The 4 x 4" Solid Color Yellow 3 Filter from Hitech allows you to add color or enhance the contrast of your image. This filter is made to the highest technical standard that delivers a filter that can be used with confidence. Tolerances are manufactured to such a high degree that similar filters can be exchanged from day to day without any trace of difference in the color. Hitech filters are 1.5 mm thick and do not bend like traditional resin filters.
The Solid Yellow 3 filter is used for black & white contrast and is particularly useful for midday sun and deep shadow. It accentuates clouds, reduces haze and will reproduce distant vistas better. It is the strongest grade available for this filter.
The secret to Hitech'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.
This process is revolutionary compared with conventional filter dying techniques by eliminating the need to directly coat the glass surface itself; The repeatable performance gained through A.C.T. ensures that at any time you have to swap like filters for like filters mid shoot you can do so with confidence with no discernible differences in color or density.
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.
