    I'm thinking of standardizing my B&W film developing on a two bath soup. There are some great advantages such as: standard dev. time, non critical temperature etc. Anybody here got some advice or want to share experiences?

    Thanks

    Check out Ed Buffaloe's site, www.unblinkingeye.com for an article Ed and I put together on the two part version of D-23. Time, temp and other information for sheet film developing.

    I use homemade Diafine for pushing TX to 1200~1600.
    Not the best dev around, but the best for it.

    I'm uploading to the thechnical gallery a photo of my son using flash, TX and HM Diafine, if you care to take a look.

    I changed to two bath developers about two years ago and have no regrets.
    I get constant good results with Delta 100/ Delta 400 and Fuji acros 100.
    Ialso sometimes use Ilford DDX for Delta 400

    I mix my own and use it for almost all my 35mm and much of my 6x6 work. Part A is 1 Ltr water, 85g Sodium Sulfite and 6.25g Metol. Part B is 12g of Sodium Metaborate in 1 Ltr water. Time and temp are not very critical. About 4 minutes in each - keep it below 80F and you can dump it all after 12 rolls or just replace Part B with fresh. It gives grain similar to D76 1:1 and is N or slightly N-. Great contrast control. -Frank
    My photos are always without all that distracting color ...

    My "Bridge" photo was developed in "divided D23" - really D23 with a borax afterbath. I gave that one 3+3 minutes, since I wanted contraction and compensation for the 17 steps contrast range...

    Thanks you all for your replies. One thing, though, still puzzles me: on the Diafine box it says that dev.times are not critical. So how is it possible to do N/N- development?

    As I'm thinking of mixing my own soups, does anybody know a place in Europe that sells photo chemicals? Here in Holland I can't find a company that can deliver them.

    If you include UK as part of Europe (???), I would have thought Silverprint in London would be able to help. If you refer to mainland Europe. What about Wolfgang Moersch in Germany ?

    Hans, I buy my chamicals from VWR International. Their general home page is http://www.vwr.com, which leads to a lot of national home pages. They have the most user-unfriendly of all search engines, but you will eventually find nearly everything there.

    Diafine has two solutions - A and B.
    Sol. A is the developer and is slightly acid, so there's (almost) no development going on in it (this is very true at 20 C).
    Sol B is alkali+sulphite, and that's where all the development takes place.

    Myths and Facts:

    Diafine IS temperature dependent (not much, but contrast and grain increases with temp. I use it at 20 C).
    Some films are way overated (PX @400 - I did not like it).
    It's an extremelly compensating dev - so if it's a low contrast scene, neg will be flat.

    But TX @1200~1600 gives very good night, artificial light and flash photos (high contrast scenes).
    HP5+ @800 wasn't bad, also.

    If you care, I can post the formula I'm using.
