E-6 Recipe for first developer?? Anybody got one?greenspun.com : LUSENET : Large format photography : One Thread
About 3 years ago I wasted a lot of time and film trying to sidestep the whole E-6 kit thing (pay extra for hazard shipping and then it poops out before you've developed enough cu.in.) by mixing the stuff myself from dry chems.
Obvious benefits are you can batch the stuff to size needed anytime you want, and the dry chems last a LONG time. I had some success BUT never really got the bugs out and eventually gave up. The 1st developer is my bugaboo! Color, bleach and rinse are fairly easy.
Anybody out there fiddling with this? Got anything working REPEATEDLY?
Thanks to anybody brave enough to stick their neck out on this one. Jim

I don't know if this is your problem, but one problem with cutting down a large batch to smaller, whether with liquid or powder, is that the raw chemicals won't be well mixed - regardless of how much you shake and mix. The smaller batches won't have the correct relative amounts of chemicals.
I'm interested in see what comes of the tablets that Tetenal is developing. Don't recall if they were doing E-6. I do know they were doing C-41. It would be nice to have a tablet for one roll of film or a handful of sheets.
