Circular Polarizer &
Wide Angle Lenses
Prepared 2008-08-16 by Bill Claff
I disagree with the advice that Circular Polarizing (CP)
filters should not be used at wide angles.
My feeling is that with a Through The Lens (TTL) system and the photographer should simply decide whether any filter, CP or otherwise, suits their needs.
This shot shows some darkening in the upper left corner.
But I like it very much and the color of the water would not have been so good without a CP.
