Using this filter, reflections and glare can be reduced significantly from non-metallic surfaces. It will also help to greatly reduce the softness caused by atmospheric haze.

Polarizing filters achieve their greatest effect of eliminating glare when used at a 30-40 degree angle to a reflective surface, such as glass or water. At midday, when the sun is directly overhead or at a 90 degree angle, the filter will have the least effect. These effects are easily visible by rotating the filter and looking through the viewfinder of the camera. Keep in mind that you will first need to adjust the polarizing filter before setting the exposure controls.

To deepen the color of the blue sky and make the clouds stand out, hold the camera at a right angle to the sun and take the photo when the sun is at a 30-40 degree angle in the sky.

When photographing distant subjects, scenery sometimes appears bluish, which is also caused by light polarization. Using the polarizing filter will help to greatly reduce the softness caused by atmospheric haze.

There are a variety of ways in which the use of polarizing filters can help you capture that perfect shot. Reducing haze and enhancing colors may seem like simple effects, but once used, these effects will prove to be invaluable to photographers at any level of interest.
