    I didn't realize it was that easy.

    Neither did I. It seems that I consume ingredients of film developer every morning with my coffee and OJ.

    it is pretty much the best, least effort developer that exists :smile:
    as long as you get the right ingredients it will work ...
    and the measurements aren't as critical as the
    video-guy said ... i haven't measured anything in almost 6 years

    Quite a well-made video, but doesn't he put the centre column upside down into the tank? The flat part should be on the bottom.

    Thanks for the link; now I have an option to drink the developer if I don't like how the film turns out:D

    What is the "active ingredient" that enables the development?

    And if coffee and vitamin c can develop film, why is normal developer so toxic?

    i'm not scientist, but from what i understand from people in "the know"
    it is the caffic acid in the coffee that developers
    the soda changes the ph ( adds fog too ) and the vit c from what i understand
    increases speed and contrast ...

    reinhold knows way more than me: http://caffenol.blogspot.com/


    it has to be robusta coffee, arabica coffee doesn't have very much ( if any ) caffic acid.
    the robusta coffee is usually the cheap stuff that sells in instant coffee, not in boutique coffee shop.

    if you are interested ( and have a coffee pot! ) i have a bunch of robusta beans ( GREEN! ) and roasted
    that works even better than instant ( for me at least ) ...
    instant is mostly robusta, but still often times is "cut" with arabica so it tastes better ...

    have fun!

    If you soak ground coffee for 12 hours in cold water, then filter it out (1 can of cheap coffee to 12 cups of water is what I use), you get a basic coffee syrup of sorts. If you use good coffee, by all means drink it; it makes great iced coffee, watered down a bit (2 or 3 to 1). If you use cheap coffee, use it as developer.

    Once you add washing soda, all thoughts of drinking the stuff will quickly leave your mind; it smells like the grease trap in a bad diner kitchen. I have had some film come out quite stained, other film seems just a bit less contrasty when viewed in the sleeves than normal. All have printed beautifully.

    I always put the flat part on the bottom. But does it really matter? I don't know.

    yes the column is put in upside down. The Patterson reel has a little stem that will insert into that column and let you spin the reels back and forth instead of rotating the whole tank. Also did you guys catch where he was talking about the film and said 'don't try this at your sister's wedding, use your trusty digital camera', what about your more trusty film camera? :smile: Just saying.

    Ye4s, it does matter. It provides a space underneath the film which allows the developer/fixer to move around when you invert the tank for agitation.

    but bobD
    if you don't have any metol, or sodium sulfite ...
    and just instant coffee ... its impossible to use d23 ...


    caffenol is made from stuff you may have lying around your
    pantry, not stuff in your darkroom cabinet ... :wink:

    ^
    1. I don't have any instant coffee, powdered Vitamin C or washing soda in my house. I could go to a supermarket and buy them.

    2. If I didn't have any sulfite or metol around the house I could order them online and have them delivered to my door.

    Crunching numbers for the above two choices results in:

    1. Getting dressed, going out to my car, driving to market, finding instant coffee, powdered C (if they have any) and washing soda. Getting in line and then paying for it and drving home.

    VS

    2. Ordering sulfite and metol online, waiting for it it arrive, opening front door and picking up the chems.

    Sorry, but D23 still wins as easier. And it still smells better too.

    Now, if I already had instant coffee, powdered vitamin C and washing soda in my house it's true that I could simply use them but only because the effort expended to obtain these ingredients was already expended so it really can't be claimed to be less effort to obtain them.

    And, I suppose one could order instant coffee, powdered vitamin C and washing soda online too which might seem to even out the effort except that lifting them would require more effort than lifting the sulfite and metol, not to mention the greater shipping costs involved with the grocery store ingredients.

    So D23 still wins. :whistling:

    We who mix our own have plenty of fun mixing "real" photo chems from scratch. So, I think you mean "cool" rather than "fun."

    And, "cool" is what also gives us things like Lady Gaga and plastic cameras with crappy lenses that cost $150 and sell like hotcakes to people who think they are "cool."

    So, what I'm trying to say is, you're right. Mixing up caffenol may well be more "cool" than mixing D23, but it's not easier nor more fun. :tongue:

    different strokes for different folks ...

    i've been mixing my own developer from scratch since the 90s :munch:

    i have chems on the shelf to make d23, as well as mortenson's glycin variant and a few others ...
    but haven't had any reason to use them ...
    i roast ( or not this time around ) the beans, shake in the other chemicals
    and use the chemistry for 3-6 months without mixing new ...
    process film and prints in it ... its a pretty easy all purpose universal developer.

    but i can see why folks would say " d23 " or d76 " or "xyz " is better ... its because they are used to it
    and have no reason to switch ...

    i suppose i did miss your point, what was it ?

    to use coffee developers you have to expend energy to purchase the supplies,
    and it takes less effort to wait for metol or sulfite to arrive from artcraft of the formulary?

    it costs a few cents to get coffee c and soda when you are grocery shopping ..
    while shipping charges from the formulary and artcraft are in the dollar amounts ...

    or was it .. caffenol smells bad ?

    yup, it smells bad :whistling:
