Formatt Hitech 4 x 4" Solid Color Cool Blue 1 Filter

The 4 x 4" Solid Color Cool Blue 1 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 Cool Blue 1 filter is similar to a standard blue filter but is more intense. This is the weakest 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.
