How To Use The Polarizing Filter.

A camera with manual focus is simple: install the filter in its objective, begin to turn the filter controlling the result through the viewfinder. The effect is most noticeable in dark parts of the composition. Use the sign in the configuration of the filter more accurate. Sometimes you may find that the effect is minimal due to the location of the light source (usually the sun). If the light is formed by an area of less than 90 degrees on the side closest to the axis of the lens, the effect of polarization can not occur.

At the same time, if the sun is about 90 degrees on the side closest to the axis of the lens, the effect is maximum. To reduce glare on surfaces such as water, the goal has to be about 30-40 degrees from the surface.


You can also use polarizing filters with other types of filters. In doing so, the polarizing filter should be the last in its objective. This rule is not hard to remember, because in most cases do not have external threading. Try it! The combination of color filters and polarizers can give unusual effects, enlargement or reduction of some of the colors in the photo.

A final point to consider: the use of iodine filters can not withstand the heat and ultraviolet light. Therefore, applying the filter only when you really need it and keep it in a case in the rest of the time. Simple! Used correctly, a polarizing filter will last for about 5-6 years before it needs replacing.

Difference With Polarizing Filter.

The main objectives of the use of polarizing filters is to eliminate "soft" reflection, white-outs and reduce glare from non-metallic surfaces, in most cases and increase the color balance.


For example, it could become whitish blue sky, rich in the image that the filter has been used. This coupled with a great composition can totally change the viewers' impression. In summary, a polarizing filter is a "must have" accessory for every professional photographer and can be used for both white and black color photography.

To unlock the secret of this filter, you must use it properly.
Find the correct size filter for the lens being used. (55mm on a 55mm, etc.). Secondly, the filter thread on the front of the lens (closer to the subject.) After the filter is easily attached to the lens, rotate it.

Look through the viewfinder as you rotate the filter and see the results immediately. His landscape images have a new look, the sky is bluer, the clouds brighter and the grass green. If you stay at a 90 degree angle to the sun, you get the maximum effect.. Not with the sun in front of you or behind you to take the picture.

A polarizing filter, used correctly, on a cloudy day to saturate the colors of the leaves wet giving life to the image. Of course, great care must be taken in a day of poor light as a filter can make your image too dark. This filters will reduce the amount of light reaching your film or sensor. To counter the decline of light that reaches the sensor or film, open the aperture or slow shutter speed to compensate.

Best Buy For Polarizer Filters.

If you are only going to buy a filter for landscape photography is a polarizing filter to be used more. This filters can be used with color or black and white and is probably the most important one on the market today.


There are different types of polarizing filters. And this one is especially important because the software available today just does not come up to par with duplicating the results of using a polarizing filter at the time of exposure. When choosing a filter, decide if you need a linear or a circular polarizer.

Basically, if you are using an auto-focus single-lens-reflex camera, you would need the circular one. This is because of the beam splitting metering system that the digital camera uses.

Cheap Price For Polarizer Filters.

The only difference is the quality of the glass and construction. You want the best quality glass, glass of low quality because it will reduce the image quality. The glass will also do better, but not both.


It is almost impossible to make a perfect polarizer and circular polarizer aluminum foil perfect. It's expensive for the polarization of aluminum foil between two pieces of optical glass in a perfect shape. They are the shortcuts on the use of a piece of glass, not perfectly parallel use of glass, the glass is not glued to the polarization film, and the use of the foil polarization cheap.

Aluminum circular polarizing must do the following:

Eliminate the linear polarizing light of the "wrong" direction equally across the spectrum;

Linearly polarizing light passing from the direction equally across the spectrum, and

Circularly polarizing the linearly polarized light output of the linear polarizer completely in all wavelengths. This is the most difficult to achieve but is the least important.

All three are difficult to meet, and imperfections can lead to differences of color, but lighter than the issue can not in many circumstances.

Just try to stay away from anything that seems too good to be true.

