I don't doubt your experience (or that of the numerous other people who are nostalgic for CCD sensors) but what is the science behind this? Doesn't a sensor just, in effect, count photons - does a CMOS sensor count green photons reflected from a lawn more than it counts other green photons or more than a CCD sensor counts them?

Don't know the science, maybe these newer sensors are simply more sensitive to light so "see" the hues of reflected light that my CCD camera ignored?

I do know most dSLR's shift certain colors. I recall DPreview normally shows a color checker vs what the camera records/displays and it's almost always different for certain colors on the checker, while other colors will be spot on. Some will get every color spot on but the red ir more orange etc. These types of color shifts can not be corrected moving the WB around without affecting other parts of the image.

On the reflected light being more sensitive, I'm not sure why I am seeing this. I'm fairly new to nikons but don't recall ever seeing these green hues when people are standing on grass or near trees with my olympus dSLR's.
