    That's a personal opinion rather than a matter of proven fact I take it? It's getting a bit like P.net on some of these threads LOL

    Well, I have used Acutol and a number of other concentrated/acutance developers including Rodinal, Neofin Blau and Rot, FR-X22, TEC, ACU-1, Ultrafin, as well as other developers from Paterson, and nothing matches Acutol overall. Better tonality, finer grain, better shadow detail, better sharpness. The only developer that even approaches it is paterson FX-39, and that works well only with Ilford Delta films, for which it was designed. Rodinal is a 'cult' developer whose reputation far exceeds its performance.

    Well, the differences were observable enough that Leica Fotografie magazine was able to see them too. I can send the article they ran to you in pdf form.

    Here is a result of significant interest:

    Kodak Tri-X Pan 27 DIN (sharpness high to very high)

    Developer --- DIN speed ---- deviation from average resolution -- graininess
    Acufine--------30 --------------------------------------------------3
    D-76-----------30 ------------------------------------------------ 3
    Diafine---------30 ------------------------------------------------ 3
    Microdol-X-----27 ------------------------------------------------ 2-3
    Rodinal1+50----30 ---------------- lower---------------------------3
    Ultrafin1+15----30 ------------------------------------------------ 2-3

    So, despite its reputation, Rodinal actually produces LOWER resolution than the average developer with fast films! As expected, Microdol-X produces less speed, but of course the graininess is lessened too. With several other fast films (discontinued since the Leica survey) resolution and speed were lower with Rodinal.

    Leica would be the one to conduct such a survey. BTW, how is the efficiency of a developer measured? And how is the graininess measured?

    Data? Where? Certainly not in this table!

    The Rodinal Militia will not accept such blasphemy!

    The almighty God, Rodinal will punish you heathen hordes on the final day of Armageddon!
    May the justice be done!

    We are but slaves of the One, Rodinal.

    Finer grain is not always the goal. If it was I'd gladly shoot larger formats or digital for everything.

    I'm curious about this reported survey -- is this the Leica Fotografie test from the late 1960's? I know Erwin Puts was singing the praises of Rodinal for low-speed films in that very magazine just in the past couple of years....

    Hans - well if the Leica Fotografie magazine says so who are we to argue as simple blind photographers. The bottom line is that photography is our own art, pass-time, hobby, pleasure whatever and we use the materials that we like because it is our own. Surveys abound but bottom line is that it is a matter of personal perspective and to many of us it is the soup of our choice that gives us the look we want. If we all followed the magazines like sheep and only used what they said we should, this forum would not exist and we would all be shooting digital. For my pictures the salt and pepper grain together with sharp pictures is a joy to behold and Rodinal will the my choice for as long as Agfa continue to market it.

    Morten - thank you my friend I wondered what you would reply and you made me laugh so much as always Btw the Rodinal single malt scotch coloured T-shirts are purchased and mine will be printed this week. Long live the revolution ... long live the Rodinal !!!

    Well, I figured since my last supply order from Adorama was pushing $200, that a few more for a jar of Rodinal wouldn't hurt.

    It can hang out with my 18 month old jug of dark amber Diafine and mock my D-76.
