I was a supporter of D-19 (10 mins.) for a long
time. But with the advent of scanning and digital processing, I personally
prefer HC-110 Dil. B for 10 minutes. The lower contrast seems to give me
better scans. I know others still prefer D-19 so you will have to
experiment for yourself.
The other thing to be aware of is stop bath.
At one time I stopped using it and just used water because of problems with
pinholes in the emulsion. Recently I have moved to using it again but
mixed at half strength. I know I'm being anal but I think the stop bath
chemistry is a necessary part of the process.
