    Seems like my R09 has crystals in it. Does this need to be shaken before mixing. Does something seperate out when it is sitting there for months?

    I had very thin negatives the first time I used R09. Then I changed several things and my latest negatives are far better - they look normal. I changed the following:

    1) I shook the R09 in the bottle before mixing.
    2) I used 1:40 rather than 1:100
    3) I changed the time to 8 min instead of 18 min

    I know, too many changes to be an experiment. However, I wonder if anybody has found that R09 needed shaking before mixing. Or if that was something irrilevent in my changes.

    Thanks.

    I talk to mine. Reacts much better if you don't upset it. And use 1:20 , 1:40, 1:80 instead of the times quoted for Rodinal on the Digitaltruth place @ 1:25, 1:50, 1:100
