D-76 1:1 life

[lido]

I am going to develop some film tonight or tomorrow night in D76 for the first time. I've been using Rodinal and T-Max developer until now.

I have 1 roll of TMax 100, 1 roll of TMax 400 and one roll of Tri-X 400. Can I develop all three of these in one litre of D76 1:1? I would do one film at the time as they are all different and require different develpment time. Basically, my question boils down to whether D76 1:1 dilution has enough life in it to do 3 films.

Any help is greatly apreciated.

Hello:

It has been a long time since I used D76 1:1 but it was considered a one shot and high quality developer. I found it so for Plus x. If you have a one reel tank, 330ml per roll should cover most tank reel combos. Why not check with H20?

Since you need from 250ml to 300ml of liquid (depending on what style of tank you use) per roll, you should be okay.

I'd say the problem isn't capacity so much as shelf life.

Assuming you're using a single-roll tank that takes 300ml of solution (fairly typical) I'd think you'd be safer to start with your D76 stock solution and then dilute just enough to do one roll of film; finish it, dump the developer, then dilute another batch for your next roll; and so on.

You'll be using 150ml of stock solution per roll, so if you're starting with 500ml of stock solution, you should have enough to do all three rolls.

The advantage of doing this vs. diluting all of it at once is that if something interrupts you and you have to postpone the other two rolls to the next day, there's less risk of your remaining developer going bad on you.

D 76 is $ 6.99 CAD per (3.8 litre stock sol. ) packet ,at Henry's in Toronto. If the images on those 3 rolls of films are important to you, $6.99 CAD is a good inexpensive investment.I been using D 76 1:1 for over 30 years now, it will always be my #1 standard B&W developer.
