The 85 x 110mm Graduated 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 standards that deliver 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. A Color Graduated filter generates the effect in the top part of the image while leaving the bottom clear. Traditionally, it is used to enhance skylines but its use can be varied to create many dramatic and moody effects.
This filter is available in a hard or soft edge variety. Hard edges contain a solid line between transition areas while a soft edge gently blends from top to bottom. It should be noted that many additional effects can be created by using two graduated filters opposed to each other, i.e. one used upside down from the other.
The Graduated Cool Blue 1 filter gives a steelier blue effect than the standard Grad Blue filter. It is the first 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, which 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.
