I do think you missed the point, however. The assumption was how much the processing of Kodachrome damages the environment due to effluents. So the poster suggested processing Kodachrome as black and white film and then use PS to add the missing colors. I thought this was a goofy idea. The poster did not mention any possible environmental impact from processing the film as black and white. For all I know, processing Kodachrome in b/w chemistry might release toxins that are worse than processing Kodachrome as it was designed to be processed. Odd things happen when incompatible chemicals mix. > I always do a full environmental audit before using any camera > equipment - weighting the amount of various wastes by the toxicities > of their individual components.

The deaths in the mines where the thousands of secret ingredients come from? The printed circuit board production, the ink used in the printing of the warranty card? The tanning of the leather? Or the heat that comes from all the hot air generated by "environmentalists" that tell us we are ruining Mother Earth? My God, how far do you need to take your impact study. (smiley) You (and many others) assume the by products are not properly dealt with. We love to read about the toxins, yet we do not know anything past what we are told by loud mouths, and I do not think much of the information we are fed is one bloody bit accurate. Sure toxins are used, but so what? What matters is how they are handled. If you want to do a study, consider how many toxins are used to making everything you love. Your CDs create "problems." Your clothing, food, dinnerware, paper cups, pet food, leather shoes, Hummer polish. Everything you use creates a problem in one form or another. Are you willing to give up your computer, CDs, going to the movies, and living in a house? I also love situational ethics. Oh, Smiley! What amuses me are the Hollywood types trying to save our planet. They want us in tiny wind up mechanical cars; they can use their fleet of limos. Yet they make movies and release CDs. They live in huge homes and they waste everything. > Then I drive into the countryside in my Government subsidized Hummer Hummer? You dastardly cretin. (smiley) I also drive big cars with big V8 engines. Bob â
