The main effect of a polarizing filter is that it eliminates the reflection from non-metal surfaces. It will enhance the colors in your photographs, making them rich and deep in color. No other filter is able to do that. When taking pictures of trees, leaves, foliage, etc., the polarizing filter will help them to appear less shiny.

A polarizing filter is most effective with skies, color enhancement, water and reflective surfaces, and light absorption. By eliminating the reflection of light, the polarizer produces saturated and slightly darker skies. The filter tends to enhance colors by making shadow areas darker. By eliminating reflections, the filter tends to make water and various other reflective surfaces more transparent. A side effect of the polarizing filter is that it absorbs 1.5 stop of light, so in low lighted situations, some type of camera support will be needed to develop the most effective photos.

Polarizing filters typically come in two types- screw-in filters or fitting one into a square filter. Screw-in filters are the right way to go if you typically use one lens, or if all your lenses have the same filter thread. When buying a polarizer that fits into one of the square filter systems, the Cokin A or P ranges are ideal for the small diameter lenses. The Lee filter system is very adaptable so it will fit almost any lens, including large diameter angle lenses and medium format cameras.

There are lots of different kinds of polarizing filters for sale, so the process of purchasing one can be overwhelming if youve never bought one before. The kind you buy will depend on your camera and your lens type. You can get the kind that screw onto your lens or the kind that is made to fit a particular lens size. Keep in mind that if you have a cheaper lens on your camera you may have a hard time finding a polarizing filter thats a good fit.

When you look through your camera for the first time with the filter in place everything will probably seem too dark. This is normal. Your eyes will get used to the effect, just give it time. Dont move the filter around too quickly in an attempt to make things seem brighter. Its best to move it slowly so that your eyes can pick out the different contrasts in the colors. Youll love the effect the polarizing filter has, and it will make taking landscape photographs much more enjoyable for you.

The purpose of polarizing filters is to filter the light rays that enter your camera lens. This filtering eliminates undesired reflections, increases color saturation and enhances contrast. The result is a clearer, more detailed picture. A Hoya polarizing filter is often used to enhance the contrast between blue skies and white clouds, but the filters do not alter the actual color balance of a photograph.
Hoya polarizing filters are also used to prevent undesired reflections from non-metallic surfaces like water and glass.

Hoya produces two kinds of polarizing filters: linear and circular. Linear Polarizing and Circular Polarizing filters have the same effect. Choosing the correct one will depend upon your camera recommendations.

Hoya polarizing filters are made with a hardened 8-layer waterproof multi-coating that is both scratch and stain resistant. This coating allows an average light transmission rate of greater than 99% on average distance shots. This impressively reduces reflections that bounce off the surface of the glass and enable you to capture greater light in your photographs.

Serious photographers should always carry a Hoya polarizing filter in their camera case. Great for outdoor shots, these polarizing filters are made for most types of cameras, from the medium format to the digital type point-and-shoot. Single lens reflex cameras with Autofocus require the Hoya circular polarizing filter, which allows front-side rotation.

Whatever the light or reflection challenge, the professionals at Hoya have created polarizing filters that can eliminate the problem. Consider making one part of your camera gear.

There are two types of polarising filters used in photography: the linear polarising filter and the circular polarising filter. Both the circular polarising filter and the linear polarising filter have the same effect but the autofocus and metering mechanisms of some cameras do not work well with linear polarising filters. This has the result that most photographers prefer to use circular polarising filters in their cameras.

Circular polarising filters come equipped with small linear polarising filters on the front but instead of splitting the light beams during the polarisation process – which is what a pure linear filter does – circular polarising filters select one direction of light beam while rejecting the others. The circular polarising filter will then use a retarder, or quarter wave plate, to change the polarisation of the light beams traveling through it. The light beams polarisation as initially selected by the linear polarising filter is thus changed inside the camera by the quarter wave plate into circularly polarised light. It is thus this alteration of the lights selected polarisation into circular polarisation which gives the circular polarising filter its name.

Circular polarising filters should be used when photographs are being taken of objects with non-metallic surfaces, like water, as they greatly reduce the glare caused by these surfaces reflecting the available light.
