    In a word, they cut down on the amount of light that passes thru them. This is helpful when you have too much light and you don't want to use a small F/stop or faster shutter speed to cut down on the amount of light that enters your camera.

    ND filters come in varying degrees of light reduction and are rated by how much light they block. A #9 for example cuts down three full F/stops of light. A #6 cuts down two stops, and so on.

    There are two kinds of ND filters. Full ND's and Grads. Full ND filters cover the entire piece of glass with an even amount of light reduction. You can buy fulls in round filters that will screw onto the front of your lens.

    Grads are graduated from no light reduction to full reduction. Grads come in square or rectangle shape and must be used with a matte box to hold them in front of the lens. These are useful in cutting down the brightness of the sky while not affecting the foreground.

    SR makes a filter that you spin like a cp, and cuts from 2-8 stops

    costs 350$ though

    for the beginners, above is an example of a graduated ND filter where only a portion of the filter will cut the light.
