    Stop bath & fixer weeks if covered but you'll exhaust them through use first

    Dev I always prefer to mix fresh, even though it may keep over night mines usually exhausted anyway.

    hi tom

    if you use ansco 130 / formulary 130 universal print developer
    it has a HUGE life, as stock, i use it a year old with no problems,
    and it has been suggested that
    it will still be good for weeks sitting in a tray,
    and from i remember ole confirmed this a few years ago
    when he returned from a job, developer left out (for a few weeks) and it was still very good ..
    maybe he can chime in on his experience.

    Ian, how many prints do you make per session and what developer do you use?

    @John, great suggestion, I'll give the form dev a try soon.

    @Anon, know it's not directed to me but as an FYI I make about 10 prints per session. The DR is always dark when not being used.
    I'm not lazy at all but need to be really thirfty these days. Darn kid, his meals, school supplies et. al.

    Thanks All!

    Anything from 10 - 30 fibre based prints per session, but the dev gets absorbed by the paper so the volume goes down, sometimes I need to top up.

    I mainly use ID-78 which is similar to Neutol WA.Ilford Warmtone.

    10 prints, even if large ones, are too little to exhaust the print developer. If you want to save some money, don't leave it in the tray. Put it back in a bottle and you'll get much more prints/l. Also keep in mind that the manufacturers' suggestion about the useful life of the working solution are too pessimistic. From my own tests, I'd say that prints developed in old solutions have slightly less contrast. IDK if there are other side effects, but nothing I could see at that point.

    Oh, developer loss by absorbency is another factor...

    If you're making prints for exhibition, sale etc then it's false economy to re-use developer.

    I use less volume if I know I'm only printing a few images.
