Technical data
1.Gorilla®* Glas
Thanks to its unique surface coating, the filter glass resists even the most adverse environmental conditions such as scratches and shocks or constant contact with the material. Distortion-free and highly light transmissive, this special glass is used for particularly high-quality photo products.
2.Luminance Coating
This special coating considerably increases the resistance of the optical surface to scratches and damage. At the same time, of course, the colour fidelity and light transmission of the various filter models are retained to their full extent.

Modus operandi
GND filter is the abbreviation for “graduated neutral density filter”, also called grey graduated filter.
A grey graduated filter is employed to balance the difference in brightness of the horizon. Generally, a soft GND filter is used to take shots whenever the sky is much brighter than the land or vice versa, when the city is much brighter than the sky.
This filter then has the same effect at the top edge as a grey filter; this effect attenuates uniformly towards the bottom.
