    hi mrrred:

    to be honest i don't think it really matters the sort of fixer used ... i was always told to use speed fixer
    mainly because, well, when i learned photo-stuff the teachers used sprint chemistry (speed fixer ), and not old skool hypo ...
    but the more i read and think about it, it seems to matter less and less, and it seems a lot easier to use hypo than speed fixer ( low tech )
    i think you are probably right about the cast, from what i remember whenever i got "it" i just washed the film a little
    more and it went away, not necessarily over fix ... i was just being a parrot to be honest
    " squawk use speed fixer to get rid of the magenta cast, squawk"

    hi rudeofus

    i was more concerned with using the salt to stabilize and then fixing,
    thinking that too much fix or salt or that "stuff" could bleach the film
    or paper as i have always heard (but not experienced) over fixing will do ...

    Would there be a difference between rock or sea salt?

    The real test for complete fixing is to use the Kodak test solution. if residual silver is present this would be shown by a color independent of any film dyes.
    A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.

    The works fixed in salt were not archival the ones survived were stored in complete darkness for the entirety of their exhistance par viewing by dim light
