Hi there, the second image certainly shows the difference better.
I'm no expert in this area, but in my limited experience it appears that with a bit of sharpening and saturation, the two images might look identical. I hope you don't mind, but I grabbed your second image and did a quick 10 minute test to remove some Gaussian blur and upping the saturation in Photoshop Elements and got this result. You should be able to do much better with the original data (if you want to of course ).
I don't mean this as a criticism of your new technique, just wondering if all the additional work to deconvolve the colours is worth it? Maybe there are other advantages that weren't immediately obvious to me.
I don't mind Andrew. I personally see two things with your reprocessing the lower half. One is that I think the image is being pushed a little too far and the contrasts now look over-processed and has less of a 'photo' look. I could also push the upper image harder, but I feel that is already at the limit of my personal tastes. Secondly, the bottom image has increased the saturation, but of fewer tonal values. I think part of the difference in these color conversations are likely due to people's monitor's and ability to see color. I use a Asus PA328Q monitor (recently replaced by the PA329Q) which has similar specs. The color gamut is very wide and highly accurate. I have noticed before that I can clearly see issues with other people's images (particularly with black or shadow levels) that others cannot see on their monitor without taking measurements. So even with the adjustments you made, the winner in my book is still very clearly the upper image.
To further illustrate, I have attached a hyper saturated version comparing the two images. Both are on the same combined image, so any adjustments are identical. Of course the image is garish now, but the variation in color is definitely more prevalent on the left hand image.
With regard to the extra work to deconvolve the colors, it is pretty minimal for my workflow. I am used to working on whole moon mosaics, so processing takes many hours to complete. Separate deconvolution of the three color channels and a few other various steps takes about 5 minutes at most, so some slight color improvement with that timeframe is easily acceptable to me.
Thanks for your thoughts.
