Instead of changing exposure over a short area, this filter spreads the gradation over a wider range, helping photographers create a smoother and less noticeable transition between a bright sky and a darker foreground.\u003c\/p\u003e\n      \u003cp\u003eThis design is especially effective in landscapes where the horizon is uneven, such as mountain ranges, valleys, forests, and layered terrain. In these scenes, a standard Soft or Hard type may create a transition that feels too obvious, while Long Soft allows the brightness to fall more gradually and more naturally across the frame.\u003c\/p\u003e\n      \u003cp\u003eIt was developed in response to requests from photographer Mamoru Watanabe, who is known for his long-term Mt. Fuji photography. In practical use, it is highly suitable for landscape photographers who want strong light control without making the gradation line visible in the final image.\u003c\/p\u003e\n      \u003cp\u003eLong Soft GND can also be used effectively in combination with a Switch Holder and a second lighter ND or GND filter. This makes it possible to fine-tune the darker area only where necessary, which is especially useful in mountain scenes or sunrise conditions where the light transition is complex.\u003c\/p\u003e\n      \u003cp\u003eLike other premium KANI square filters, this model uses high-quality German B270 optical glass with double-sided ultra-precision polishing to maintain excellent flatness and image quality. The advanced Premium low-reflection coating helps suppress flare and internal reflections, while the water-, oil-, and dust-resistant surface allows fast cleaning during outdoor shooting.\u003c\/p\u003e\n      \u003cp\u003eVisible light transmission remains very stable, and color cast is kept to a minimum even in long exposure photography, making it a reliable option for photographers who require both natural tonality and strong optical performance.\u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-features\"\u003e\n      \u003ch3\u003eKey Features\u003c\/h3\u003e\n      \u003cul\u003e\n        \u003cli\u003eExtended gradation for an exceptionally natural exposure transition\u003c\/li\u003e\n        \u003cli\u003eIdeal for mountains, forests, valleys, and uneven horizons\u003c\/li\u003e\n        \u003cli\u003eHelps avoid visible gradation lines in the final image\u003c\/li\u003e\n        \u003cli\u003eUseful alone or in combination with other GND \/ ND filters\u003c\/li\u003e\n        \u003cli\u003ePremium low-reflection coating reduces flare and internal reflection\u003c\/li\u003e\n        \u003cli\u003eGerman B270 optical glass with ultra-precise double-sided polishing\u003c\/li\u003e\n        \u003cli\u003eWater-, oil-, and dust-resistant protective coating\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-sample\"\u003e\n      \u003ch3\u003eSample Photos\u003c\/h3\u003e\n      \u003cdiv class=\"kani-sample-grid\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/Long_soft.avif?v=1775812697\" alt=\"Long Soft Sample 1\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/Long_Soft_GND_Comparison_130114b1-fad3-4d32-8895-9db237f66835.jpg?v=1775812713\" alt=\"Long Soft Sample 2\"\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Soft --\u003e\n  \u003cdiv id=\"c2\" class=\"kani-content\"\u003e\n    \u003cdiv class=\"kani-top\"\u003e\n      \u003cdiv class=\"kani-left\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/Premium_Soft_GND_1.5.jpg?v=1775805491\" alt=\"Soft GND\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"kani-right\"\u003e\n        \u003ch3\u003eSize \u0026amp; Density\u003c\/h3\u003e\n        \u003cp\u003e100×150mm\u003cbr\u003e0.6 \/ 0.9 \/ 1.2 \/ 1.5 \/ 1.8\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-desc\"\u003e\n      \u003ch3\u003eSoft GND\u003c\/h3\u003e\n      \u003cp\u003ePremium Soft GND is one of the most versatile filters in the KANI GND range. It is designed with a smooth and natural gradation that gently reduces brightness in the sky while preserving a realistic and balanced transition toward the foreground. This makes it particularly effective for sunrise, sunset, dawn light, and many general landscape scenes where the brightness difference is noticeable but not extreme.\u003c\/p\u003e\n      \u003cp\u003eBecause the transition is gradual, Soft GND works especially well in landscapes with slightly uneven horizons, such as mountains, coastlines, lakes, grasslands, and countryside scenes. It helps reduce the risk of visible filter lines, which is one of the most important factors when aiming for a natural-looking image.\u003c\/p\u003e\n      \u003cp\u003eThis filter is suitable not only for dramatic sunrise and sunset photography, but also for daytime landscape shooting when the sky is significantly brighter than the land yet the sun itself is not inside the frame. It can also be combined with ND filters to control both brightness and shutter speed, making it useful for smoothing water, clouds, and atmospheric movement.\u003c\/p\u003e\n      \u003cp\u003eKANI’s Premium coating minimizes reflections between the ND area and the clear area, helping preserve contrast and clean image rendering. German B270 optical glass and ultra-precision polishing provide high flatness and dependable sharpness across the frame.