If you said, “blue skies” then you’re certainly among the majority of photographers. However, that answer merely skims the surface of what a polarizer is really capable of. The primary purpose of a polarizing filter is to remove reflections. Here’s the thing. In short, you really need to know how to use this tool!
In the embedded video above, we’ll look at why you need one, when to use it, and how to use it under a variety of scenarios. Wagner Falls (38mm, FX) For this image, a polarizer was essential for showing detail under the water.

Aperture is measured in "f" numbers - a ratio of the diameter of the hole and the focal length of the lens. The size of this hole can be adjusted – a larger hole allows more light in, a smaller hole less. An important effect of this is the depth of field. Return to top.

To this extent they can be an important tool in helping photographers realize their creative vision; to put on film what they see in their minds' eye. At times the use of filters are almost mandated by the limitations of the medium. For example, film users quickly learn that, despite being called "panchromatic", film is extra sensitive to (i.e., overexposes) the blue and ultraviolet (UV) light in skies resulting in the dreaded "white sky" effect.
A filter may be needed to compensate for this bias. Another problem in using the grey scale pallet is that, with exception of the blue bias mentioned above, objects of similar reflectance may have similar tone values in the resulting print. With the exception of color correction filters, color filters are pretty much exclusively used by B&W photographers However, we share some other filters with color photographers.
