Consider the main types of polarization filter. Why do we need a "polar"? The light processing in the camera is changed using a polarizing filter. He perfects the frame, removing light "bloopers."
Using a polarizing filter changes the color depth of the images.
1) Water shot. Using a polarizing filter when shooting water, you can correct glare and color of water. Water is obtained in a very pleasant color, characterized by rich blue. Without the use of a filter, the water will turn out not so beautiful.
2) Sky shot. When shooting the sky with a polarizing filter, it is advisable to do this when the sun is located at an angle of 90 degrees. Thus, you will achieve the optimal effect. The color depends on the sun, so it is not recommended to shoot when the celestial body is behind the camera (the result is much worse), and also against the sun - the filter effect is almost not felt. A polarizing filter will help to remove atmospheric gaps that occur in natural light.
3) Color. The main plus is that when shooting with a polarizing filter there will be no reflections on objects. An example of this is the improved quality of leaves in the forest (pictured).
4) Reflections and glare from other surfaces. Using a polarizing filter, it can be perfectly removed through the glass. Without it, this is not an easy task. Also this product will help you to shoot any shiny objects better.
5) Lens protection. The filter, in fact, is an additional layer that protects an expensive lens, however, for these purposes it is better to use UV filters, which are much cheaper and do not affect the light flux.
How to choose a polarizing filter?
For cameras with mirrors with autofocus, a circular polarizing filter is required, with which it will be possible, by rotating the external element of the filter, to change the level of exposure to light on the resulting image.
In the markets you can find different types of polarizing filters, both from domestic and foreign manufacturers. They are all different in price and quality, so a lot depends on your financial situation and product requirements.
If you decide to purchase "polarizers" at a high price, then, of course, they will effectively improve the color of images and eliminate light flaws. Expensive polarizing filters are more resistant to scratches and mechanical damage, which justifies their cost.
If the budget is limited, then when choosing a filter it is best to focus on the manufacturer, since the quality of the resulting images is more important than design and usability. And for the safety of the filter, you can purchase a special cover and a storage container that will protect it from unwanted damage.
Thus, the choice of a polarization filter is not an easy task, but it can be solved, especially when the scope of its application and the quality requirements for the resulting images are known.