\u003c\/p\u003e\n      \u003cp\u003eVisible light transmission is very stable and color cast is kept extremely low, even during longer exposure photography. The strong protective coating also repels water, oil, and dust, allowing the filter to be cleaned quickly with a regular cloth in practical shooting situations.\u003c\/p\u003e\n      \u003cp\u003eFor photographers who want a reliable everyday GND filter with the most natural look, Soft GND is one of the best starting points in the system.\u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-features\"\u003e\n      \u003ch3\u003eKey Features\u003c\/h3\u003e\n      \u003cul\u003e\n        \u003cli\u003eSmooth and natural gradation for general landscape photography\u003c\/li\u003e\n        \u003cli\u003eIdeal for sunrise, sunset, coastlines, lakes, and mountain scenes\u003c\/li\u003e\n        \u003cli\u003eHelps balance bright skies without harsh visible transition lines\u003c\/li\u003e\n        \u003cli\u003eWorks well together with ND filters for long exposure shooting\u003c\/li\u003e\n        \u003cli\u003ePremium low-reflection coating reduces flare and improves contrast\u003c\/li\u003e\n        \u003cli\u003eGerman B270 optical glass with excellent flatness and clarity\u003c\/li\u003e\n        \u003cli\u003eWater-, oil-, and dust-resistant protective coating\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-sample\"\u003e\n      \u003ch3\u003eSample Photos\u003c\/h3\u003e\n      \u003cdiv class=\"kani-sample-grid\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/Soft_GND_0.9-2_8e897fe0-c8de-4ca5-bd04-191c0d91fdce.jpg?v=1776064883\" alt=\"Soft GND Sample 1\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/SOFT_0.9_-6_e61abc8d-2d3f-4ccc-adf4-76f4ce48a4c5.jpg?v=1776064839\" alt=\"Soft GND Sample 2\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/SOFT_0.9_CPL_571c30a8-3903-465a-ba05-d485646391d5.jpg?v=1776064839\" alt=\"Soft GND Sample 3\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/SOFT_0.9_-_7_750e1034-84f8-4854-80bc-2c6410952ad9.jpg?v=1776064839\" alt=\"Soft GND Sample 4\"\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Medium --\u003e\n  \u003cdiv id=\"c3\" class=\"kani-content\"\u003e\n    \u003cdiv class=\"kani-top\"\u003e\n      \u003cdiv class=\"kani-left\"\u003e\n        \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0688\/9648\/9771\/files\/Medium_GND_0917f291-4c83-4e1c-a131-cb7b58cc19cb.jpg?v=1775805491\" alt=\"Medium GND\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"kani-right\"\u003e\n        \u003ch3\u003eSize \u0026amp; Density\u003c\/h3\u003e\n        \u003cp\u003e100×150mm\u003cbr\u003e0.6 \/ 0.9 \/ 1.2\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"kani-desc\"\u003e\n      \u003ch3\u003eMedium GND\u003c\/h3\u003e\n      \u003cp\u003ePremium Medium GND is designed with an intermediate 3cm transition area, sitting between the wider spread of Soft GND and the tighter transition of Hard GND. It is made for photographers who need stronger control than a Soft type, while still keeping a more natural blend than a traditional Hard type.\u003c\/p\u003e\n      \u003cp\u003eThis makes Medium GND especially useful in scenes where the horizon is visible but not perfectly flat, such as rolling hills, distant mountain lines, city skylines, or mixed land-and-sky compositions. In these cases, Soft may feel too weak while Hard may feel too abrupt. Medium provides a practical balance between both approaches.\u003c\/p\u003e\n      \u003cp\u003eIt is one of the most adaptable options for photographers who want a single filter that can handle a wide range of real-world outdoor conditions.

It is a highly creative filter that combines the function of a half ND with a subtle sky-enhancement effect.\u003c\/p\u003e\n      \u003cp\u003eLike KANI’s standard Dual Purpose Filter, this model can provide two different styles of result depending on the insertion direction, allowing it to behave in both Soft and Hard orientations. This makes it useful in a wider range of sky conditions than a conventional color filter.\u003c\/p\u003e\n      \u003cp\u003eUnlike the conventional Dual Purpose 0.75, this filter uses a gentler ND 0.6 density. This is important because it allows the sky tone to become richer without appearing unnaturally dark or heavily colored. Slightly hazy blue skies become more vivid, while nearly white skies can gain a natural and moderate blue appearance.\u003c\/p\u003e\n      \u003cp\u003eIt is also useful in situations where a circular polarizer may produce uneven polarization in the sky. Because the blue enhancement is built into the filter itself, it can help create a cleaner and more controlled result in these conditions.\u003c\/p\u003e\n      \u003cp\u003eAs this filter uses a special color coating, its reflection characteristics differ from those of the standard Dual Purpose Filter. In strong backlight or when the sun is directly in the frame, reflections may occur more easily, so careful positioning is recommended.\u003c\/p\u003e\n      \u003cp\u003eFor photographers who want
