    no this is backwards. Diluted takes longer.

    Oops - polyglot has it right. Thanks!

    I've added a correction to the original post.

    I hate that Kodak used the colon. The plus, which Ilford uses, is unambiguous. The colon is not.

    This often gets me confused too, and it's really nutty that something so simple somehow got so fuzzy. In my mind, it should be "full strength", then 1+1, 1+2, etc for the dilutions. That makes more sense to me.

    Exactly!!! Just recently I looked at developing time and solution, I questioned it. Thanks for the clarification from everyone.

    I understand from a fomer thread that some chmists use the colon to mean something else. Kodak manuals almost always use 1:1 to mean One part stock solution to one part of water. Ilford instructions use 1+1 to mean the same thing.

    I don't think I have seen the 1+0 notation on any packages but it would mean one part stock to zero parts water - In other words no dilution.

    if you find the Kodak instuctions for D76 confusing, the Ilford instructions for ID-11 may be clearer, the two products are used the same. Ilfords version is mixed from Powder somewhat differently as it is packaged in more than one envelope. But the stock is generally equivalent to Kodak D76 stock.

    The Kodak instructions for use and mixing are almost invariably in very clear words. They tend to be accompanied, however by tables that use the 1:1 notation.

    I believe one of the main differences between using D-76 straight and using it diluted, is due to the silver solvent it and many other developers contain. When used diluted, the silver solvent is not as active relative to development time, thus negatives might be slightly grainer (more sharply defined grain), but also slightly sharper over-all.
    At least with LF landscape, a bad day of photography can still be a good day of exercise.

    Yes, softening/smoothing is the primary thing you can control via dilution on D76.
