The biggest use of a polarizer is to get that deep blue sky effect.

I rather would say no, because, to my limited knowledge, it is use to reduce the stray lights that exist from different reflection surface. the common use is to reduce the reflection on windows so you can have a  clear shot through the window.

It is a filter with two filters that allows only light coming in one direction. so if you rotate them to reach an angle of 90 degree, then it is suppose to have filter all stray lights. So, you have a few stops drop of aperture.

The richer color saturation is the result of less stray lights.

ND filter only lower the intensity of incident light instead of filtering the reflected light.

Also, not that it is a big deal, but in response to Sheep, how often do you need to reduce glare / reflections from windows or bodies of water?Lik 發表於 2011-5-13 10:01

    I am just saying that the filter is design for such purpose. You can do with whatever filter to achieve whatever effect you want. Photography is creativity.
