Adox 25 & 50 - Rodinal or D-76

[Mac064]

I have just gone through a few rolls of Adox CHS 25 and 50 120 rollfilm and want now to develop them. This is the first time I have used this film (although I have used Adox 100 and 200 sheet film before which I really like).

I have heard that both Rodinal and D-76 are good developers for Adox 25 and 50 and I have the option of using (bought) Rodinal or (home mixed) D-76. Could anyone suggest the positives (and risks?) of using both developers and suggest which one I should use. I guess I can experiment using both but I do want to be careful not to 'lose' the images as they were taken on vacation abroad.

Also I have heard that agitation should be on the 'minimal' side (is this for both developers) and that I should presoak in cold water for 1-2 minutes?

Welcome any advice and thoughts.

Thanks for your consideration.

both are good choices for those films! grain is superfine either way, you got to test both and several dilutions to check what suits you. i did some prints in fomabrom variant 111 from adox 25 devd in rodinal 1+50 semi stand and they were very nice and rivaling medium format.

I use D-76 or Pyrocat-HD(preferred) and like them both. I prefer Pyro for its tanning property, which toughens the emulsion making it less prone to damage. If you use D-76 you may want to use a hardener in either the stop or fix.

I pre-soak these for a couple of minutes or so in water that is at 20C (same as the developer).

I've used Rodinal and PC-TEA with the Efke films, and my preferred combination is Rodinal 1+100 as per the MDC. As for agitation, I do five inversions at the start of each minute for the first three minutes, then one inversion every three minutes for 17 minutes. Works well for me across a range of lighting conditions, and gives good shadow detail without destroying the highlights.

Water stop bath, & I've not used a hardener, but just taken care when the negatives are wet.

Rodinal 1+50 - 1+100 or Beutler A+B. Both high acutance developers.

My preferable combination of Efke 25 in Beutler 1+1+10 7:00 minutes at 20 C.
