    Take care where we are going with this. Coffee, broccoli, who knows what is next.

    Read Haist. Apparently human urine can be a viable developer. If we go this way, then we will have to specify what the urine producer was drinking and eating in the three hours prior to voiding to generate the feed stock to standardize on development times.

    Then we can really talk up the image in gallery showings.
    I can just imaging the label - "negative and print developed in a solution eveolved from the urine of a pregnant Zulu, who consumed 4 litres of Perrier and ate a package of red licorice during the production period."

    Actually, hats off to your scientific curiousity. Very intersting work.
    my real name, imagine that.

    Maybe the animal the gelatin came from didn't like Broccoli.
    I do use a digital device in my photographic pursuits when necessary.

    Urine with asparagus! The developer could be called Stinkinal-P.

    Ye good olde days, the Saltpeterman made gun powder from urine.

    I'd imagine if we did use urine as a developer, women would have a tougher time filling the film tanks. Also APUGers would have to figure out a standard development time for 98 degrees too. Maybe recycled urine can be the next green, eco friendly photo chemical.

    I don't even want to know what can be used as fixer.
    That aside, this is interesting.

    This is great! It'd be nice to replace the phenidone with something kitchen-derived, but it sounds like there probably aren't any good candidates that would give superadditivity with the broccoli extract. Even as it is, the activity seems pretty low if 30 minutes produced underdeveloped negatives.

    How about a free radical for everyone made a good joke.

    Brian,
    It seems not much research is done on plant extracts.Maybe this is because there are so many ingredients, over 4000 phenolics alone and its hard to patent anything.

    Peter,
    From "Free Radicals in Biology and Medicine" Halliwell & Gutteridge 3rd ed p204,ascorbate scavenges the OH free radical.I believe it would not last long in a plant phenol extract.

    PE,
    The effect seen is the result of scanning a 0.2 in square section of 400 ISO film in a flatbed with a true resolution of 2300 dpi and sharpening hard.
    (I do this because by this means it may turn out to be possible to show on a computer screen the relative granularity from different developers, more work needed.)

    When I get time I will run a check that the Broccoli extract without phenidone is not a good developer,that would be a surprise.

    Thanks for the comments.

    Hmmmmm. I wonder if Broccoli extract affects the green sensitivity of the emulsion....?
