Caffenol
8 oz.
Water
2 tsp (level)
Arm & Hammer Washing Soda
4 tsp (slightly rounded) Folger's Coffee Crystals
Mix soda until completely dissolved and solution is clear. Add
coffee, mix until all grittiness is gone and solution is uniform, let
stand 5-10 minutes until microbubbles clear. Use within 30 minutes.
Gives imagewise stain and general (fog) stain.

Note 1: Flow marks; adjustment still required.
Note 2: Very heavy fog, may be untenable combination.
Note 3: Considerable fog, but contrast looks okay.
You can also make Rodinal equivalent with paracetamol (Tylenol).
As per fixer, hypo is generally sold in pool supply stores or
chemistry stores; chlorine clear or something like that,
Cheers

One of the things keeping me from shooting film is the absence of
dedicated chemistry in Saudi as well as the challenge and cost of
shipping them as well. Then a thread on the alt-process forum
popped up about using coffee and a base as a developing agent for
film and paper. A RIT /*article*/
<http://people.rit.edu/andpph/text-coffee.html> explains some
brief research into the process, but lacked the referenced images.
1) Does anyone have experience with this? or have images resulting
from this process to share?
2) I would also need a DIY soup recipe for fixer. Hypo? Can't I
get that from someplace that sells swimming pool supplies?
I'd really like to get a pile of Adox film. My Mamiya has been
collecting dust for about four years now...feeling guilty.
