2 tsp washing soda
2 tsp coffee
45 ml Tetenal Colortec developer mixed with the three components to make 1 liter
40 minutes developing time, semi-stand (1 minute turning every 5 minutes), 40 ºC temperature
And here is what I got:
The negative, again more green but less than former
After positivation with GIMP
After applying an automatic tread called 'normalize' in GIMP
Finaly hand adjust of contrast and luminosity. This time automatic white balance is worst than hand adjust.
Obs.: For me, it is now clear that coffee and CD4 may work together, not competing but completing one each other. In the next experiment, tomorrow, I will increase Tetenal to 60 ml and maintain developing time and temperature in the 40's.
