Steve, thanks for the link to a most interesting article. I've known for a great many years that I'm partially blue/green colour blind, or in other words as the article suggests I see the blue/green colour divide differently to others. In point of fact I see it the same as my father saw it but differently to how my mother saw it. I was told at the time I was tested (1979) that some 10% of the male population react in this manner but only 1% of the female population, so mother was probably right, assuming there is a right. I wonder if that has something to do with my liking more muted colour images particularly with respect to landscape and reacting badly to what might be called the "Velvia" type landscape with very saturated blues and greens, some of which I find quite distasteful.
Having been processing some of my old 35mm and 120 film negatives over the past few weeks I was also interested to see the thoughts on film v digital, I've certainly been appreciating film output better and am swinging to the idea that it produces a more satisfying image compared to a digital one. I've expressed this idea in a recent post but was totally unable to explain why I had those feelings, most interesting.
