    D76H is something Grant Haist is purported to have hypothesised in a discussion with Bill Troop (see the FDC).

    Unfortunately Bill Troop gave iD76H a Kodak nomenclature something like H76 ie Haist 76 would have been better.

    Ian,

    I see that you made the same point a couple of pages back in this thread over the weekend when I wasn't checking APUG. In the interest of completeness, could you post the formula for D-76h (not Haist) here, as few people seem to be aware of it? I've not seen it published anywhere. I have seen a buffered D-76d formula with boric acid.

    D76h

    D76h

    Metol 2.5g
    Sodium Sulphite 100g
    Hydroquinone 5g
    Borax 2g
    Boric Acid 15g
    Water to 1litre

    This is very similar to a 1934 Kodak Research labs version published in the US & UK, but has the Metol increased to 2.5g
