NiSi 100 x 150mm Explorer Reverse-Graduated IRND 0.9 Filter (3-Stop)

The NiSi 100 x 150mm Explorer Reverse-Graduated IRND 0.9 Filter (3-Stop) is compatible with filter holders capable of holding 100mm wide filters with a thickness of 2mm. Designed to darken specific areas of an image such as bright skies while still allowing normal unaffected exposure to the rest of the image.

A band of density can be found across the centre of the filter, this will reduce the amount of light entering the lens. Perfect for photographing sunrise of sunset. The band extends in both horizontal directions for about 4mm where density tapers gradually.

The NiSi 100 x 150mm Explorer Reverse-Graduated IRND 0.9 Filter (3-Stop) is made from tempered Schott B270 glass, which makes it shock resistant as well as increases clarity and colour fidelity. A layer of NiSi Optical Nano Coating is applied to all surfaces of the filter, with this coating applied it is easier to clean your filter and an improved beading effect will be seen when in contact with oil or water.
