DEAR KEN & TIM,
Way back from the mid 70s until I sold my NYC studio and moved to Barbados in
93, I had a 3 1/2 gallon D-76 processing line in a separate film darkroom. As I
went through, literally

I never used replenisher with B&W chems- memories of my high school photography
teacher won't allow it!
But replenishment in C-41 is common for me. In the case of C41 Dev and fix, the
replenisher is the stock solution. However, to make working developer from
stock solution, you add developer starter. So in effect, there is a difference
between the working solution and the replenisher. With fixer, the replenisher
is the stock solution straight up.
For your question, I found this link: [

About halfway down the page is this response: " DK50 and DK50-R Replenisher",
where the poster gives the formulas. I'm not into the actual chemistry, but
there are differences between the developer and replenisher. The replenisher
has 2X Kodak Elon Dev Agent (Metol), 4X Hydroquinone and Kodalk (Sodium
Metaborate), and no Potassium Bromide.

When dealing with D-76 or DK-50, is it really urgent that one use the
replentisher chemistry? Why can't I just use fresh devloper (at the same
dilution) and top up the working developer with, say, 1oz of fresh dev
every use?
