Hi Stephen,
Thanks for your response. I am enjoying this dialogue and learning a lot
from it. You are bold to champion your C*n*n here as I suspect most are
like me and hope for a great success from Olympus. But your
contribution keeps things honest. More below:

Right, neutral. Under what color light? ;-)

I am not a disciple of Dan Margoulis and the "color by numbers"
approach, but occasionally I run into a tough image to correct where it
helps to open the Info and Curves dialogues in PS and use the white,
gray, and/or black droppers to pull the color palette into some
semblance of order. Finding a gray that really wants to be neutral is
often very tough however. For me this kind of correction is always
empiric. If it works, great! because it worked. But if it doesn't
work, you run from it. I am surprised that you are able to make of
workflow of this. Do you have tools to work with that I may not be
familiar with?
