Q: cheapest develop-only rollfilm processing in southern Germany

I've yet to do E-6 myself but the temperature shouldn't be harder than C41, it's actually very easy to keep the temperature between 37.5-38.5C in a kitchen sink filled with water. Basically you start developing when it's cooled down to 38.5C and it won't have gone below 37.5C when the 3-4 minutes developing time has completed. True, except if I understand it correctly you have to maintain that temp for several of the initial chemicals, not just the first developer. Overall a 30 minute or so process. There are systems that you can buy to hold several tanks of chemicals and keep them in a common water bath. There are even water mixers that will mix a stream of hot and cold water to the required temperature in a continuous flow assuring a constant and precise temperature. I have no problem with the mechanics of execution and maintaining the temperature, but I doubt that an economical amount of chemicals would last long enough for me to use them all, consequently the cost would be higher. I only shoot about 20 rolls of 120 per year. And I haven't shot any this year, to date, so that statistic might change. |

There's less latitude with the temperature, and you do need to know the actual temperature of the developer in the tank instead of assuming that if you heat the tank to X then it'll be roughly Y. But it's not difficult, and the temperature is less critical once the development is over. -- Matthew Winn [If replying by mail remove ".invalid" and the "r" from "urk"] |

Get a E-6 chemical kit by Tetenal, Kodak or some other company, and the usual b&w development tools (tank, spirals, etc), a good thermometer, something dark like a cloth film changing bag or the back of your bathroom, follow instructions and there you go.. This is what I'd use, and don't get scared when they say "6 films", that's an error on the fotoimpex.de side, it can actually do 12 according to the manufacturer: http://www.fotoimpex.de/shop/fotoche...dia-filmentwic... If you find you like doing that a lot, then next time get this one:http://www.fotoimpex.de/shop/fotoche...dia-filmentwic... The cost per roll is only slightly more than 1 euro then. I don't have a darkroom to do this and from what I have read this is not so easy. Don't need one. And it is a lot easier than it sounds. |

I used to develop in the bathroom, no problems at all. Nowadays the laundry sink is even better: makes a dandy water jacket to keep temps stable. The chemicals go on top of the washing machine next to it, so do the timers and so on. A film changing bag and bingo: piece of cake. Not hard at all, no need for a dedicated room. Now, an enlarger, that would be a problem... |