Something of a polarizing, however, you really do not want to think about a cheap price, so go with something a little better.

Best Quality Polarizer Filters.

Let's take a look at the science behind it. A polarizing filter is composed of two pieces of glass cut to rotate all the reflections in metallic surfaces. Light travels in waves - the waves travel in all directions and at different prices and speeds. The polarizing filter, limiting the number of waves entering his goal. You decide the number of waves passing through the lens by rotating the filter.
The polarizing filter is most effective with side lighting.


For example, if you're taking a photo of a picturesque lake and is a cluttered clouds reflect in the lake will be too much of a distraction in the final image. This can be simply removed by rotating the polarizing filter until the clouds disappear. You can see the filter working in the viewfinder of his camera.

The polarizing filter will also darken the blue sky to give a rich color strong. Fog will be highlighted and can also be used to facilitate a rapid flow of water from fog effect.

You do not have to turn the filter of the total amount for maximum effect you need, sometimes you just have to turn a small amount. You can decide what best to see yourself through your viewfinder while rotating the polarizing filter.

This filter is not only a landscape photographer.

There are many different uses of a polarizing filter, which is so important to all photographers. The photographers are the property of this filter very useful - when taking a picture of a facade, the polarizing filter to remove the gloss, which is reflected in the glass.

Types Of Polarizing Filters.

Although armed with these good intentions, buy a polarizer filter can lead to confusion. There are a lot of different types, and may have up to 7, including: C - PL, MC - CPL, Big C - PL, Safe Water Shield PL-C, C DHG - PL. How do they differ?


The first filter, called PL is used to MF (manual focus), only the cameras and uses a linear polarization. The second type is for any MF / AF (Manual / Auto Focus) and utilizes a circular polarization camera. If using polarizing filters with an auto focus camera, make sure the filter of С. PL / PL-C logo on it, or is otherwise clearly a circular polarizing filter. We will discuss later why it is so important.

Some filters with larger diameters is only linear. MC filters - CPL and MC - PL brands use multilevel coating effectively minimize glare and reflections and providing more light. Water Proof Coat-CMP C-PL or PL, in its current form of the name, has a water resistant material on the external surface. The last C-PL DHG filter is specifically designed to protect digital camera lens.

Polarized light by a linear filter (PL) can cause errors in the opening and the approach of measuring auto focus on all digital cameras. With polarized glass was equal to 90 degrees, the digital camera is likely that it will stop processing the image at all. To avoid this, the use of circular polarizing filter (PL-C) that does not cause these effects. There are other important differences between these two types of filters, so you can select the most appropriate for their purpose.

Reviews Of Polarizer Filters.

Despite using a polarizing filter has many benefits that outweigh the disadvantages, there are several difficulties in using a polarizing filter. Most problems can be avoided with a little knowledge.

The first thing one needs to know about a polarizing filter is that there are 2 different types. One is the linear polarization filter and the other is the circular polarizer filter. A circular or a linear filter will do the same thing for your images, enhance them. For comparison, the circular filter is more expensive and the linear filter may not be the best option for most cameras that use auto focus.


A linear filter often ruin the performance of auto focus, the camera is not capable of transforming information from the filter correctly. A circular polarizing filter has added a layer that encodes the filtered light from the polarizer and the camera can read the information more clearly.

The extra layer in the circular filter is the main reason for the move is more expensive. But as you can see it is often worth the extra expense. Also, be sure to buy a filter that there is no color in the filter. Some filters come with an odd cast, green or yellow, make sure your filter has only a neutral gray cast.

Another problem identified with polarizing filters is to use wide angle lens (28 mm or larger). A wide-angle lens can see the edge of the filter, causing a darkening at the edges of the image. In addition, the sky may become unevenly polarized as the polarization varies with the angle of the sun and a wide-angle lens covers a wider area of the sky.

Even with some difficulties, the results obtained with a circular polarizing filter is definitely worth the price of the filter. Using a polarizing filter will take your images to a new level.
