Hitech 100 mm Neutral Density Filters. Hitech Neutral Density Filters extend the control of exposure parameters and are used in both colour and black & white photography to reduce the intensity of visible light by a known factor.
They are extremely useful in pictorial photography when shooting maximum apertures in bright light.
Since ND filters uniformly reduce light of all wavelengths, there is no effect on the colour rendition. They may be used singly or in multiples. They are available in 4 densities. The total filter density will equal the sum of the individual filter densities.
Made from lens quality optical resin. A complete range of durable, consistent and fine toleranced filters ensure predictable and repeatable results.
