Adjusting development for temperature
wrote in message
news:65b348fd-1314-4287-a185- Hi, JJS. Did you have any recommendations for cold water processing? A check of the Manual I have shows no specific cold water formulations. However, it did list a tropical developer that can be used to 32 deg C, useful for when summer comes. 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 info. |

That D8 developer is some powerful stuff! 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 was?! |

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.

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. |

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." |
