NiSi Cinema 4 x 5.65" Nano Soft-Edge Graduated IRND 1.2 Filter ( 4-Stop )

NiSi Cinema 4 x 5.65" Nano Soft-Edge Graduated IRND 1.2 Filter ( 4-Stop ) is a rectangular filter that helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. This horizontally oriented filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas.

The design of this filter has been optimized for use with digital sensors, and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light when compared to traditional film, NiSi's Optical Nano Coating has been applied to each of this filter's surfaces to eliminate color casts and ensure cleaner, truer blacks.

●4 x 5.65" graduated neutral density filter darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected.
●Soft-edged line of horizontally oriented transition between the dense and clear areas.
●Each surface includes 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.
●Scratch-, oil-, and water-resistant nano-coating creates a protective layer over the glass, making it ideal for use in harsh environments and easy to clean.
●Constructed from optical glass for clarity.
