Introducing the NiSi 100 x 100mm Nano IRND 4.5 Filter—a photographic tool designed to wield the power of a 15-stop exposure reduction. With its formidable 4.5 density, this filter casts a captivating darkness over the entire image landscape, empowering photographers to embrace wider apertures or languid shutter speeds beyond the ordinary. A realm of creative possibilities unfolds as exposure times are manipulated, or apertures are expanded, seamlessly controlling depth of field and capturing mesmerizing motion. Crucially, neutral density filters like this one maintain the image's inherent coloration, rendering them the perfect companion for diverse filter setups.

Crafted with a keen focus on digital sensors' characteristics, the NiSi 100 x 100mm Nano IRND 4.5 Filter is meticulously engineered for consistent attenuation across both visible and infrared light spectrums. Acknowledging digital sensors' heightened vulnerability to infrared light compared to conventional film, NiSi has harnessed the prowess of NiSi Optical Nano Coating—a layer that graces all surfaces of the filter. This coating dispels color casts, bequeathing images with immaculate, unadulterated blacks. Crafted from optical glass, this filter measures a slender 2mm in thickness, ensuring both crystalline clarity and precise color fidelity.

• 100 x 100mm neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
• Providing a 15-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
• Filter does not affect coloration of the image and is ideal for use with other filters.
• Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
• Nano coating provides an improved beading effect with water or oil for more efficient cleaning.
• Constructed from optical glass for clarity.
• Leatherette pouch included for storage and transport.
