Haida Red Diamond Hard-Edge Graduated ND 150x170mm Filter 1.2 Density 4-Stops camera filter

Haida Red Diamond 150x170mm Filter

The Haida Red Diamond Hard-Edge Graduated ND filter measures 150x170mm and provides a 1.2 density reduction equal to four stops. It is built from optical glass with a Nanopro coating that resists scratches, water, oil and fingerprints while remaining easy to clean. The hardened glass construction offers high resistance to shocks and breakage. Rounded R5 corners improve handling when inserting the filter into a holder.

Landscape photographers with straight horizons

This filter suits photographers who need precise exposure balance across a sharp horizon line such as seascapes or flat terrain. The hard-edge transition delivers a clean separation between the darkened and clear zones. Shooters working with uneven horizons, mountain ridges or tree lines will find the abrupt transition creates an unnatural line and should choose a soft-edge or reverse graduated filter instead. The 150mm width requires a compatible filter holder system.

Four-stop density for bright skies

The 1.2 density reduces light by four stops across the graduated portion, comfortably handling bright sky conditions while preserving foreground exposure. It works well for sunrise and sunset scenes where the horizon is the brightest element. Extremely high-contrast situations such as midday sun over water may exceed the four-stop range, requiring a higher density filter or exposure bracketing to capture the full dynamic range.
