The photo above was taken with a Adox Golf 63 at 1/200 and f/8 with Ilford FP4. No software enhancement was applied, just as it came from automatic luminosity of the scanner.
Caffernal looks like a fine grain developer, low contrast and good restitution of the whole grey scale.
In the dilution 1:50 it takes a minimum of 60 minutes to develop at 25ºC.
Now, comparing this developer with the Caffenol C+, using Sodium Hydroxide as alkali too, I found a way to change the properties of Caffernal, I am about to test these possibilities.
The aim of the changes is to make Caffernal faster than it is now. In comparison with Rodinal it is some 4 times slower or more. The contrast can be also pushed a little, I think.
