NiSi Square Nano IR GND Reverse 150x170mm GND16 1.2

NiSi Square Nano IR Graduated Neutral Density (GND) Reverse Filter

The NiSi Square Nano IR GND Reverse filter is specifically designed for landscape photographers to manage challenging lighting conditions during sunrise and sunset. This high-quality filter is made from premium optical glass (H-K9L) with advanced nano coating on both sides to preserve image detail and prevent color cast.

Design and Functionality

The filter features a reverse graduated neutral density design, where the darkest area is centered on the middle of the filter and gradually becomes clearer towards the top, while the bottom part remains completely clear. This design helps prevent overexposure of the skyline, especially useful when shooting scenes with intense light near the horizon.

The filter can be repositioned within the holder, allowing photographers to compose their shots precisely for optimal results.

Optical and Coating Features

• Constructed from high-quality optical glass (H-K9L) for excellent clarity and color fidelity
• NiSi Optical Nano Coating on both sides provides water and oil repellency, scratch resistance, and easy cleaning
• Infrared (IR) protection coating reduces infrared light transmission, eliminating unwanted red color casts in images taken at small apertures
• Ultra-low color cast and ultra-low reflection ensure natural color reproduction and cleaner blacks
• High definition imaging without vignetting
• Compatible with other filters without affecting coloration

Usage

This filter is ideal for balancing bright and dark areas in landscape photography, particularly during sunrise and sunset. It helps to control exposure in the sky while maintaining natural colors and details in the rest of the image.
