NiSi 150x170mm Nano IR Medium Graduated Neutral Density Filter - ND16 (1.2) - 4 Stop

A graduated neutral density filter is used to balance the exposure between the brighter and darker parts of a scene, such as when photographing landscapes with a bright sky and darker foreground. The ND16 (1.2) filter reduces light by four stops, allowing you to properly expose both the sky and the ground without overexposing the brighter areas.

The Nano Coating on the NiSi filter enhances image quality by reducing reflections and glare, which can lead to improved contrast and colour accuracy in your photos. It also makes the filter waterproof and easier to clean, helping to maintain clarity and sharpness in your images.

This filter is particularly beneficial for landscape photography, especially when capturing scenes with a noticeable difference in brightness between the sky and the foreground. It is also useful for architectural photography, as it helps to maintain detail in both the highlights and shadows, ensuring a well-balanced exposure.

The NiSi 150x170mm ND16 filter is specifically designed to be compatible with 150mm filter holder systems. While it may not fit other sizes directly, you can use step-up rings or different adapter systems if you own various sizes. However, for optimal performance and ease of use, it's recommended to use it with a compatible 150mm filter holder.

To care for your NiSi graduated ND filter, always use a lens cloth or a microfiber cloth to gently wipe the surface. If the filter is heavily soiled, use a lens cleaning solution and a soft cloth to avoid scratches. Avoid using abrasive materials and store the filter in a protective case when not in use to prevent damage.

The NiSi ND16 filter is designed to maintain true-to-life colours while reducing light. It should not significantly alter the colour balance of your images. However, it is always advisable to conduct test shots and adjust your white balance settings in post-processing if needed to achieve the desired results.

A medium graduated ND filter typically has a smoother transition between the clear and dark areas, making it suitable for scenes where the horizon is not sharply defined, such as hills or mountains. In contrast, a hard graduated ND filter has a more abrupt transition, ideal for flat horizons like the ocean or a clear skyline. Choosing the right one depends on the landscape you are photographing.
