    I've got some Calbe R09 than is four years out of date and has been open for a year. Works lovely I tell you!

    According to Freestyle, dilution of Compard RO9 is 1:25 or 1:50. The older version formula that they sell goes all the way to 1:200 or 1:400. I thought the stuff everyone raves about had the higher dilution ratio. Confused

    Agfa always recommended 1+25 or 1+50 dilution of Rodinal and thatn hasn't changed since the mid 1960's. People use higher diliutions like 1+100 or higher but those were never Agfa's recommendations (in Europe) anyway.

    The reality is that the original dilutions for Rodinal were once in the region 1+5 to 1+20 but that was when negatives were processed to much higher densities and contrasts, and it was used as a paper developer as well.

    If I am not mistaken, Calbe 09 = ADOLUX® APH 09 which can hold up to 50 years.

    Back in the days before Calbe 09 / ADOLUX® APH 09 was reformulated for 1:50, on the bottle it said 1:40.
    So these days both versions of Rodinal are 1:25, 1:50 etc

    Yep, for most general purpose films, 1+50 should do just fine.
    Instead of 1+100, folks should try dev @ low temps 18°C or so.

    So basically, Compard R09 is exactly like my Agfa Rodinal, so not to worry, and the Adox/Orwo is an older formulation which is just as good albeit different (with similar contrast, tones and grain?)

    It just comes off as arguing over something that the average public couldn't give a damn about anymore. I can't imagine having the real name will guarantee a significant portion of "market share."
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    You got it in one.

    As for keeping qualities, I have always found that what the manufacturer says and what I get in reality are vastly different. Almost without exception, chemicals last a lot longer than the makers say they do.
