I've redone the image.

The repro is much nicer but Greg, you should never normalise your R, G & B data! Normalising is really only meant to be done for mono subs within each channel, not across channels. If you do it between the R,G, and B components you may normalise a part of the image that is supposed to have a colour differential - pretty certain for this subject. The effect will be to subdue or remove colour in parts of the image. You should combine the RG & B as is and subsequently adjust any colour imbalance.

Cheers, Marcus
