The Formatt-Hitech 4 x 4" 0.6 hard graduated neutral density glass filter allows you to specifically darken skies and other bright areas of the image. The filter is denser at the edge and lightens towards the middle, with a sharp transition line between the density areas and clear areas. By having only a portion of neutral density on the filter, you can selectively darken areas of an image whilst allowing the part of the image in the clear section to receive normal exposure. Neutral density filters do not affect the colour of the image and the 0.6 density provides a 2-stop reduction of light entering the lens.

Formatt-Hitech glass filters are manufactured from high-quality Schott Superwite glass for exceptional clarity and maintained light transmission. This filter is compatible with the Formatt Hitech 100mm filter holder and measures 4 x 4" / 101.6 x 101.6mm.
