Right! I found out how to separate the channels in CS. But unfortunately
my filter seems to be unsuitable for the job. The blue channel is very
dark. The green is about half as dense as the blue. The red channel is
brightest of course, but looks nothing like the picture Ralf posted,
despite it's abundance of trees, bushes and grass. The foliage is dark,
exactly the opposite of what is expected. So its back to square one. I
need to find the correct filter -- 87C. Ralf has located some for me in
a German Dealer's list at about €22 or so. That's a bit expensive for a
square of gelatin. Glass ones don't cost a lot more from Hong Kong. I
shall not rush this I have plenty of other things to occupy my mind at
the moment.

Just out of curiosity, Ralf...
How many RAW converters can actually treat the colour channels
separately?
How many? Ask your favourite computer journalist or software dealer. :-)
I understand that the RAW converter of Lightroom is the same as in
Photoshop. It includes a "greyscale mixer" where you can control how
much information from the different colour channels will be used in the
resulting b/w picture.
Photoshop has a function called "split channels" or something like this
(my version has all menus in German) in the "Channels" window.
That's all I'm familiar with.
