If you wanted to do this kind of pictures should:
- having a spectral representation of the IR illuminating … which no analytical tools seems almost impossible to me
- having the sensor response curve IR, which seems very difficult to find (or impossible)
But for what purpose?
Because in any case, given the illuminant “IR”, colors will be very different from those percepted. Indeed, the sight of a man extends a maximum of 300 to 750 nm in the best case and the IR range from 650 to 2500nm (or significantly more)
So if I summarize, the proposal I make to extend the range of “tint” until 8, solves the problem. I made a comparison with the same pictures (CR2) using DPP and RT . I obtain - by choosing the same points for SpotWB - the same ratio between the channels R, G, B on different locations in the image.
