As a child, I used to theorize that maybe people have different tastes in everything because they perceived the same sensory data in radically different ways: What if you see blue as the colour that I call red? Not colour blindness, but every colour is simply switched on its way to the brain. Like my two cameras interpret the same scene taken at the same time. Yes, I still haven't managed to convince the Nikon that it is not in hell. But then, I'm not exactly convinced of it, either.
