    Interesting stuff. How do you go about getting a digital negative from a
    digital print?

  4. The digital print is the negative.

    What was done was:
    Open the image in PS
    Convert to mono
    Invert it (make it a negative)
    Print it

    Now you have two choices here. You can print on a clear film, as was
    done for this workshop. You can also print on paper and then oil the
    paper to make it transparent. I did this several years ago to print gum
    bichromates. Normal olive oil or cooking oil, rubbed in, wipe of excess
    and then let dry so you are not getting oil all over everything. Works a
    treat.

    Cheers,

    This is really impressive.
    I especially like the modern fractal image on the old style photographic
    paper.
    A real juxtaposition, and it works really well.
    A very interesting article. Thanks.

  6. thanks.
    I've done the same in the past with gum bichromates but I think I prefer
    the salt process.
    I also was doing fractal images on aluminium using Liquid Light paint on
    print emulsion and it worked well. One of our major photography
    institutions exhibited them in a history of photography show.

    Mix and match to get the effects you want.

    Cheers,

    Wayne

    First you scan it, then you use Adobe DNG converter :)
