Product Description

Neutral Density Filter

A Neutral-Density Filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition. It can be a colorless (clear) or grey filter. The purpose of a standard photographic neutral-density filter is to reduce the amount of light entering the lens.

An ND filter acts like sunglasses would to your eyes, it blocks light coming into the lens like sunglasses blocks light coming into your eyes. ND stands for Neutral Density which means it blocks the light in a neutral way without changing the colour of the light.

ND filters

ND filters are mainly used to darken down skies and balance out your exposure.
Below is an example using a hard grad ND filter. The one on the left is a normal picture shot using the camera's built in light meter. This is what the camera thought was the correct exposure. The one on the right with the 2 stop hard grad ND filter. This has darkened the sky by 2 stops to give a much more balanced exposure.

Neutral Density Filter Features:

 This Neutral Density filter or ND filter is a "grey" filter. It appears grey and reduces the amount of light reaching the film or sensor, but do not have an effect on color balance. The purpose of standard photograpic neutral filters is to allow the photographer greater flexibility to change the aperture or exposure time, allowing for more control, particularly in extreme circumstance, such as on a bright day.
