Wellcome to the new address of Caffenolcolor, the blog about the homemade process I am developing step by step, one step in front and two backwards, eheheheh!
The process, that already can use homemade developer where the only special think you need is CD4, a p-phenylenediamine derivative.
2 tsp sodium carbonate, aka washing soda
2 tsp cheap soluble coffee
10 ml of a CD4 5% solution
Water to make 700 ml
Temperature tested: 40 º C; development time: 40 min
Results: weak negative with color shift to green but with all color information., giving acceptable colors but still very grainy. See photos below.
