SW150 150x170mm Reverse-Graduated ND 0.9 Filter (3 Stops)

About this product

The Lee Filters SW150 150x170mm Reverse-Graduated ND 0.9 Filter (3 Stops) is a precision-engineered photographic filter designed for landscape photographers. Its reverse-graduated neutral density design features higher opacity at the center, gradually fading toward the edges to balance exposure between bright skies and darker foregrounds during sunrise and sunset. With a 0.9 density equivalent to three stops of light reduction, it enables longer exposures or wider apertures in high-illumination conditions. The non-coated surface preserves natural color rendition, and its compatibility with lenses of 24mm or wider on full-frame DSLRs ensures optimal performance. Handcrafted in the UK, this filter delivers smooth transitions without visible lines, enhancing image quality in seascapes and golden-hour shots.
