Breakthrough Photography 100x150mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter

Under the banner of world-class photographic equipment, we present the 100x150mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter, the pinnacle of our X4 ND filter technology. This filter, crafted from tempered SCHOTT B270 optical glass from Germany, stands as the world's sharpest and most color-neutral Graduated Neutral Density (GND) filter.

A GND filter is a rectangular tool that significantly enhances your camera's dynamic range. It is particularly effective when capturing sunrise or sunset images, transforming photographs with blown-out highlights into stunning shots with incredible dynamic range. This transformation happens in-camera, eliminating the need for post-processing techniques like Photoshop, stacking multiple frames, or HDR.

Outdoor photographers often grapple with dynamic range issues. While the human eye can perceive a dynamic range of over 20-stops, a mid-day outdoor scene may range between 15-18 stops. Professional camera systems typically offer a range between 12-14 stops. The X4 GND filter bridges this gap, expanding your camera's dynamic range to more closely match what the human eye can see.

The X4 GND filter works by decreasing highlight zones, akin to how the Zone System by Ansel Adams operates in the darkroom. While post-processing techniques like HDR can mimic expanded dynamic range, they often sacrifice the long exposure element that is crucial to capturing the best sunset scenes.

The X4 GND filter is a new generation of GND, building on the legacy of American-made Singh-Ray GND filters, known for their unparalleled color neutrality and high-quality CR-39 optical resin. The X4 GND filter takes this a step further, introducing SCHOTT B270 optical glass for superior durability and resolving power. This tempered glass GND filter is incredibly robust, resisting breakage even when dropped onto hard surfaces.

The X4 GND filter also boasts impressive structural hardness, preventing warping - a common issue with traditional resin filters over time, especially when not stored flat. This structural integrity ensures no distortion, even on wide-angle full-frame setups.

Each X4 GND filter features our state-of-the-art MRC16 and nanotec coatings on both sides of the optical surface. These coatings reduce surface reflection and make handling and cleaning the glass surface a breeze. The nanotec coatings also allow the X4 GND filter to glide smoothly in the holder. The edges of each X4 GND are milled smooth and coated with a protective layer for added durability.

Every X4 GND filter comes with a protective diamond case. These cases are sturdy, user-friendly, and prevent damage when stored in your bag. They also come in unique colors for easy identification. Experience the difference with the 100x150mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter, the world's sharpest and most color-neutral GND filter.
