Kris at Destiny-601 has missed the point I was trying to make. The output
of a CRT is not green light, it is broadband light, albeit with a green
bias, just as the Xenon is broadband light with a blue bias. It is not the
same as putting a filter on the camera lens, which will only allow through
light of that colour.
Both Xenons and CRT's contain the complete visible light spectrum, but
neither are linear. Provided the detectors have the inverse non-linearity,
then the overall system - from photons to electrons, via the film and the
optics - is neutral.
Thanks to Casablanca Finish (Sao Paulo) for support in 1998..
