    Same here. My SPSE manual has tropical processing but nothing useful for
    cold. This afternoon I am going to the shop to work on the 8x10" enlarger,
    and I have a couple of boxes of books. I will try to find the cold-temp
    processing article I read years ago. If I find it I will post pertinent

    I note that on those pages, it mentions using the developers at 30F, 5F, and
    even below zero temps. Out of curiosity, under what circumstances would one
    need to develope film with chemicals below freezing, and further, what about
    fixing and washing? Are there low temp products for that? And if the answer
    is no, you just use higher temps for fixing and washing, then why not use
    the same higher temps for developing and avoid the possible reticulation?

    This question is part of my "Learn something new everyday" campaign.
    Yesterday I learned something new from an adult website-- wanna know what it

    I don't know that Hurley had to use his developer at -40F/C
    but I imagine it wasn't 68F.
    Details, details ... I imagine using glycols or sea water.
    I've never had to do it, all I know is what is on those two
    pages in the lab index.

    No, I'd rather leave it up to my imagination.

    Sea water is excellent for washing film and prints. Worry about the salt
    deposits later. Or rinse off the salt by peein on the negatives after
    drinking a sixpack of Rice Beer (That's Budweiser). The Bud has no effect on
    the negs, but you don't care as much.

    And, don't forget, you'll get 75% more keepers if you analyze your shots
    after a 6-pack of good Canadian beer...

    It is now time to praise great beer names.
    The award for:
    surging forth against the ravagaes of an onomonpea
    to BLATZ beer, USA.
    blatently not of the German Purity Law (and proud of it)
    to BUDWEISER USA, genetically engineered rice as primary

  10. Thanks for the reference to D8. As for the temperatures that Hurley
    encountered, if you read through the presentation, you will see the
    following (note that he is developing glass plates):

    "Darkroom work rendered extremely difficult by the low temperatures it
    being -13°C outside." The temperature in the darkroom, near the engine
    room, is just above freezing. "Washing [plates] is troublesome as the
    tank must be kept warm or the plates become an enclosure in an ice
    block.... Development is a source of annoyance to the fingers which
    split & crack around the nails in a painful manner."

    I was thinking more along the lines of Molson Canadian, Labatt's, and
    Granville Brewery's golden light ale...
