I'm referring to D76 and reasons for using it 1:1 and not straight. The Sulfite will dissolve the silver in your neg putting into solution and redopositing it onto your film. This by the way and coincidentally enough is the same reason you don't replenish. The silver in your developer builds up and is redopositing itself onto all film. This used to happen with my Acufine in the late 60's till I got with the program. We were so hopeful about hc110 when it came out as you could use it like Rodinal. But it never panned out. TMax Developer was an embarrassment and they've fixed it up to something else but nobody I know will touch it. FG7 is OK, easy on additional Sulfite if any. I use Rodinal and am hopeful about Xtol despite very scary quirkyness reports on minimum amounts to mix up per roll or something like that.
