    Studional / Rodinal Special (Spezial) and APX-100 (35mm)

    I've been all over this forum for some kind of consensus with this combo, without any great success.

    1+15 in 4 minutes
    1+15 in 6 minutes
    1+30 in 6 minutes
    1+31 in 8 minutes

    and many other variations. Digital Truth dev chart has a cpl of the above mentioned too, and I don't see a problem testing for myself, it's not important rolls. But in order to add some truth to this "soup" of variations, anyone who has actual shots scanned and can provide dilution/time data for those shots? What I've found on flickr so far did not impress me at all.

    And regarding the reuse of the mixed soup, do you guys mix the used soup back into unused mixed soup after the first round, and how many tanks do you run on one batch?


    Great thanks!




    Cheers,

    I've developed APX 100 (Sold as Rollei Retro 100) in Studional 1:30 for 7min.
    This is a good starting point with Studional no matter what film type (few exceptions).

    If you wish to reuse the developer, develop at dilution 1:15 and develop films for 3:30min as a starting point.
    I think for every 4 rolls, add 10% to the developing time. However, I have no experience with re-using this stuff, and the compensations involved.

    Hi Felinik - these are the two most important points in your post. I strongly suggest you test yourself. It is impossible to judge the image characteristics and general performance of any developer or film by looking at images in online galleries. It is one of the worst ways to evaluate materials.

    I think I'll try with 1+31 and 8 minutes @20° C for my first tests, and we'll see how that turns out. I have 2 liter accordion plastic bottles which will be perfect for a dilution based on half a 125cc bottle of Rodinal Special then.

    Should I not be happy about this, I have the other half to try with a 1+15 dilution instead.

    I Developed two rolls yesterday, 1+31 and 8 minutes @20-21° C, negatives looks great!

    I poured the 600cc used mix right back to the 1400cc of fresh mix (in a 2000cc accordion bottle), so next tank I develop is probably not going to need any time compensation I assume, as the major part of the developer mix is unused. However the tank after that I probably should compensate with half a minute or so I guess.

    I usually go 1:15 for 6 1/2 mins. but I've never re-used. Good luck!

    I developed a tank with two rolls yesterday using the fresh+used mix, did not compensate with the development time, negatives looks just like the first ones. I guess next batch I'll add half a minute.

    Only oddity was that after the fix, Tetenal Superfix Plus, which I also reuse (~12 rolls), the fix had turned slightly lemon yellow, that's all news to me.... Though I guess it's not a big deal as long as the negatives looks good after the fix (I always inspect after fix).

    And yesterday yet another tank, this time with 3 rolls, in the same mix as the previous one. Now I added 45 seconds, and it looks great still here!
