The Hero Session is amazing for its long battery life, ease of operation and durability. However, there is no easy way to attach much needed filters, such as a UV or Neutral density, to the camera. Our solution a silicone sleeve that surrounds the camera and firmly holds the pre-installed filter in front of the lens. The Neutral Density filter is designed for reducing light in bright conditions, as well as reducing the camera's shutter speed. While filming in bright conditions, the ND filter will reduce excess bright light and reduce overexposure and blown out video. The Filter will also reduce the shutter speed creating a blur motion. It also fixes the common "Jell-O Effect" or wobble Commonly associated with RC Planes/quadcopters, as well as Motorsports.
