ND filters. Neutral density (ND) filters reduce the amount of light

reaching the lens without affecting colour balance. These high-

quality ‘L’ class filters use a light-absorbing material which is

vacuum-deposited on the surface. Can be used with black-and-

white or colour film. The ND4L filter reduces the light to one-

fourth its original level (2 stops).
