Nikon Filters

The price for Nikon filters is though of course healthy - you know what I mean when you go out shopping them, espcially for 77mm, such as the UV filter L37C. This might not be an issue for a pro, but for amateurs it might.

 

Nikon Standard 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.

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.

I strongly recommend them You'll be glad you use them too.
