I think you're trying to make a very simple process into something too
complicated. It's true you have to forget your negative photography
filtering but, once you do and are working with positive images you'll
find that the process is WYSWIG. In ACR (and I assume with Olympus
Viewer as well) you tell the software to convert to graytone (B&W). In
ACR your color image will disappear and be replaced by a graytone image.
The underlying color image is still there but hidden. What also
appears is a set of color sliders for modifying the luminance of the
underlying color channels. ACR will have already modified the sliders
somewhat to make what it considers a representative B&W image. Then the
sliders are left in place for you to twiddle to your heart's content.
Remembering that this is a WYSIWYG process, if you want to darken the
blue sky then move the blue slider to the left. If you want to brighten
the foliage move the green and/or yellow sliders to the right.
PhotoShop does allow inverting the colors of an image. I suppose that
means you'd be able to do the filtration using your conventional
negative filters as you suggest below. But after you've learned to do
WYSIWIG filtering I don't know why you'd want to use the negative
methods. Take advantage of the technology. It's fast and easy.

So, if I want to do detailed B&W photography I'm going to have to
stick with film. Or, learn an entirely different method. Is there
perhaps a way of taking a colour image, producing a negative which
can then be filtered, converted back to a positive image, and then
converted to a B&W image?
