Managed to snag some ascorbic acid this morning... haven't been able to find any locally for months now. But with some in hand now, resumed my project of shooting some old Kodachrome and developing it in caffenol.

I just fired off 6 frames to test the solution, and the ascorbic acid sure makes a HUGE difference. Without it, the film was dark and muddy, with very little contrast. Took a lot of editing to even get a decent image.

Add the ascorbic acid, and the negatives just pop right off the film base!



Pardon the water spots..... this was just a test run.

Interesting, I did never take this receipt seriously.

Attila did you ever try it?

Which recipe of Caffenol did you use. I have tried several and had variable results. The ascorbic is available from health stores and those that sell bodybuilding nutrition.

My recipe, for now, is:

100ml Washing soda
16ml Ascorbic acid
160ml Coffee
Add water to make 1 liter

(smaller portions can be calculated out)

Develop at 68°F for 15 minutes, rinse with tap water as a stop bath (continue to rinse until water is clear; it comes out very black as a result of the remjet being removed by the washing soda) and fix with Ilford fixer for 5 minutes.
