All, Im not quite sure why Im on this whim...But here we go: I want to be able to have the option of developing film at anytime, anywhere (que 007 music...). So, what are some formulas that I can make; using items found only at the common grocery store ? Im not even sure if this is really possible....but... Paracetamol could be made using Tylenol tablets, Lye, and _______. I need to find a substitute/source for NaSO3 (Sodium Sulfite). I know of the caffenol recipe too; but I tend to shy away from staining developers. The stopbath can be vinegar. Other suggestions ? As for the fixer, Im at a loss. I think this may be the sand in the gearbox. Thoughts ?
