I am curious to try Pat Gainers vitamin c developers, and have read all the stuff on Unblinking Eye. Where can I get a reprint of his article “The Role of Antifreeze in Photographic Science” in Photo Techniques Magazine of March/April 2004.?
My mext question is about propylene glycol. I realize it is less toxic than ethylene glycol, but at the amounts used I can't imagine that ethylene glycol could be all that bad, as long as you don't drink it.If I read Unblinking Eye correctly, the stock soution is diluted 1:50 prior to use, so by my math, with my tanks, that means 10cc of ethylene glycol for each tank. It certainly sounds pretty insignificant to me, or am I missing something?
