Good Sunday morning. I have a one liter bottle of stock which I have used for perhaps twenty or more rolls (of several brands of film) at this writing. As each roll is being developed, I add about 7ml (that would be about 7ml per roll, or per 8x10 equivalent) of fresh stock to the bottle, and return the used developer, as much a will fit, to the stock bottle. I don't know the life of the stock replenished this way, but will probably replace it when it begins to look too muddy. I know I have some references to using Xtol this way; for me it is turning out to be easy and dependable and to yield good results. I develop up to 12 sheets of 4x5 with this solution, adding the appropriate amount of replenisher. I'll gather up the references and send them along. -bill On Sun, Dec 27, 2009 at 8:57 AM, Elias Roustom <elroustom@xxxxxxxxx> wrote: > Hi all, > > Sunday morning... and I'm reading this... but on the offhand chance I got > an answer, and could develop a roll before heading off to church... > > You all missed my question, my fault.
