Nisi 100x150mm Explorer Nano IR Reverse Graduated ND 0.9 camera filter

Explorer Nano IR Reverse GND 0.9

This 100x150mm rectangular filter darkens bright skies while leaving the foreground unaffected. The reverse graduated design places the darkest density at the transition line, ideal for sunrise or sunset scenes where light is strongest at the horizon. It provides a 3-stop reduction with a 0.9 density rating for balanced exposure control. The filter suits landscape photographers who shoot directly into the light source.

Check 100mm holder compatibility

Verify your filter holder accepts 100mm wide rectangular filters before ordering. This reverse GND works best where the horizon creates a sudden, hard boundary between land and sky. Gradual transitions such as mountains or treelines may not align with the fixed transition line. Ensure the 150mm length covers your lens field of view without vignetting when positioned in the holder.

Double-strength B270 glass with nano coating

A specialised hardening process makes the B270 glass twice as resistant to breakage as typical filter glass, suiting active outdoor use. IR layers maintain accurate colour rendition by blocking infrared contamination. Low-reflection nano coating reduces flare and ghosting while repelling water and oil for easier cleaning. The rectangular format slides into standard 100mm holder systems for secure mounting.
