Again, my ignorance is showing, but I don't at all get the retinex stuff. What I did read dealt primarily with color blindness and how colors are affected by sodium and blue light. I didn't read anything that formed a connection for me between looking at a blue sky and ending up with a red sky in print.

I'm also lost on the whole callibration deal. If scans of my prints look like the actual prints then it seems reasonable to me to assume that the negatives are scanning relatively true.

I know that when I view a "scale" from black to white on my monitor I can see the full range from white to black. And I repeat, my print scans match the prints. If you're saying that I'm not really seeing what I think I'm seeing, that the image and the scan do not really match then it's all moot. In which case I'm sorry to have wasted everyone's time.
