BD> Hi, Karen! (We gotta stop meetin' like this!)
KW> Why? :)
Jealous husbands, and all thet jazz? Hehheheheh
BD> I spent a decade doing news photography, too..
KW> That was never actually my job, but I've had a chance to do

KW> would be one job that would coax me back into the work force.
I felt much that way once but now when I wake up after dreaming
some situation had forced me back into news work, I give a huge
sigh of relief!! Just another nightmare! For me, this is one
of the situations that really fits the old saw: "I wouldn't take
a million for the experience, and I wouldn't do it again for two
million.
BD> As you know, filters pass light of their own color and retard

KW> Yes, of course. But the only experience I've had with [it was]

You might wish to memorize the color relationships, then, if you
have not already done so. Then if a need arises you would know
what filter color to use in order to get a desired separation if
you were confronted with adjoining, similar intensity, colors in
making a B&W copy. While it is basic to color, the practical
value in B&W applications is equally appropriate. I made up my
own, years ago, when my burning avocation was a love of sports
cars. It went this way: General Motors Builds Yucky Race Cars.
The essensce is the first letters standing for primary colors and
paired with their counterparts, as Green/Magenta, Blue/Yellow and
Red/Cyan. Think of them as opposites. If you want red to be a
lighter shade of grey, use a light red filter and everything red
in the scene will be more dense on the pan negative, thus lighter
in a print.. If red needs to be darker then a cyan filter would
do the job because it makes red areas weaker in the negative, etc.
Everyone recognizes the primaries, RGB, but some may not be very
comfortable with the secondaries. In case you forgot, each one is
comprised of approximately equal quantities of two primary colors;
Magenta is half red, half blue, Yellow is red and green (though it
never seemed possible in my head!), and; cyan is a mixture of blue
and green. Photographic color processes are all based upon that
premise, in one way or another.
