    I have been using staining developers since the 1950s. In my experience, the presence or absence of image stain should be verified with a tranmission densitometer. Visual examination can result in an incorrect stain assessment.

    I came across another tanning developer formula recently. This one is from Focal, and it is quite old. Since I'm still waiting for my darkroom to get built, I haven't tried it, but it may be interesting.

    Focal tanning developer

    Pyrocatechin 2 g
    Sodium sulfite (5 percent soln.) 5 ml
    Sodium hydroxide (5 percent soln.) 10 ml
    Water to make 1 l

    Develop 15 to 20 minutes

    The developing recommendation was no doubt for old style (1950s) films.
