Moose,
I went back to the RAW file and tried my best, within the limits of PS
Elements 6.0, to remove the clipping. I succeeded with the red, but the
blue is still clipped somewhat. However, I don't that is really noticeable.
I replaced the original image with the newly reworked image, same link.

I think this is a more natural rendition of the real scene. Even my wife
agrees!
