You're right. I just didn't want to complicate the issue which is, after all, about sensitivity and whether or not we can artificial recreate a Filter (be it Colour, ND or Grad) in camera. I contend that it's within the scope of the Bayer Demosaicing (yes, it's spelled correctly) Algorithm. However, the two remaining questions are; is this possible within the constraints of the processing power on board and can it be done without introducing moire artifacts?
I have to confess ignorance on these two questions, maybe someone else ...?
The day you think you've found perfection is the day you stop looking, then someone else will find it and move in front of you.
