Square filters are a dynamic and adaptable tool for photographers who demand precision and versatility in their image-making process. Unlike their circular counterparts, NiSi square filters slot into a holder mounted on the lens, allowing photographers to quickly swap out different filters without unscrewing them from the lens. This system is especially beneficial for landscape and architectural photographers who often need to adjust their approach quickly in response to changing light and scenes.

Our range of NiSi square filters includes a variety of types to suit different photographic needs. Graduated neutral density filters allow for balanced exposures in scenes with a bright sky and darker foreground, by selectively darkening specific areas of the frame. Full neutral density filters enable the capture of long exposure shots even in bright conditions, perfect for creating that silky water effect or capturing movement in clouds. There are also specialised filters such as reverse grads for capturing brilliant sunsets, and colour filters for creative effects.

Each filter is crafted from high-quality optical materials, ensuring that your images retain clarity and color fidelity. The square filter system also allows for the stacking of multiple filters, providing endless combinations and possibilities to create the desired effect in-camera. This not only saves time in post-processing but also gives you more control and creativity during the shoot.

Explore our selection of square filters to find the perfect tools for expanding your creative vision and achieving breathtaking results, no matter where your photography journey takes you. Whether you’re a seasoned professional or an aspiring enthusiast, our carefully curated collection will help you capture the world as you see it.
