    P-80(П-80) PQ Developer

    Hi,
    this is my favorite paper developer, and I find it amazing for its longevity and capacity.I've decided to share the recipe, hope this is the right place.

    The developer is well buffered and develops with a neutral tone:
    П-80
    water - 750ml
    sodium sulfite, anh 20gr
    Hydroquinone 3,5gr
    Sodium Carbonate, anh 20gr
    Phenidone 0,15gr
    Sodium Bicarbonate 2,6gr
    Potassium Bromide 1,6gr
    Add water to 1 liter
    I use a 1% solution of phenidone in methyl alcohol, and add 15ml of that, instead.

    I've had excellent results with this developer, and I hope someone else will, as well.
    Nikola

    In where I live we use metric and never heard of grain hence gr --> gram

    Understandable!

    Metric standard is g (hence mg, kg) so we tend to use g in this part of the world.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?
