    You gotta be kidding me. How does 1+0 waste less solution than 1+1? You trade grain for acutance in the end (less dissolve/re-plate in 1+0). The results are nearly the same.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Another vote for the 1+1 dilution.

    I am not sure what he was saying, but I am guessing that he replenishes. I use 75ml per roll and really love the results with a replenished Xtol system. That is somewhat less than I would be using with 1+1.

    How do different dilutions affect the neg? I use xtol 1+2 with acros - love it. Curious what straight or even 1+1 or 1+3 would do, if anything?
    Diluting a developer such as Xtol, has a slight effect on the characteristics of the film. I have noticed that with HP5+ and TMY, there is slightly more separation in the low density areas of the negative than if you developed Xtol straight. This is more pronounced the more you dilute the developer. Xtol diluted up to 1+3 is the threshold for me. I tested it once at 1+5, and was very disappointed with the results...and the excruciatingly long development time. I should add that I develop in BTZS tubes.

    Also, due to interaction with sulfite and the dissolve->re-plate effect, you will gain "sharpness" at higher dilutions. Of course, grain goes up as well. The thing is that at 1+1, it's almost impossible to detect a difference in grain, especially with XTOL. There's also more leeway with longer times associated with higher dilutions.

    Thanks again guys!

    Sounds like I'm going to use 1+1 or try replenishing the developer. I think I'll start off with 1+1 and take it from there.

    Today I'll be developing FP4+ @ 125 and Efke KB 25 @ 25.

    Is there anything I need to be aware of with these films, or can I find the times in the massive dev chart and use my usual procedure (continuous agitation the first 30s and two inversions every 30s)?

    Will post some shots when I get the negs scanned .

    Sorry for being slow, but here are three pics taken with Efke KB 25 @ 25.

    Fomadon Excel (XTOL) 1+1 for 6mins @ 20*C.
