KANI Premium GND Filter (170x190mm)
The KANI 170×190mm Graduated ND (GND) filter series is designed for professional landscape photographers who require precise exposure control in high dynamic range scenes such as sunrise, sunset, seascapes, mountain landscapes, and other situations where the brightness difference between sky and foreground is too great to capture naturally in a single exposure.
By controlling only the bright portion of the frame, these filters help create a more balanced exposure directly at the time of shooting, reducing the need for excessive post-processing and making it easier to preserve a natural look in the final image. The 170×190mm size also provides generous coverage, making it suitable for large holder systems and ultra-wide compositions where consistent gradation across the frame is important.
Each filter is manufactured using high-quality German SCHOTT B270 optical glass and finished with KANI’s advanced Premium coating technology. This combination delivers excellent flatness, high visible light transmission, reduced reflections, minimal color cast, and dependable performance even in demanding backlit scenes or long exposure photography. In addition, the water-repellent, oil-resistant, and dust-resistant protective coating makes cleaning easier and supports practical outdoor use in changing weather conditions.

Soft GND
Premium Soft GND is designed with a smooth and gradual transition between the ND area and the clear area, making it one of the most versatile filters in landscape photography. It is especially effective when photographers want to reduce the brightness of the sky while keeping the transition into the foreground natural and unobtrusive.
Because the gradation is gentle, this type is particularly suitable for scenes with uneven or irregular horizons, such as mountain ranges, forests, valleys, lakes, and rolling countryside. In these situations, a harder transition can easily look artificial, while Soft GND helps maintain a realistic tonal flow throughout the image.
Soft GND is widely used during sunrise and sunset photography, but it is also highly practical in daytime conditions whenever the sky is noticeably brighter than the land. It can also be combined with solid ND filters for long exposure photography, allowing photographers to control sky brightness while capturing smooth water, cloud movement, or atmospheric motion with a balanced overall exposure.
Built with German SCHOTT B270 optical glass and KANI’s Premium low-reflection coating, the filter provides excellent optical flatness, high visible light transmission, minimal color cast, and dependable clarity even in difficult lighting conditions. The protective outer coating also helps resist water, oil, and dust, making the filter practical for field use.
Key Features
- Smooth and gradual transition for natural exposure blending
- Ideal for mountains, forests, valleys, lakes, and uneven horizons
- Helps reduce bright skies without visible transition lines
- Highly versatile for sunrise, sunset, and daytime landscapes
- Works effectively in combination with ND filters for long exposure photography
- Premium low-reflection coating reduces flare and internal reflections
- German SCHOTT B270 optical glass for high clarity and excellent flatness
- Water-, oil-, and dust-resistant protective coating for outdoor use

Medium GND
Premium Medium GND is designed to provide a balanced transition between Soft and Hard types, making it an excellent choice for photographers who want stronger control than a soft gradation while still maintaining a natural look in the final image. It offers a practical middle ground that works well in a wide range of landscape situations.
This type is particularly useful when the horizon is partially defined but not perfectly flat, such as coastal areas with varied terrain, low mountain ridges, urban skylines, and rolling landscapes. In these scenes, Soft GND may be too gentle, while Hard GND may appear too abrupt. Medium GND provides better separation between bright sky and darker foreground without creating an obvious line.
Because of this balanced character, Medium GND is often regarded as one of the most versatile options in the graduated filter lineup. It gives photographers more decisive exposure control while remaining flexible and forgiving in composition, especially when light conditions change quickly during sunrise or sunset.
As with the rest of the series, the filter is made from high-quality SCHOTT B270 optical glass and finished with KANI’s Premium anti-reflection coating. This helps maintain excellent clarity, high flatness, minimal color shift, and strong resistance to flare, ghosting, water, oil, and dust in outdoor conditions.
Key Features
- Balanced transition between Soft and Hard gradation styles
- Ideal for partially defined horizons, skylines, and rolling landscapes
- Provides stronger sky control than Soft GND while staying natural
- Helps avoid the abrupt look associated with harder transitions
- Highly versatile for changing light conditions during landscape photography
- Premium anti-reflection coating reduces flare and ghosting
- German SCHOTT B270 optical glass for high transparency and flatness
- Protective coating resists water, oil, and dust for field durability

