The NiSi 82mm Nano IR Neutral Density Filter ND1000 is specially
designed for landscape photographers. This filter is made from
high-quality optical glass with nano coating to prevent losing any
single bit of detail. Neutral density filters do not affect the
coloration of the image and the 3.0 density provides a 10 stop reduction
in light from entering the lens.
Attaching a neutral density (ND) filter to your lens uniformly
reduces the amount of light entering the lens. The ND filter is helpful
when the contrast between the highlights and shadows is too great to get
quality exposure. The ND Filter also can enable greater motion blurring
and image detail by allowing a large aperture and/or a slow shutter
speed to be used. A variant on the ND filter is the graduated ND,
in which there is a gradient that effects the reduction of light in a
graduated, neutral level from 100% to 0% across the length of the
filter. The Graduated ND is recommended for shooting landscapes and
seascapes because you can reduce the brightness of the sky (for better
contrast) but still maintain an affecting exposure of the land or water. By using neutral density filter the camera is vulnerable to infrared
light which will cast the unwanted red color to the photos when shooting
at small aperture. The added the infrared protection coating layer to
this filter which helps to eliminate the infrared light through the lens
to bring back the natural color.
