Completely OT but about polarization:
I can across an interesting reference on the web discussing the fact that
human eyes can detect light polarization. It is fairly well known bees use
light polarization for navigation but evidently the (in)famous Feynman
lectures on Physics refer to the fact that you can do a test on youself to
demonstrate polarization detection. It would be interesting to know if this
has some biological advantage or whether it is a chance effect. Since a
normal print (even from a Zuiko) does not maintain polarization in the
picture, is this something that subtly affects our perception of real life.
When you use a polarizer on distant mountains you often get very significant
color shifts from light reflected off the rocky surfaces so in a simple way
that is true but maybe we percieve more subtle differences from polarization?
