    Edit: Doh! I just saw your post above mine.

    Is this really what you mean? I've never head of Rodinal used undiluted (or 1+1 if that's what you mean). I've never seen anything more concentrated than 1:25.

    I actually use D-76 1:1 with Acros 100 and I am very happy with the results.

    OK, here are the first preliminary results. I printed test strips at a magnification of 12 (ca. 30*40cm from 35mm). The Beutler film strip had a bit lower contrast and I compensated this by adapting the paper contrast. Not ideal, I know.

    Beutler shows a bit more resolution than Rodinal and XTOL 1+1 (one step in the USAF chart). Rodinal is visibly grainier, XTOL and Beutler roughly the same. Rodinal looks slightly sharper than XTOL, Beutler maybe even a bit more but looks (due to the finer grain) cleaner.

    All in all the differences in grain (except Rodinal) and sharpness are subtle and one has to examine a 30*40 print quite close to see the difference.

    Rodinal had 22°C during development which is counterproductive for fine grain. Other people report that Rodinal at 16°C gives visibly finer grain but not at the level of D76 and friends.
    Regards,

    Not to hijack but can anyone explain the reason that rodinal gives finer grain at slightly lower temps?
    I've seen this mentioned several times and am curious.
