Re: [ATM] Betr.: Re: cutting a big piece of plate glass - Polarizer

Friends
I just observed our metal roof, a black Weber grill  (barby), and a Dell 
lcd monitor with a Canon 55mm circular polarizer (PL-C), it is designed 
to rotate. I did not have the opportunity to look at a nice north, blue 
sky, because we are cloudy again in Texas.  Results, the apparent color 
temperture changed with rotation, from warm to cool, I should have used 
a linear as well, but that is another experiment. Something does indeed 
happen with rotation of a circular polarizer,  I am more a fan of the 
linear and manual settings in photography.
Cheers
JR
