Polarizing Filters These filters are used to reduce or eliminate reflections. They are ideal for photographing through glass or water as the glare from water tends to be white. Polarizing filters can also reduce the effects of haze and darken the blue sky image in black and white and color photography. There are various polarizing filters available to increase color saturation in a photo without altering the hues of image colors, but there are only two principal styles. One style fits over your camera lens, while the other is made to be used over the source of light. They don't affect color, that's why polarizing filters and screens are used in both black and white and color photography. There are two pieces to a polarizer. The front part rotates so you can change the angle of polarization. If you look at the blue sky through a polarizer and rotate it, the sky appears to get darker and then lighter. These filters range in price from about $15 to $800. They come in various sizes.

Kenko variable NDX filter
Kenko-Tokina has created an adjustable neutral density (ND) filter which may be be varied from ND2.5 through ND1000. The Kenko variable NDX filter has the ability to make the scene darker from 1.3 through 10 EV. The filter allows wide aperture openings while preserving an accurate exposure within your camera's shutter speed range, or when using an extremely long shutter time to emphasize movement. The company recommends its use for capturing video with shallow field depths. Its variable nature permits the filtration degree to be decreased for focusing, then intensified to the wanted amount, without the need to take the filter off the lens. The filters may vignette when employed on lenses with an angle exceeding 28mm equivalent, The filter thread sizes come in in 77mm and 82mm  New Article aug 2, 2011
