NiSi Square Nano IR Graduated Neutral Density Reverse Filter

The NiSi Reverse Nano IR Graduated Neutral Density (GND) filter is specifically designed for landscape photography, especially effective during sunrise and sunset scenes. It is crafted from high-quality optical glass (H-K9L) with advanced nano coating on both sides to preserve image detail and prevent loss of sharpness.

Filter Design and Functionality

This reverse graduated ND filter features a darkened area at the center of the filter that gradually transitions to a clearer top, while the bottom part remains completely clear. This design helps to prevent overexposure of the skyline, balancing bright and dark areas in the image effectively. The filter can be repositioned within the holder, allowing photographers to compose their shots precisely for optimal results.

Optical and Coating Features

• Constructed from premium optical glass (H-K9L) for superior clarity and color fidelity
• Nano coating on both sides provides water and oil repellency, reducing reflections and enhancing durability
• Infrared protection coating eliminates unwanted infrared light, preventing red color casts in images taken at small apertures
• Ultra-low color cast and ultra-low reflection ensure natural color reproduction
• High definition optical performance with no vignetting

Usage

Ideal for managing intense light near the horizon during sunrise and sunset, this filter balances exposure without affecting the coloration of the image. It is compatible with other filters and is optimized for use with digital camera sensors.
