Great
value for the price and good construction. I have used Heliopan and Hoya polarizers and see no difference. Keep in mind that when used with wide-angle lenses of less than 21mm (62mm filter) you will get dark corners but this can happen with even the more expensive "slim" filters."

Protection Filters -
Ultraviolet Filters
Your camera won't allow you
to develop clear, crisp photos if your camera lens is
damaged or dirty. You can protect your thousand dollar lens
with a $20 filter if you use a UV or haze filter. These thin
glass filters are designed to screw onto the end of your
camera lens and you can just leave them on to protect your
lens. UV filters can help protect your lenses from dust,
moisture and scratches. If your lens is damaged it could
cost you quite a bit to repair or replace it. The filters
can also give you added benefits of correction for
Ultraviolet light which can show on your film as a bluish
cast and can sometimes distort distant details. UV filters
let you correct for the UV effect to varying degrees. They
are also useful if you are shooting mountain and marine
scenes, as the haze could affect the color and clarity of
the photos. UV filters can be bought for about $20.
Haze Filters Haze Filters
do just what they sound like, they filter out haze which is
created by minute particles of vapor and dust. Haze settles
in the atmosphere and can affect distant photographic
scenes. Haze forms when sunlight is scattered by minute
particles of matter that exist in the air. Atmospheric
conditions have an effect on the amount of haze in the air.
Mist, fog, smog, smoke and clouds are all different than
haze. Green and red light are scattered by haze, but not as
much as ultraviolet radiation, violet and blue light. If you
use filters to absorb scattered sunlight you can penetrate
the haze. Any filter that can absorb scattered sunlight can
be considered a haze filter.

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. |

Quantaray Circular Polarizer
Filter
Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens.
· They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
· They also saturate colors and increase contrast.
Creates dramatic sky/cloud contrast.
Saturates colors without changing color balance.
Mount rotates to control amount of effect.
Increases contrast equally well with black & white film. Check availability,

Neutral Density Filters
These filters are designed to reduce the amount of light coming through your camera lens without changing the color. Neutral density filters can reduce the assorted colors of light in the spectrum. White and colored light is transmitted through these filters and only the intensity of the light is affected. These filters are used with black and white and color film. If you have set your camera to its fastest shutter speed along with the smallest f/stop, but still can't take the photo without overexposing the film, you can use one of these filters to reduce the exposure further. The filters help to eliminate bright, washed out sections of a photo. Neutral density filters usually range in price from about $10 to $350. They are available in various sizes.

Special Effects Filters
There are many types of filters available that are designed to give your photographs special effects. These include filters for special color effects, star effects, spectral effects, soft effects, mist effects, multi image and multi exposure effects, graduated color, dual color and tricolor effects along with spot filters, center filters and other special effects filters. These filters are mainly made out of glass and enable you to experiment with your photos or give them specific effects. The filters are available in various colors, sizes, styles and densities. If you buy extra filters you definitely require a good camera bag with padding to hold and protect them. They generally range in price from about $20 to several hundred and many of these filters are sold individually or in sets. |

Camera filters are transparent or translucent optical elements that alter the properties of light entering the camera lens for the purpose of improving the image being recorded. Filters can affect contrast, sharpness, highlight flare, color, and light intensity, either individually, or in various combinations. They can also create a variety of "special effects." It is important to recognize that, even though there are many possibly confusing variations and applications, all filters behave a reasonably predictable way when their properties are understood and experienced. Most of these properties related similarly to filter use in both film and video imaging. The following will explain the basic optical characteristics of certain types of camera filters, as well as their applications. It is a foundation upon which to build by experience. Textual data cannot fully inform. There is always something new out there.
In their most successful applications, filter effects blend in with the rest of the image to help get the message across. Use caution when using a filter in a way that draws attention to itself as an effect. Combined with all the other elements of image-making, filters make visual statements, manipulate emotions and thought, and make believable what otherwise would not be. They get the viewer involved.
Filter Planning
Filter effects can become a key part of the "look" of a production, if considered in the planning stages. They can also provide a crucial last-minute fix to unexpected problems, if you have them readily available. Where possible, it is best to run advance tests for pre-conceived situations when time allows.
Filter Factors
Many filter types absorb light that must be compensated for when calculating exposure. These are supplied with either a recommended "filter factor" or a "stop value." Filter factors are multiples of the unfiltered exposure. Stop values are added to the stop to be set without the filter. Multiple filters will add stop values. Since each stop added is a doubling of the exposure, a filter factor of 2 is equal to a one stop increase. Example: three filters of one stop each will need three additional stops, or a filter factor of 2x2x2= 8 times the unfiltered exposure.
When in doubt in the field about compensation needed for a filter that you have no information on, you might use your light meter with the incident bulb removed. If you have a flat diffuser, use it, otherwise just leave the sensor bare. Aim it at an unchanging light source of sufficient intensity. On the ground, face up at a blank sky can be a good field situation. Make a reading without the filter. Watch out for your own shadow. Make a reading with the filter covering the entire sensor. No light should enter from the sides. The difference in the readings is the compensation needed for that filter. You could also use a spot meter, reading the same bright patch, with similar results. There are some exceptions to this depending on the filter color, the meter sensitivity, and the target color, but this is often better than taking a guess.
Filter Grades
Many filter types are available in a range of "grades" of differing strengths. This allows the extent of the effect to be tailored to suit various situations. The grade numbering range can vary with the effect type, and generally, the higher the number, the stronger the effect. Unless otherwise stated, there is no mathematical relationship between the numbers and the strengths. A grade 4 is not twice the strength of a grade 2. A grade 1 plus a grade 4 doesn't add up to a grade 5.
