4x4" (100x100mm) Resin 3 Piece Standard Neutral Density Filter Kit
The Neutral density kit contains the 3 most widely used ND densities - 0.3 (1 stop), 0.6 (2 stops) and 0.9 (3 stops). Neutral Density (or ND) filters produce a grey neutral effect and are used to reduce light in photography, enabling more control over exposure and depth of field without affecting color or contrast. NDs are made in different densities according to the level of light reduction from 1/3 to as much as 10 stops of light. This 100mm filter kit is usable with Formatt-Hitech 100mm holder systems or any 100mm holder. The kit is also available in 67mm, 85mm, 150mm and 165mm sizes. Formatt-Hitech filters are made from the highest quality 1.5mm optical resin.
