Three shot is excellent , I like the final colors very much but I have another fox running in my mind. If you can find a bayer filter made not from only 3 colors but 1000 colors , what would be the result. An Belgian firm started to manufacture such bayer filters for hyperspectral imaging.
If we calculate how much the resolution drops , in your calculation , it must be more. I am stlll dont know how to merge these colors in to single photograph with 1000 layers of information. When you reach such a detail , film recording is still faster IMHO.
And what about when you use a bayer filter for 6x6 camera and film. You can beat me with small format digital camera but what happens when you go large and 1000 colors also ?
