A filter changes the quality of light entering the camera.
A Nikon filter is an accessory that can be attached to the front of a lens to change the qualities of the resulting image. These are most often used by professional photographers to achieve a certain creative effect or overcome some hardware flaws with the camera. Nikon produces several standard filters, but many more exist that produce distinct effects and can enhance your photographic ability.
Instructions
1. Gently press a filter to the camera lens and rotate it to attach it to the camera.
2. Use an ultraviolet filter to prevent UV light from reaching the camera sensor. While this will do little do enhance the image, most photographers use them as a layer of protection against accidental lens damage.
3. Use a polarizing filter to limit the angle of light wavelength entering the camera. This will enrich the colors of the photo and enhance contrast. Additionally, it will let you see through certain transparent objects, like water, without glare.
4. Use an ND filter to reduce the total amount of light entering the camera. An ND filter, which stands for neutral density, is useful for lowering the exposure on an image during a bright day without changing the camera's current speed or aperture settings.
5. Use a graduated filter to reduce an exposure at one area of a photo. These filters have an ND gradient that darkens one area while keeping the other normal. This is most often used to keep deep blue sky color without overly darkening the foreground.
6. Use colorized filters to change the hue of the image without photo software. The color of the adjustment depends on the filter's specified color.
7. Remove a filter by gently unscrewing it from the lens.
