Got
this in an email from a mate. I'm not sure if this has been posted before but I found it fascinating. It also raises a few questions about how we perceive colors (amongst other things) while processing our pictures. Even when you are aware of it your eyes still see different colors. The brain is such a fantastic, adaptive and mysterious thing. Mind blowing realtime processing power. But it seems it
caches a lot of the information and that's where some of the
problem lies. Longish viewing but well worth the time IMHO. Enjoy.
