Hi Roger,

> How did you do the conversion to B&W in Photoshop?

For these the routine in converting RGB to B&W is actually quite
simple as the RGB was fairly monochromatic to start with.
I am not sure how I did it exactly, but it's something like
check out each of the RGB channels individually, pick the
one I like (usually Blue) delete the other 2, convert to Gray
scale, convert back to RGB, do some minor tonal adjustment with
curves; while there in curves, tone the image (I like a warm tone, so
R+5,G-5,B-10, more or less).

I could have kept all 3 channels and go straight for an RGB to Gray
conversion, and back again, as it's likely than the blue (or green)
channel alone won't hold enough of details in the shadow.

Hope that answered your question.  If I wasn't clear, shoot
me a question on or off-list, as you please.

Thanks for your feedback.  I much appreciate it, as I am my worst editor.
