One of the many reasons people become attracted to photography is the capability of capturing the world around us in wondrous ways. While choosing large apertures or developing a dramatic style in post processing can completely change a setting, there are also subtle but supportive ways to change a scene. Such a way is through the use of a circular polarizing filter (CPF). In this well presented and thorough video tutorial, nature photographer Steve Perry of Backcountry Gallery will teach you everything there is to know about this must-have lens filter.
As Perry quickly clarifies for us in the video, polarizing filters do much more than just make blue skies bluer. Their ability to control reflections allows one to cut down on the amount of reflected light in a scene, thus giving more apparent saturated color. Unlike many other different types of lens filters, this is one that cannot be simply faked in post processing. Without recording the detail information hidden under a reflection, you are not going to be able to remove vivid reflections in post. In addition to this fact, Perry explains how a polarizing filter can be used in a variety of scenarios. At the end of the video he offers 4 random tips about polarizers as well as a buying guide to choosing the right filter.

With the turn of a CPF, the world changes it’s appearance before our eyes. For those of us who strive to represent the world in our own way, this filter is an essential piece to our gear bag.
