Questions about circular polarizer
1) How much blue/reflection can a polarizer remove from a scenery?
I was using Kenko Circular Polarizer and it did not remove reflections from the water totally nor render the sky any darker blue, as shown in the following.
2) I noticed that the Kenko circular polarizer introduced vigenetting...is that normal or is it because the CPL sucks?
I use Nikon D70s with 18-70mm.
