrote earlier, I have only used it once and I followed someone's instructions (probably on this forum).

    I developed for half an hour and my first and only film (FP4+) was perfect. I didn't notice any stain and there was no apparent fogging above what I would consider to be a normal base level.

    It was such a success that if I wanted to develop a film and had run out of 'proper' developer, I wouldn't hesitate to use Caffenol.

    bwrules ...
    the main "problems" that happen with caffenol or caffenol C are problems
    from using the wrong ingredients - instead of washing soda people might use baking soda,
    or a different form of soda "crystals" or they don't use vit c powder but something altogether
    different because they were told by someone at a store that " it is the same thing " when it isn't.
    it is one of few developers where exact measurements are not critical ...

    Appreciate all the information and the feedback from your experiences. Thanks also for the chem links. Sources are limited in Canada. The one source I found, Fisher Scientific was selling in bulk quantities. Hopefully ordering the dry chems will avoid the Hazmat fees and hassles of getting the liquids.

    I do intend to try both Caffenol and PC-TEA now knowing the details of both. Just waiting on my shipment of Shanghai 100. I'll likely try a sheet at a time with each developer/time combination and see what works best with the Shanghai.

    btw, off topic, but the Photographica Fair is this May 15th in Woodbridge. Put on by the www.phsc.ca folks. Good source of expired film along with used camera equipment.
