NiSi 150mm System Professional Kit Second Generation II

This 150mm System Professional Kit Second Generation II from NiSi contains five filters that are compatible with filter holders that can accept 150mm wide, 2mm thick filters. They can be used individually or in various combinations to improve the results of your photography. Included are two neutral density filters that can be used to create a darkening of the entire image a medium-edge graduated neutral density filter, which prevents overexposure in specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image a hard-edge reverse-graduated neutral density filter that can be applied to darken bright skies, specifically during a sunrise or sunset, while also allowing for a normal, unaffected exposure in the other regions of the image and a filter to reduce the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources.

A filter brush is provided for cleaning and maintenance of the filters, as well as padded pouch for storage and transport.

NiSi 150 x 150mm Nano IRND 1.8 Filter (6-Stop)

• Darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
• Providing a 6-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

NiSi 150 x 150mm Nano IRND 3.0 Filter (10-Stop)

• 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

NiSi 150 x 170mm Nano Medium-Edge Graduated IRND 0.9 Filter (3-Stop)

• Darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected
• 8x filter factor provides up to a 3-stop reduction of light in selective areas
• Medium-edged line of transition between the dense and clear areas
• Useful for images that include elements like rooftops and mountains that protrude into the sky
• 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

NiSi 150 x 170mm Nano Hard-Edge Reverse-Graduated IRND 0.9 to 0.15 Filter (3 to 0.5-Stop)

• Effectively darkens bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image
• 3-stop band of density that tapers to a 0.5-stop density at the edge above it while directly above a clear area creates a neutral density pattern that matches the positioning of the sun when it is at or immediately above the horizon
• 3-stop band of density extends approximately 4mm in both vertical directions
• Density pattern corresponds to the brightness pattern of the sun when it appears at or is closer to the horizon as opposed to a higher angle, which creates an increase in brightness that is more prominent on both sides of the sun than above it
• Hard-edged line of transition between the 3-stop band of density and the clear area below it is useful for hard transitions between the sky and land
• 3-stop to 0.5-stop gradation is applicable to multiple regions of brightness within the sky
• Filter does not affect the overall coloration of the image
• 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

NiSi 150 x 150mm Natural-Night Filter

• Reduces the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources
• For cameras with daylight film installed or a digital camera system with its daylight white balance setting selected
• Absorbs the yellow light from sodium-vapor or mercury-vapor lamps, common light sources within urban areas
• Enhances the visibility of astronomical objects, and where they appear, artificial light sources are more clearly defined with less glare and improved contrast
• 1.5 to 2.8x filter factor reduces exposure by 0.6 to 1.5 stops
• Constructed from optical glass for clarity
• Each glass surface includes one layer of nano coating that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency
