How many times can D76 1+1 be re-used with good results? None. That is, it cannot be re-used. Once it is diluted to 1+1 it should be used one time and then discarded. > And > how much should development time be extended after how many times of usage? > How long can you keep the developer good in terms of months, on the condition > of good storing? Packaged D-76 is somewhat different from the classic published formula, in that it has some preservatives in it, and is more stable in regards to pH. I keeps quite well as a stock solution. Here's what I do. I buy packaged D-76 in half-gallon sizes. I mix a half gallon at a time and decant it into brown-glass pint (16 oz.) bottles. I got my brown glass bottles at an ordinary pharmacy, for a few dollars; however, I've been told that most pharmacies no longer stock these, having switched over almost entirely to plastic. On the good side, I've been re-using the same brown-glass pint bottles for twenty years. Then I simply mix the 16-oz. bottle of stock solution with 16 oz. of water before use. Since I use a quart-sized developing tank, it makes the correct amount. It's a neat and efficient system. --Mike P.S. If you haven't used all four pint bottles of developer within a several-month period, SHOOT MORE.

How many times can D76 > 1+1 be re-used with good results? Zero. Don't reuse diluted developer. You'll get dirt in the solution, the activity will change by some unknown amount. D-76 is cheap, use it diluted then throw it out. > How long can you keep the developer good in terms of > months, on the condition of good storing? The side of the D-76 package and Kodak.com will tell you this info. If you want to be conservative, cut this time in 1/2. tv
Storing and using D76 1+1
G'day folks, I'm working on gathering the stuff I need to develope B&W films, mostly Tri-X and HP5, perhaps Delta (does it matter?) Anyway, since it's what I've always used, I'll go for D76 1+1 and I'm having a hard time deciding what to store it in, how often and long to use it before I get rid of it... I've heard the dark brownish glass flasks are the way to go, only opening it when you use it. How many times can D76 1+1 be re-used with good results? And how much should development time be extended after how many times of usage? How long can you keep the developer good in terms of months, on the condition of good storing? Any comments and experiences are very much appreciated. All the best and greetings from a happy Pentax user, Rod. P.S. I am on no-mail, so you can either write to the list, or mail directly.
