    Thanks to the help from all you guys (and girls) here on APUG I made what I believe is an Important discovery. Though I've always done everything in my power to produce as sharp a neg possible, I've never been completely, 1000% satisfied. I now believe the cause of my frustration has been grain diffusion (if that's the right term) resulting from sulfite in the developer. Though minutely subtle, there was what appeared to be a micro blur in my photos... almost like there was a piece of the worlds thinnest saran wrap between me and the image. Now I'm talking an extremely subtle blur where the average viewer would never notice... but it drove me crazy! I've been processing tmax with RS and recently F-76 in a Jobo. Very nice negs but missing a definitive clarity! Now I understand firsthand, the give and take with sharp vs smooth grain. I discovered Rodinal (do I hear cheers in the background) with Txp320 using 10 sec agitation each minute. Though the grain is definitely there, I like the clarity. I'd venture to guess d76 1:1 might be half way between with regards to grain sharpness. I will experiment to find out. I don't need the super etched edge effects I thought I might, just a happy medium. I will now run my BTZS tests with TXP320, FP4+,EfkePL100, Bergger 200, and HP5.


    Just wanted to share my excitement and to say Thank you to all you fine folks for sharing your knowledge!

    Bob

    Bob,
    It's good to find someone excited these days. When you finish your testing I would be interested in the results as I'm sure many other would be also. Please keep us posted.

    Hi Bob

    You did a big mistake you did not test XTol. So just take the best!
    Your negs like to get the best, so don't missuse them!

    Glad to hear your images are becoming your vision. Rodinal Rocks!
    Now you see why we monochrome photographers spend endless hours fidgeting and testing developers and films. When you get a match with a film/developer combo, a certain alchemical reaction is formed. By that I mean you suddenly see your images become what you intended all along.
    Good luck and have fun.

    Any of the Phenidone/Ascorbic acid (or ascorbate) formulas (Xtol is one) will give you not only the sharpness you desire, but also much finer grain than Rodinal. Phenidone does not need sulfite as a superadditive or preservative. I get very sharp, almost grainless negs from a simple Phenidone, Vitamin C, sodium metaborate formula.

    When ypu are ready for the next step in the right direction, try Pyrocat HD. Then you will be home.

    If he tries XTol then he will be gone from your grainy soup. Sorry guys!
    And he will make a change for the better!
    But he has to try it and he will never luck back on Rodinal soup!
