NiSi Square Nano IRGND Medium Graduated Neutral Density Filter 75x100mm

The NiSi Nano IR Medium Graduated Neutral Density (GND) filter is specifically designed for landscape photographers to control exposure in scenes with bright skies and darker foregrounds.

Optical Quality and Construction

• Made from high-quality environmental optical lens glass (H-K9L), not resin, ensuring superior image clarity and durability.
• Features nano coating on both sides to prevent loss of detail and reduce reflections.
• Water and oil repellent surface treatment for easy cleaning and maintenance.

Filter Characteristics

• Medium graduated density with a smooth transition from dark at the top to clear at the bottom, ideal for scenes with buildings, mountains, or other elements protruding into the skyline.
• Neutral density effect does not alter the coloration of the image.
• Infrared protection coating reduces unwanted infrared light that can cause red color casts when shooting at small apertures, restoring natural colors.
• Ultra low color cast and ultra low reflection for high definition results.
• No vignetting effect when used properly.

Usage and Flexibility

• Filter size: 75 x 100 mm, compatible with NiSi square filter holders.
• Can be repositioned within the holder to recompose the photo for optimal exposure control.
• Available with density steps of 2 and 3 stops (maximum effect).
