    How many photographers have access to reasonably clean sea water? Would any of the many pollutants found near shore these days have a deleterious affect on the process?
    WYSIWYG - At least that's my goal.

    A variation on this myth is that sea-water can actually act as a fixer -- that it will dissolve silver halide from film or paper. (I've read this on a few forums.) When challenged, those perpetuating this story claim that they've read about it from reputable sources. One poster on a Flickr forum finally tried it, and found that sea-water did indeed fix film, but the fixing time was over 24 hours (or something like that). I suspect it's simply silver halide complexation by high concentrations of chloride that works in this case.

    Sulfite wouldn't be stable in seawater, which is continually oxygenated. They would react with each other until one or the other is exhausted.

    We did this topic about two months ago...

    It started with a posting of mine. I found over 400 4x5 prints that my father, a Photographers Mate in the Coast Guard 1943-1946, had taken. They were all in perfect condition, despite living in a Florida closet for the last 48 years. In fact, they were in better condition than many of his studio prints from the decade prior.

    I posed the question then, is it possible that this excellent condition could be due to the salt water primary rinse? To some degree, I was jumped on for bringing up an old topic already examined. But the difference is I have proof in my hand, not chemistry research and published papers.

    I"m going to start throwing my fixed prints into the bayou in my back yard.......

    Interesting, I hadn't heard this before. What about with alkaline fixers?

    In the 80's I was worked in Southern Italy, l lived on the cost, less than a block from the ocean. I just put my prints mesh bag and tossed the bag in a small cove for a couple of hours followed by a 5 mint wash in well water. The Adriatic was well know for all kinds of pollution, but 20 years latter all of the prints are holding up.

    Interesting, thanks.

    George - thiosulfate is thiosulfate. It doesn't matter if it is from an alkaline fixer or not. The alkaline fixer will wash faster than non-alkaline.
