Define Neutral Density

Define Neutral Density

The purpose of a neutral density filter, as used in photography, is to reduce the amount of light that passes through the lens, according to Michigan Technical University. According to the Web site tpub.com, the light intensity is reduced without affecting the color of the light. Reductions to the amount of light passing through the lens allow the use of a larger aperture or a slower shutter speed. This is often used in landscape photography and in bright light situations. The filters are usually referred to as ND filters by photographers.

Filter Appearance

    Neutral density filters are gray in color, according to tpub.com. The filters attach to the front of the lens either by the threaded filter attachment at the front of the lens or some other proprietary method developed by the filter manufacturer. The filters can be used in both color and black and white photography.

Density

    Neutral density filters come in a number of densities that reduce the amount of light passing through the lens by between one and six stops. Unfortunately, filter manufacturers use different identifications systems for labeling their filters. Follow manufacturer's instructions for determining the effect neutral density filters will have on the picture.

Uses

    One of the common uses of a neutral density filter is bright light situations. If the sunlight or light reflected off snow or water is too bright for a proper exposure, a ND filter will reduce the light reaching the film or sensor. Other uses include reducing the aperture to limit the depth of field and slowing shutter speeds to allow the blurring of motion.

Graduated Neutral Density

    Neutral density filters are uniform throughout the filter. A graduated neutral density filter has more light reduction in parts of the filter than others. The filters come in a number of blends and allow some special effects, such as vignetting.

Disadvantages

    ND filters are useful in limited situations, according to the web site cambridgeincolour.com. The filters can reduce shutter speeds unnecessarily or require increases to the ISO that may result in more grain in the photograph. In addition some filters can produce a color shift in the picture.
