The Kase KW100 is a 100x150 millimeter graduated neutral density filter with a density of 1.2, designed for professional photography applications. This rectangular filter features a gradual transition from clear to neutral density, allowing photographers to balance exposure between bright skies and darker foregrounds without color cast. The 1.2 density provides approximately 4 stops of light reduction in the densest area, making it ideal for landscape, architectural, and outdoor photography where dynamic range management is essential.

Constructed with premium optical glass, the filter maintains color accuracy and sharpness while minimizing reflections and ghosting. The 100x150 millimeter dimensions ensure compatibility with standard filter holder systems from most major manufacturers. The neutral density coating is applied using advanced vacuum deposition technology for consistent density and durability.

This filter is particularly useful for sunrise and sunset photography, coastal scenes, and any situation with significant brightness variations within the frame. The gradual transition zone allows for natural-looking exposure blending without visible hard lines. The filter features hardened glass with scratch-resistant coatings and comes in a protective storage case to maintain optical quality during transport.

Kase filters are known for their precise manufacturing tolerances and consistent performance across production batches. The KW100 series is part of Kase's professional filter system, designed to work seamlessly with their magnetic filter holders and other accessories. This filter helps photographers achieve balanced exposures in challenging lighting conditions while preserving image quality and color fidelity.
