A polarizing filter is used to eliminate or reduce reflections that can spoil your photos. These filters are ideal for taking shots through water and/or glass, as the glare from water generally tends to be white in color.
Polarizing filters can also help to reduce the effects of haze as well as darken the blue sky image in both color and black and white photography. They’re quite popular for landscape photography.
There are several polarizing filters available that are designed to increase color saturation in an image without altering the hues of the image colors, but there are only two principal styles of these filters.
One of them is designed to fit over the camera lens, and the other style is made to be used over the source of light.
The filters don’t affect color and that’s why polarizing filters and screens are used in both color and black and white photography. There are two sections to a polarizer.
The front of it rotates, which allows you to change the angle of polarization. If you view the blue sky through a polarizing filter and then rotate it, you’ll notice that the sky will appear to turn darker and then lighter.
Polarizing filters generally range in price from about $15 to $800 and are available in a variety of sizes.
