    Does anyone have practical experience and times for stand developing Efke 25 sheet film in Rodinal?
    Thanks!

    Dilute 1:200, prewash 5 minutes, leave the film in for 90 minutes without agitation. If you feel the need to change anything, remember that it takes a lot more time to make a very small difference.
    But FX-2 is much better for stand development...

    I've tried it with some 9x12cm sheet film.

    I tried for 45min and 60min - the 60 min had better contrast, but I suppose it depends on the scene as well.

    Perhaps try a couple of tests - 60 and 90 minutes and see which one you like best. I have also seen much longer times mentioned.

    Let us know how you get on.

    My routine with Efke 25 (4x5) and Rodinal is:

    1) 4-5 min. presoak
    2) 1:100 dilution 68F
    3) I use J&C dev tube, so I agitate lightly the first 30 seconds by rolling the tube in water bath.
    4) Stand dev for about 40- 45 minutes with a couple of light agitations (10 sec)during the first 10-15 minutes. I've even left it in for more than an hour without much difference (I suppose the developer exhausts after a bit).
    5) I use no acid bath, only water (I've been burned by my stop before with Efke)
    6) Handle with care...I tend to scratch my sheets of Efke more than any other emulsion.
