X4 GND

Introducing the World's Sharpest GND. 100% Guaranteed. We took our industry leading X4 ND filter and applied the same proven technology to the graduated neutral density filter, manufactured it with tempered SCHOTT B270® optical glass made in Germany, and the result is the X4 GND – the world’s sharpest and most color neutral GND, guaranteed.   GND is short for Graduated Neutral Density filter, which is a rectangular filter which increases the dynamic range of your camera. Shooting a sunset with a GND filter transforms a photograph from having blown out highlights to one with incredible dynamic range, and it does this in-camera, without the need for Photoshop, stacking multiple frames or HDR.
