The 4 x 4" Hard-Edge 1.2 graduated neutral density glass filter from Formatt-Hitech helps to specifically darken skies and other bright areas of the image. The filter is denser at the edge and fades to become transparent in the middle, with a sharp transition line between the density areas and transparent areas. By having only a neutral density portion 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 image colouration and the 1.2 density offers a 4-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.
