    Could somebody give a guideline how to simulate - at least mimic - the
    bromoil process with PS?

    If you've got CS and want a 'quick-fix' method try playing about with
    Image>Adjustments>Shadow/highlight.

    Make sure you've got a tick in the 'Show more options' box.

    or if you're feeling artistic ,,,,,

    You could mimic the process like this
    Desaturate your image (Image>Adjustments>Desaturate)
    You should now have a B&W background image.

    Using the Magic Wand tool set the tolerance to 25 and turn off contiguous
    Choose the darkest part of the image.
    Select with the wand and save as a new copy layer

    Reselect the background layer (IMPORTANT)
    Set the Magic Wand tolerance to 50
    Choose the SAME darkest part of the image
    Select with the Wand and save as a new copy layer.

    Repeat the last four steps increasing the Magic Wand tolerance by 25 each
    time all the way up to 250

    You will now have 10 layers and a background image.
    Turn off or delete the background image.

    You are left with 10 layers of decreasing depth - similar to the gelatine
    depth matrix used in a bromoil picture.
    Do not re-arrange the layers - you need the deepest contrast at the top.

    You can now manipulate each layer individually in the following way

    Reset the tolerance on the Magic Wand to 255 to make sure you select
    everything on a layer.
    Choose the layer you want to work on.
    Use the magic wand to select all visible pixels on that layer.
    The tools (e.g. the paintbrush) will now only be applied to the selection.
    When you paint (for example) the unselected areas will 'repel' the paint in
    the same way that the water saturated gelatine of a bromoil repels oil
    paint.

    You can of course alter any layer in whatever way you wish using the other
    tools and/or filters and of course you can have as many layers as you like
    by changing the Magic Wand tolerance levels in smaller or larger increments
    during stage 1.

    Thank you very much for giving me an idea with your detailed
    description! It appears to be a prudential transfer of the process to
    the digital world, I have to delve into that... Seems to be rather
    elaborate, but that is the real bromoil process as well.
