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. The total filter density will equal the sum of the individual filter densities.
The Hitech filter system is manufactured by Formatt Filters to offer versatility and creative capabilities to stills photographers. Hitech filters are manufactured using the Queens Award winning CR39 dyed substrate. Formatt developed a method of colouring CR39 in its liquid state, thereby ensuring consistency and accuracy of colour.
