    So that madness of letting water into arid areas for farming is a global malaise. Wonder if I should be thrilled to know or apprehensive!!

    Bwahaha. That just made my day!(out here, fights between state govt over water have been quite timely and about as routine as the monsoons)

    Hmm. I think it's something to do with a more modern way of living where we don't really pay the full costs and most of it is hidden.

    Very true. Recent and interesting read for me was "The Ripple Affect." An eye opener.
    WYSIWYG - At least that's my goal.

    that's it.

    apparently the chemistry/water interchanging is best at 20-21 degrees, so it won't help to raise the temperature..
    (or lower it)

    this is the "washing maschine" principle. it is rather quick - it saves a LOT of water and it works (for me..)

    More film washing

    In the days of hardening hypo fixers and before HCA Kodak literature for its Brownie and other rollfilms stated that if running water is not available, five changes of water five minutes each with agitation is sufficient. A 1930 Ilford manual stated 7 to 8 changes, 5 mimutes each with agitation, if water is short. Leica manual 1930s suggested 8 changes, 2 minutes each, vigorous agitation, if water is short. ( if you own Niagara Falls, all give the usual 20-30 minute running water spiel). Water is always short these days, and if not don't try to make it that way. Anyway, do these archaic methods hold true today if hardening fix is used? With nonhardening fixers would these be more surefire than the surprisingly fast Ilford method of today of only three changes?

    Sigh. When that running water goes down the drain, it doesn't leave the planet, it goes back into the rivers/ocean after being treated. Just let it run. If you think you're saving something or other by emptying and refilling, and that makes you feel good, by all means do that. I'm not sure I would follow 1930's literature for 2014 films though. Depends on which films you're using of course. You will be washing Tri-X a while to get that purple out.

    Yes, these methods are applicable today. I frequently use 5 changes in five minutes, and have done so for more than 70 years.

    Oh, well I've heard of a gravity crisis. Because of what I've heard on this, I've moved all my belongings to the lowest shelves or on the floor, so as to use less of it.
