Hey guys,
About 1 month away from starting to develop my own colour (c-41) film, but there is something I'm trying to figure out.
Because of where I live, only the press kits make sense (due to restrictions on shipping chemicals by air), and I was thinking of buying the 2L (its cheaper due to shipping costs here) Tetenal (http://www.freestylephoto.biz/101241-Unicolor-Powder-C-41-Film-Negative-Processing-Kit-2-Liter?cat_id=1001) kit, but the instructions are basically for mixing the entire thing into 1 2Litre solution. I doubt I'll process more than 5 rolls of 120 in a month, so mixing so much chemistry at once would be a big waste as it would most certainly go bad before I could make use of it.
Is there a way to mix enough to produce 500ml of solution and then storing the rest of the powder until needed? I guess I could just divide the contents of each packet into 4 equal parts (how would I measure that though, is it by weight or something :) ), and then use 400ml of water?
Also, is it advisable to store powder chemicals long term?
Hope my question is clear, and thanks for the help!
