NiSi 100x150mm Nano IR Medium Graduated Neutral Density Filter ND4 (0.6) - 2 Stop

A graduated neutral density filter works by reducing the amount of light entering the lens in a gradual manner, typically from one half of the filter to the other. This is particularly useful in landscape photography where the brightness of the sky can be significantly different from that of the foreground. The filter helps to balance the exposure between these areas, allowing for a more evenly exposed image.

The NiSi Nano IR Medium Graduated ND Filter offers several benefits. Its high-quality optical glass ensures clarity and sharpness in your images, while the Nano Coating provides water resistance and reduces reflections, which can affect image quality. Furthermore, this filter is designed to maintain true-to-life colours without introducing a colour cast, making it ideal for professional photographers who require accurate colour reproduction.

This filter is particularly well-suited for landscape photography, especially when capturing scenes with contrasting light conditions, such as sunsets or sunrises where the sky is significantly brighter than the foreground. It's also beneficial for architectural photography, allowing photographers to manage exposure when buildings or other elements extend into the sky.

Yes, the NiSi 100x150mm Nano IR Medium Graduated ND Filter can be used in conjunction with polarising filters. When stacking filters, it is important to consider the impact on exposure and potential vignetting, especially when using wide-angle lenses. However, the NiSi system is designed to accommodate multiple filters, allowing for creative control over your images.

The correct positioning of the graduated ND filter depends on the horizon line in your composition. You should align the transition line of the filter with the horizon or the bright area of your scene. It may take some experimentation to find the right placement, but adjusting the filter's position while viewing through the lens can help achieve the desired effect.

The ND4 (0.6) rating indicates that the filter reduces light by 2 stops. This means it allows only 25% of the light to reach your camera sensor, which is useful in bright conditions when you want to achieve a slower shutter speed or a wider aperture without overexposing your image. This level of density is particularly effective for managing highlights while maintaining shadow detail.

The NiSi 100x150mm Nano IR Medium Graduated ND Filter is designed to be used with 100mm filter holder systems. While the filter itself is universal in terms of optical characteristics, you will need a compatible holder and adapter ring for your specific lens diameter. This ensures that the filter can be properly positioned and used effectively with your camera setup.
