The 4 x 5" Reverse Neutral Density Graduated 0.3 Filter from Hitech is the way to go when you want to shoot a bright horizon line but want to maintain accurate color balance between the horizon and foreground. Traditional graduated neutral density filters transition from dark to light towards the bottom of the filter. However, by providing a reverse effect, the Hitech Reverse Grad allows you to capture the brilliance of the sunrise or sunset while maintaining a controlled and pleasing exposure in your foreground. The filter is clear in the lower half but, as mentioned, graduates from dark to light towards the top. This holds your foreground while "toning down" the horizon line and upper half of the image.
For the nature or landscape shooter, this is an ideal filter that can save what might ordinarily be an impossible shot to capture on film or digital. On traditional film, it can compensate for the limited film latitude you may be dealing with (the number of stops that can be accurately recorded).
Hitech filters are made from high-quality CR39 resin. 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.
This filter is only available in a soft edge style. The transition will be gradual, subtle and even from horizon to the top of the filter.
