This NiSi 67mm Circular Long Exposure Filter Kit contains four filters that are compatible with lenses that feature 67mm front filter threads. They can be used individually or in various combinations to create 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. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters. The included filters consist of four solid neutral density filters that reduce the amount of light entering a lens by 3, 10, and 15 stops, as well as a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, the solid neutral density and circular polarizer filter provides a 6-stop exposure reduction while helping to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A filter pouch is included to store and transport this filter kit. It features four padded, nonabrasive pockets plus a touch-tab-fastened closure. NiSi 67mm HUC PRO Nano IRND 0.9 Filter (3-Stop) 0.9 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 3-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily Filter does not affect coloration of the image and is ideal for use with other filters Each surface includes one layer of NiSi HUC Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times HUC Nano coating provides enhanced protection to the filter's substrate and results in a more improved beading effect when in contact with water or oil for greater cleaning efficiency Constructed from optical glass for clarity Slim and durable aluminum alloy filter ring that minimizes the potential for vignetting while remaining lightweight Side knurling to provide a more textured grip when mounting or removing it from a lens 67mm front filter threads allow for use with other filters NiSi 67mm PRO Nano IRND 3.0 Filter (10-Stop) 3.0 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 10-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily Filter does not affect coloration of the image and is ideal for use with other filters Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times Nano coating provides an improved beading effect with water or oil for more efficient cleaning Constructed from optical glass for clarity Brass filter ring helps to prevent vignetting, jamming, and provides additional strength Side knurling to provide a more textured grip when mounting or removing it from a lens 67mm front filter threads allow for use with other filters NiSi 67mm PRO Nano IRND 4.5 Filter (15-Stop) 4.5 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 15-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily Filter does not affect coloration of the image and is ideal for use with other filters Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times Nano coating provides an improved beading effect with water or oil for more efficient cleaning Constructed from optical glass for clarity Brass filter ring helps to prevent vignetting, jamming, and provides additional strength Side knurling to provide a more textured grip when mounting or removing it from a lens 67mm front filter threads allow for use with other filters NiSi 67mm HUC PRO Nano IRND 1.8 and Polarizer Filter 1.8 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 64x filter factor with a 6-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily Polarizing filter effect arranges and filters directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface Clears up haze in distant landscapes and provides more saturated, vivid colors Strongest polarization effect when used at a 90° angle from the sun Circular polarizer effect is ideal for use with digital cameras and autofocus lenses, where a linear polarizer will often disrupt auto exposure and focus features Constructed from optical glass for clarity and color fidelity Slim and durable aluminum alloy filter ring that minimizes the potential for vignetting while remaining lightweight Filter ring can be rotated to adjust the intensity of the polarization effect 67mm front filter threads allow for use with other filters NiSi Filter Pouch for up to Four 95mm or 100 x 100mm Filters Designed to accommodate up to four 95mm or 100 x 100mm filters Soft, nonabrasive interior lining When photographing with a tripod, rear touch-tab loop allows placement around a tripod leg, putting filters in more immediate reach Touch-tab-fastened closure Durable canvas construction
