Until now, the best result I got was with the recipe below:
The photo you see below was an experiment to see what happens if we increase the coffee portion in the mixture. I made 30 minutes development because I already observed that there is no over-development but under-development may occur.1 tsp washing soda4 tsp soluble coffee10 drops of lemon juice10 ml CD4 5% solutionWater to make 500 ml
20 minutes development time and 40 ºC temperature
|More coffee leads to loss of color|
The result was not better, I got a darker negative but with less color.
So, by now, the above recipe is the best one.
Meanwhile I am testing some homemade recipes for the bleach-fix bath, because the bleach by-pass is not giving good results.
