Hey, wombats are cool. Most of my family are...
g'day all, great info, thnx
so, we can replace developer, both film and paper, with coffee and washing soda, can we replace fixer with a common household product?
Ray
Thanks all. Has anyone tried to use coffee and soda crystals as a paper developer for lith prints? If so, please can I have a recipe...I'm using Fomatone FB warmtone paper and looking for a colder effect than that resulting from using LD20 paper developer, perhaps Dektol paper developer added too....thank you
I didn't like the 2# prices for 'Chlor-Out' sodium thiosulfate, so I kept calling pool places until I got a distributor. They happily ordered me a 25# pail despite being a retail customer...it was cheap too...
I'm not so sure coffee developer is any safer than catechol after it's been treated with lye, which I cannot buy at any local store.
whoa, backup Murray
i must admit i'm no techno/chemo junky
what you posted will make usable fixer?
Ray
Lye? I didn't know anyone had coffee developer recipes with lye. I'm using coffee, washing soda, and ascorbic acid (in proportions that I think originally came from Donald Qualls)---the results are OK, albeit pretty grainy with most films, and I'm pretty confident in the low toxicity of the soup. You *could* ingest enough sodium carbonate to be a problem, but it's hard to see why or how anyone *would*.
The low-contrast "Caffenol LC+C" version really shines, IMHO. (I've been using it with Adox ORT 25.)
