[Leica] Polarizing filter

[leicam4pro at yahoo.com (John Biava)]

I have used the swing out polarizers with various lenses on my M4.  I swing 
the filter in front of the viewfinder, asjust for effect, swing it back in 
front of the lens.  
   
  For exposure only one technique seems to work best.   Bracket   Meters are 
not universally reliable with filters.  CDs ( MR 4 ) do not always have the 
same spectral sensitivity as we expect, and can sometimes be sensitive to 
polarization as well.
   
  The effects of polarizing filters also vary with the angle of the sun in 
relation to the axis of the lens.  On one occasion a polarizer turned a 
clear blue sky unbelievable dark in a color shot.

Others on this List more regularly use polarizers 
than do I and really ought to speak up.
