    I agree with Bob - this treatment produces a nice sense of depth in the print that I haven't been able to get otherwise.

    OK. I've got it figured. Nelson's is a hypo-alum
    toner minus the alum. So it's a hypo toner. The
    little silver added is typical of hypo-alum toners.
    As with hypo-alum toners it's inclusion is to
    retard the bleaching effect.

    The gold acts as a catalyst. Bath temperatures
    run 15 to 20 degrees below those of hypo-alum.
    So, no alum needed. The minute amount of gold
    present, directly and indirectly, alters the color.
    In essence Nelson's is a sulfide toner. As such
    there should be no doubt as to the archival
    quality of your prints.

    Your's is off-the-shelf or Home-Brew?
    No matter the amount of silver added at
    start or the amount leached into the solution,
    bleaching may need to be lived with. Have you
    tried it at room temperature? Although slow, one
    hour, it is reported to work. Dan

    Good point. I find that toning can have a huge impact, and it's often hard to predict exactly what will happen when toning at a later time.

    I went for an all alkaline process where I can go; developer, water stop, first fix (in my case TF-3), second fix (TF-3 again), and then straight into the selenium toner. A finished wet print in around 7 or 8 minutes. It's so convenient I even selenium tone test strips when I'm getting close to making big decisions.
