Damn, well you're info on the TV broadcast versions now has pretty much killed my interest. I was looking at other photos from Tunsia locations just before the sun sets and combining that with what you pointed to about the different limitations of different capture methods, filtering etc. and when I look at a sunset like the following which contains so many different colours and brings out so many colours I don't see how the matter of the binary sunset can ever be settled definitely,
(more blue, more purple, more yellow, more sandy, more light, are too vague here + how is an early tv/vhs/laserdisc going to capture this complexity)
