The NiSi Nano Vertical Soft-Edge Graduated IRND Filter 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. The 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. Neutral density filters do not affect the coloration of the image.
The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks when using the NiSi Nano Soft-Edge Graduated IRND Filter, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces.
This NiSi Nano Vertical Soft-Edge Graduated IRND Filter is constructed from optical glass for clarity as well as color fidelity,
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 transition between the dense and clear areas
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
Constructed from optical glass for clarity
Easy to clean
