- NiSi 67mm Solid Neutral Density 1.8 and Circular Polarizer Filter (6-Stop)
- Filter Case
The NiSi 67mm Solid Neutral Density 1.8 and Circular Polarizer Filter is a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 64x filter factor provides a 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
Simultaneously, this filter can help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
This filter is non-coated and is constructed from optical glass for clarity and features an aluminum alloy filter ring that can be rotated to adjust the intensity of the polarization effect.
