The NiSi 72mm Circular Waterfall Filter Kit features four circular filters the Ti Enhanced CPL Circular Polarizer Filter (Titanium Frame) and NiSi HUC PRO Nano IR ND64 CPL Multifunctional Filter. The kit is perfect for shooting waterfalls and it includes a Circular Filter Pouch for easy storage of the filters in the kit. NiSi Ti Enhanced CPL Circular Polarizer Filter (Titanium Frame) helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage. The NiSi Ti Enhanced CPL Circular Polarizer Filter (Titanium Frame) has enhanced colour compared to a standard CPL which increases the saturation of the scene when used. 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-colour 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. 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.