Hard GND
Premium Hard GND is designed for scenes where the horizon line is clear and relatively flat, and where strong control of sky brightness is needed. It provides a more defined transition than Soft or Medium types, making it ideal for photographers working in high-contrast situations where precise exposure separation between sky and land is required.
This filter is especially effective for seascapes, open plains, coastal scenes, and wide horizon landscapes where the boundary between sky and foreground is straight and uninterrupted. In such scenes, Hard GND allows the upper part of the frame to be controlled more decisively, helping preserve detail in darker foreground areas without overexposing the sky.
It is also useful in strong daylight, backlit scenes, and situations where the brightness difference is too extreme for a gentler transition to be effective. Even with its stronger effect, KANI’s carefully refined gradation design helps maintain a more natural appearance than many traditional hard-edge filters.
The use of SCHOTT B270 optical glass and Premium low-reflection coating ensures excellent optical quality, reduced flare, minimal blue cast during long exposure photography, and dependable performance in demanding outdoor environments.
Key Features
- Sharper transition for stronger exposure control
- Best suited for flat, clearly defined horizons
- Ideal for seascapes, open landscapes, and coastal scenes
- Helps preserve detail in darker foregrounds under bright skies
- Effective in high-contrast, bright daylight, and backlit conditions
- Premium coating minimizes reflections, flare, and ghosting
- German SCHOTT B270 optical glass for excellent image clarity
- Protective surface resists water, oil, and dust during field use

Reverse GND
Premium Reverse GND is specifically designed for sunrise and sunset photography, where the brightest light is concentrated close to the horizon line rather than at the top of the frame. Unlike standard graduated filters, Reverse GND places its strongest density around the center and gradually becomes lighter toward the upper area.
This structure closely matches the natural distribution of light during these times of day, making it highly effective for controlling the intense brightness around the sun while preserving detail in both the sky and the foreground. As a result, photographers can achieve a more balanced and dramatic image directly in-camera.
Reverse GND is especially useful for seascapes, coastal scenes, and wide landscapes where the sun is positioned near the horizon and a normal Soft or Hard GND cannot adequately control the brightest central region. It is one of the most important filter types for photographers who regularly shoot sunrise and sunset compositions.
The filter is made using German SCHOTT B270 optical glass and KANI’s Premium coating technology, delivering high visible light transmission, excellent flatness, reduced internal reflections, minimal color cast, and reliable outdoor durability.
Key Features
- Strongest density concentrated at the horizon line
- Designed specifically for sunrise and sunset photography
- Matches natural light distribution near the sun
- Helps preserve detail in both sky and foreground
- Ideal for seascapes, coastal scenes, and wide horizons
- Premium low-reflection coating reduces flare and ghosting
- German SCHOTT B270 optical glass for excellent optical performance
- Minimal color cast with protective water-, oil-, and dust-resistant coating

Wide Center GND
Premium Wide Center GND is designed to control strong light concentrated around the central area of the frame, especially during sunrise and sunset when the most intense brightness is located near the horizon. Unlike standard GND filters that affect a broader upper portion of the image, this type focuses the density more precisely on the area that needs control most.
This makes it especially useful when photographers want to reduce the brightness around the sun without unnecessarily darkening the upper sky or surrounding parts of the composition. The result is a more natural exposure balance and a cleaner, more realistic final image, particularly in scenes where only the center area requires correction.
Wide Center GND is well suited to horizon-based compositions, sunrise and sunset scenes, and situations where strong central light would otherwise make it difficult to preserve detail and tonal balance. It offers more targeted adjustment than a conventional graduated filter while remaining intuitive to use in the field.
The filter uses SCHOTT B270 optical glass and KANI’s Premium low-reflection coating to provide excellent transmission, high flatness, minimal color shift, and strong resistance to flare, ghosting, water, oil, and dust.
Key Features
- Focused gradation designed to control strong central light
- Ideal for sunrise and sunset compositions near the horizon
- Helps avoid unnecessary darkening of the upper sky
- Provides natural exposure balance in horizon-based scenes
- Excellent for compositions where only the center needs adjustment
- Premium anti-reflection coating reduces internal reflections and flare
- German SCHOTT B270 optical glass for high clarity and flatness
- Durable water-, oil-, and dust-resistant protective surface
