RE: Some Kallitype observations
Thanks for clarification. What if I add dichromate beforehand? Will it
cause the developer go bad in the long term? I guess you do it for being
able to print with negatives of different DRs; because it lets you mix
developers with different dichromate levels, as needed. Since I will be
using calibrated digital negatives, I guess preparing a dichromate-added
developer stock solution beforehand would not harm... Is it so?

Sorry, my head was somewhere else. What I meant to write was that I
replenish the developer at the rate of about 50-100 ml of fresh
sensitizer for about every 100 square inches of print surface that
goes through it.
I keep a bottle of fresh developer on hand (without dichromate), and
a small bottle of 5% dichromate. Since I use the dichromate at 2ml of
the 5% solution per liter of developer, when I add 100 ml of fresh
solution I also add 4 drops of the dichromate, assuming that 1ml is
20 drops. Hope this is clear.
