    I think instant works better just because you can make it more concentrated without doing something like brewing a gallon of coffee and boiling it down. When I tried it, I used an old dusty jar of some instant coffee or other (maybe Nescafe, if I recall) that was in the back of a drawer in our office. Since I generally made espresso in the office, I figured no one would miss it.

    The mention of coffee and tea made me think. Just on a whim, I dumped a tablespoon of ground coffee and half a tablespoon of ascorbic acid in 100 ml of TEA and brewed it in the microwave. Added some to a little cold water (I should have filtered the grounds out) and it eventually blackened a film snip. I doubt it would be any more harmful to the body than coffee, tea and lemon, though that mixture might be rather harmful to the sensibilities. Lemon coffee might develop film with some added alkali.

    Next, maybe I'll throw some Tylenol, C and TEA in a pot and see what happens.

    Regarding robusta and Arabica et al, are we on the cusp of photo developer snobs demanding higher prices for prints from negatives developed in Jamaica Blue Mountain instead of Hill Brothers? Will we find developers made with Ethiopian coffee work best at high altitudes? And what about developer made from those beans that pass through the digestive tract of monkeys -- will they produce an extra-strong stain? The mind reels....

    Probably not. I would guess that reduced silver is reduced silver and it doesn't care what reduces it. I would say that archival status comes from proper fixing and washing.

    Starbucks gives away bags of grounds to gardeners, just ask for them.

    In my experience, using caffenol as a paper developer works almost identically to traditional/commercial developers. Exposure times are virtually the same, and developing times are comparable as well. I tend to mix my caffenol a little strong, so my bath times are typically under a minute. The results, of course can vary widely, from simple staining to surreal blotches and swirls.

    Forgive me for referencing (again... it does seem like tiresome self-promotion :rolleyes: ) my article on the subject:

    Even better, read about it in David Vickers' online mag:
    http://creativeimagemaker.co.uk/
    It's a good site and deserves more traffic.

    That'd most likely have everything brewed out of them, though. What use would that be?

    You'd get negs that are much calmer, less stressed out and don't have to pee every 20 minutes! (sorry couldn't help it)
