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.

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