Here is a link to a few of my first Caffenol C developed shots.
So far I am happy with the results. I solved the "foam" problem, with Titrisol's sugestion to mix the washing soda first, and let it settle. Then the Ascorbic acid, then the Coffee. I also changed the agitation pattern from an inversion, to a twist type. I used a Patterson tank that allows the spool to be turned in the tank. I used a +360, -360 deg turn every 30 sec.
Overall I am very happy with the results.
I posted the photos in a new thread, so here is the link:
