NiSi Square Nano IR Hard Graduated ND Filter 100x150mm GND8 0.9

NiSi Nano IR Hard Graduated Neutral Density Filter

The NiSi Nano IR Hard Graduated Neutral Density (GND) filter is specially designed for landscape photographers. It is made from high-quality optical glass (H-K9L) with nano coating on both sides to preserve fine details and prevent loss of image quality. This filter features a hard transition between the dark and clear areas, making it ideal for scenes with a clearly defined boundary between bright and dark regions, such as the horizon line or the boundary between sea and sky.

Key Features

• Constructed from premium optical glass for superior clarity and color fidelity
• Hard-edge graduated neutral density filter darkens bright areas (e.g., skies) while leaving other parts unaffected
• Does not affect image coloration, allowing use with other filters
• Repositionable in the filter holder for optimal composition
• Infrared protection coating to eliminate unwanted infrared light and restore natural colors, especially when shooting at small apertures
• Ultra-low color cast and ultra-low reflection
• No vignetting
• High resolution performance
• Nano coating on both sides provides water and oil repellency

Usage

The hard GND filter is best used when there is a distinct separation between bright and dark areas in the scene. It is particularly effective for balancing exposure in landscapes with a clear horizon or defined boundary between sky and sea. The filter can be slid and repositioned within the holder to achieve the desired effect and composition.
