The NiSi 77mm Circular Long Exposure Filter Kit features four circular ND filters the NiSi HUC PRO Nano IR Neutral Density Filter ND8 (0.9) 3 Stop, NiSi HUC PRO Nano IR ND64 CPL Multifunctional Filter, the NiSi Nano IR Neutral Density Filter ND1000 (3.0) 10 Stop and NiSi Nano IR Neutral Density Filter ND32000 (4.5) 15 Stop.  The kit allows you to get creative, control shutter speed to create motion effects and long exposures. It includes a Circular Filter Pouch for easy storage of the filters in the kit.

ND Filters creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control the depth of field and convey movement in your images.

The NiSi HUC PRO Nano IR Neutral Density Filter ND8 (0.9) 3 Stop is specially designed to reduce the amount of light entering the camera by 3 stops. This filter is made from high-quality optical glass with nano coating to prevent losing any single bit of detail. Neutral density filters do not affect the coloration of the image and the 0.9 density provides a 3 stop reduction in light from entering the lens.  The ND8 is widely used to capture water flow in seascape images and to create wider apertures when using flash outdoors.

NiSi HUC PRO Nano IR ND64 + CPL Multifunctional Filter – When shooting long exposure adding ND and a CPL together is a must, you can control reflections and also the shutter speed. But with screw-in filters is a pain, but it’s much easier if you have an integrated CPL: you don’t need to stack CPL on top of ND filters anymore, don’t add more glass in front of your lens and get the most out of one filter. With stunning performance in sharpness and no-color cast. The NiSi PRO Nano IR ND64+CPL has all the top feature of NiSi Filters: IR Coating, Nano Coating, SCHOTT Optical Glass, SLIM frame and a top performance CPL.

This NiSi Nano IR Neutral Density Filter ND1000 (3.0) 10 Stop is a neutral density (ND) filter uniformly reduces the amount of light entering the lens by 10 stops. The ND filter is helpful when the contrast between the highlights and shadows is too high to get a quality exposure. The ND Filter also can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed.  The ND1000 10 Stop is commonly used for long exposures to create the effect of cloud movement or misty water.

The NiSi Nano IR Neutral Density Filter ND32000 (4.5) 15 Stop is specially designed for landscape photographers. This filter is made from high-quality optical glass with nano coating to prevent losing any single bit of detail. Neutral density filters do not affect the coloration of the image and the 4.5 density provides a 15 stop reduction in light from entering the lens.  The ND32000 (15 Stop) is widely used to capture extreme long exposure images (usually 3-6 mins in daylight), to create effects like cloud movement or cloud softening.

The NiSi Circular Filter Pouch for 4 Filters is designed for any circular filters up to 95mm. It can be conveniently mounted on a tripod leg for easy access and use and is designed from a lightweight material that protects your filters.  The pouch can hold up to 4 filters a features filter slots that keep each individual filters safe and prevent them from scratching in the pouch.
