The 0.6, 100 x 150mm Hard-Edge Reverse Graduated Nano IRND Filter from NiSi is compatible with filter holders that support 2mm-thick, 100 x 150mm rectangular filters, including the NiSi 100mm system. It can be used to darken bright skies, specifically during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.

This filter has a 0.6 band of density across its center region. After a hard-edged line of transition, it tapers to a clear area. This design allows the filter to match the sun's position when it is at or immediately above the horizon. The hard-edged line of transition is useful for hard transitions between the sky and land. The filter features a waterproof and low reflection nano coating and comes with a leatherette carry pouch.

Q: 1. Could you provide a more specific nm range for this, or is the spectrum available?

A: Unfortunately, ND filters like the Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) that cut UV and IR light do not specify a nanometer range. This is because they are meant for long exposures photos without a color shift and not for IR photography.

A: The NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (16.5-Stop) is safe for camera sensors when used carefully and following the instructions.
