This Newest Version of Polar Pro's Neutral Density Filter features a Brand-New Glass Filter with even better Optics than its Predecessor. The New Glass-is-also-Stronger, in addition to the Glass, this Filters Frame got a Complete-Overhaul by Bulking-it-Up with more Material and Over-Molding the Glass for Higher Durability. The Filter is very Simple-to-Install, just Slide-It Right-Onto the Hero3 Waterproof Housing.
The most Common-Application the Neutral Density Filter is used for is when you want to make Moving-Things-Blurred. The GOPRO Hero3 has a Very-High Shutter Speed so often times when Moving-Fast, Nothing-is-Blurred, Creating-the-Illusion that you are not Moving-Quickly. For example when in the car the Neutral-Density Filter will Blur-the-Pavement and it creates the Illusion of Speed. Another use for the Neutral Density (ND) Filter is for Aviation, Remote Control Planes, and Shooting with Quad-Copters. The Filter Reduces the JELLO-Effect which happens when the Camera-is-Mounted to Vehicles with High Vibration.
Possibly the simplest thing to use an ND Filter for is just Toning-Down Bright Scenes. If it is really bright out the Neutral Density Filter will Reduce-some-of-the-Blown-Out Highlights and leave you will an Even-More-Crisp Video. The ND Filter comes with a Tether Cord, Protective Microfiber Storage Bag and is covered by a 180 day limited warranty.
