I know you are pulling my chain, if only just a little, but.... not a
bad idea to try out. One of the difficulties I have in converting color
to B&W is deciding on the tonal balance. Somebody posted a while ago
that some photo editors convert using just the green channel. In looking
at these, I did a little testing. I can now say that PS does not do
that. I looked at a couple of my images using the PS Unsaturate command
and each of the three color channels individually, just to get some idea
of what I was dealing with
<http://www.moosemystic.net/Gallery/tech/B&Wconv.htm>.
In both of these, the blue channel did not fill the histogram highlight
end. Using levels to fill the highlights lightened it a bit, but I left
the above samples just as they came.
One of the interesting things about this whole series is the effect of
the direction of the light and the direction from which I took the pics.
SC16 and SC19 were taken with the light roughly behind me. SC20 and SC21
are of the same wall area as SC16. but with the light roughly in front
of me. The result in the visible texture of the painted concrete is
quite different, and I emphasized this difference in post.
Next, I converted four of the images to B&W and have added them to the
gallery as mouse roll-over alternates to the color images
<cid:part1.07090606.02060801@gmail.com>.
The conversion of SC16 doesn't do a thing for me, the subtle variations
in the ocher color just become uninteresting blotchiness to me.
Likewise, SC17 doesn't do much for me. It's better than SC16, but part
of what I like so much about SC17 is the two geometric patches of
simple color at the edges of the monochromatic main body. Not as strong
for me in B&W.
SC19 and SC21 are a different story. In SC19, the relatively amorphous
wall, which derives its interest from the color, derives a different
interest that I like from the texture revealed in the blue channel, with
slight adjustment. SC21 goes way beyond that, with an unnaturalistic,
but pleasing to me, unmasking of the cornucopia of texture from the
uneven application of paint and, presumably, it's reaction with the
concrete. Sort of an x-ray of the thin, but complex layer of paint.
Thanks for the suggestion, that was fun and informative!
