Here's my next version Lee. As I said above, I misread your post and assumed you only had a synthetic luminance from your RGB data, so my previous attempt was based only on your RGB data. I used pretty much the same processing in this one. And of course one of the good things about PI is that you can save your work as a project, so when you reload the next day all the stuff you did before (images, history) is still there to be further processed. No lost work.
Differences were:
-- A deconvolution on your (real) luminance
--LRGBCombination with the real luminance rather than the synthetic one (which I still used as a mask)
--Some sharpening with AtrousWaveletTransform.
--Noise reduction withTVGDenoise
--Upped the saturation a bit with CurvesTransformation
--The odd Histogram tweak here and there.


All up this has been an interesting thread. I learned a couple of new tricks from PI Guru Rick's workflow above.
