Hitech 100mm Neutral Density Filter – ND 3.0. Hitech Neutral Density Filters extend the control of exposure parameters inblack & 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 and optical glass flats. A complete range of durable, consistent and fine toleranced filters ensure predictable and repeatable results.

PLEASE NOTE – THIS FILTER IS NOT SUITABLE FOR COLOUR PHOTOGRAPHY.
By greatly extending exposure times the Big Stopper blurs anything that is moving in your image, for example clouds, waterfalls, rivers, and the sea.
The filter can also be used on cityscapes to blur people or on roads and motorways to blur traffic.
