Following the demise of Kodak-packaged D-76R I thought I would need to find some other developer - or simply go back to D-76 1:1. Recently I discovered Freestyle Legacy L76R but didn't trust that it was anywhere near the same as D-76R. After several conversations with the tech department at Freestyle I was told the Legacy L76R is identical to D-76R and should be used exactly as the Kodak instructions indicate. After the first 90 rolls - my usual dumping point with a gallon of stock D-76 that had been replenished - I'm not as happy as I thought I might be. The L76R replenished D-76 seemed to lose its potency after the first 50 rolls - way before the same D-76 would when I replenished with the original D-76R. I'm a high volume user so all of this took place over about 4 weeks so there is no issue with the replenished stuff getting "old".
And so I find myself back to square one. In this recent experience the Freestyle replenisher is not behaving like the original and while its something I'd like to avoid I think its time I moved toward mixing my own "real" D-76R from scratch. Can anyone confirm the formula in The Darkroom Cookbook (formula #25) is authentic to the original? Are there alternates?
My thanks to all, this is an amazing resource!
