I could prepare with the help of the pH meter, a developer with 10g Sodium Hydroxide plus 30g Sodium bicarbonate and 15g soluble coffee for 1 liter. pH measured = 9,6.
Protocol of the development
Bath | Duration /min. | Temperature / ºC | Obs. |
| CD-4 | 5 | R.T. | Continuous agitation |
| Caffenol X | 13 | 34-30 | Continuous agitation |
| Rinse | 1 | R.T. | 3 times fill |
| Bleach | 3 | R.T. | Continuous agitation |
| Rinse | 1 | R.T. | 3 times fill |
| Fixer | 7 | R.T. | First minute agitation |
| Washing | 30 | R.T. | 3 times fill and then take from tank and leave in water |
| Dry | 90 min. | R.T. |
Results
 |
| Less grain |
 |
| More detail |
Observations:
I used again the bleach and fix method but I prepared a new bleach bath more diluted than the other and acting more time, 3 minutes instead of 2. With this, great part of the yellow spots did not show but still a little in the upper part mainly but spread over the picture too. The development duration could have been 15 minutes or slightly more.
Now, I have to solve the problem of the digitization, the photo above is better than it looks here, I am sure.
