    raw ingredients

    The island must have drinking water, tropical, cold, dry, mediterranian, etc climate to get raw ingredients from it. Most uninhabited islands are this because there is no drinking water, so, the short story will have to be a supernatural one, that is an island inhabited but with people who know nothing about photography and have this paradise with, of course, a volcano:
    Hawaii before the arrival of the white men.
    A door is open under certain conditions, it could be atmospheric ones or psycological ones, supernatural ones, but you will have all you need in it.

    Now, an island was considered in having permanent characteristics but see this article
    (Washington, DC) Unusual images of the Earth have occasionally been uncovered after declassification of hundreds of thousands of spy satellite images by the National Imagery Mapping Agency (NIMA). In one of the more spectaular images, gathered on May 25, 2005, the apparent levitation of at least two Caribbean islands above the surface of the ocean was captured (above).

    The islands are located in a large region popularly known as the Bermuda Triangle. The spy satellite imagery clearly shows shadows cast by two of the islands on the ocean surface in such a way that can only be explained if the islands are levitated above the ocean surface, in one case by approximately ten miles
    So if it can levitate, it can do whatever is needed.

    Amusingly I was recently thinking about this lately (who knows why) - but based on some earlier discussion in this thread, can one use urine as a developer for silver-based films or is it just a non-possibility due to the lack of developing agents? I'm not about to drink sodium sulfite or metol. :-)
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    The latter, I think, for most of us. But there's a disorder called alkaptonuria that causes a developing agent related to hydroquinone to be excreted in the urine: see http://www.cmaj.ca/cgi/content/full/172/8/1002, a case study that includes a portrait of the patient developed in his urine.

    The lady of the house has to be a pretty swell sort of person to put up with the annoyance of a photographer.

    If I was on a deserted island I would be too busy looking for a wooden boat to smash up to make a raft.

    Urea breaks down to Ammonia, so that's one source of alkali

    ammonia is also a rather weak silver halide solvent...so in principle it might do for a fixer...mind the gas- it is poisson...

    Hence the old curse - 'May your children piss port wine'.
    George III had it. Could you ask him to accompany you to this island?
    So far nobody has ground a lens - or are we using a pinhole camera?
