hear, hear.

I agree with everything you wrote Tom and appreciate the reply.
I had the opportunity not long ago to test, for a commercial that
would air in b+w, shooting on various color stocks and shooting on
b+w stock.  Needless to say the b+w stock won, for the reasons you
mentioned.

Forgetting film for a moment, and just talking about an 'image', the
question still remains for me: why is it we must add contrast to an
image that is originally in color, when we pull out the color?  I'm
in search of a scientific explanation; I've known about the phenomenon
since the 1970s, when I first sat in the chair.

Your dissertation on luminance and chroma deserves a place on the wiki,
I'll wait for this thread to spin out and combine it with other possible
responses in the technical discussions section.
