Hello,
Yesterday I mixed a gallon of Microphen and a gallon of D-76... The Microphen box indicates replenishing it with 50ml of Microphen stock for every developed roll... I put a liter of it apart in an amber glass bottle, for stock development that way... I never did it this way before, only 1+1, 1+2 or just reusing stock adding a bit of time to the last of the ten rolls per liter...
That made me remember once I read (maybe Ian Grant?) D-76 can be for some time replenished with D-76 instead of D-76R, but the system will collapse after some time if I remember well... So I put a liter of D-76 apart too, to try that for the first time: I can`t make the D-76R... I don't need the system to last for long...
Optimal -Kodak words- is the use of 240ml for each roll, so I plan to use that liter of D-76 for four rolls, but here's my question: how much stock D-76 should I add after developing each of the four rolls? I feel no adding it wouldn't be right...
And for how long would the system work?
With my tank I need 400ml for a 35mm roll and 600ml for a 120 roll, so this way I would't waste as much D-76 as if I simply discarded the stock solution after each developed roll...
Thanks!
