Formatt Hitech 100 x 150mm Grad Neutral Density ND 0.9 Resin Filter - Hard Edge


The4 x 6" (100 x 150mm) Graduated Neutral Density 0.9 FilterfromFormatt Hitechhas several uses and offers the possibility to achieve otherwise unachievable results. It enables the shooter to adjust exposure without affecting color balance. A Graduated ND filter appears gray and reduces the amount of light reaching either the sensor of a digital camera or the film plane of a traditional film camera. It is clear at the bottom with a gradual transition to darker gray at the top. Primarily, this filter is used to control exposure when shooting bright landscapes where your horizon linedisplays a great exposure difference between sky and foregroundand you need to balance them out for apleasing exposure.


A Graduated Neutral Density filter is also used to create some unusual special effects such as capturing the "blur" of the rippling water of a waterfall or the swirling effect of city traffic. Since it allows the use of slower shutter speeds in bright light, it becomes possible to create these special effects that would normally not be possible to capture without the filter. And, since it can also help to control your depth of field, it permits you to shoot at wider apertures. Ultimately, its value is in helping to prevent bright, overly washed out images shot in bright light. Soft/Hard designation indicates the degree of transition of the filter. Soft edge grads have a smooth transition from clear to ND. Hard edge grads have a more defined hard lined transition and should be used for longer lenses.



Absorbing Cell Technology

The secret to Formatt's consistency in filter design lies in its unique "Absorbing Cell Technology" (A.C.T.); this unique process allows color correct dyes to be applied to optically pure, wafer thin absorbing cells and offers a controllability that ensures the smoothest grad lines and consistent color across the whole filter surface



Hitch filters are manufactured to exacting standards and can be counted on to be consistent filter to filter which means you can change filters mid shot or from day-to-day and still maintain the same exposure



Hitech filters are made by Formatt, a company with three generations of professional filter-making experience produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology have resulted in a standard of optical excellence unmatched anywhere else
