Neutral density filter designed for shooting the camera with GoPro "bare" or in frame "Frame", i.e. without using a waterproof case. This filter has different uses. When filming fast motion, it slows down the camera's shutter, triggering the effect of fast motion blur. During very bright days, the picture and the blues are toned. The most popular application of the ND filter is smoothing the video when filming in conditions of strong vibrations, e.g. when driving a car or flying a drone (quadrocopter) - the camera reduces the speed of the shutter again, smoothing the movement. The filter is light (10 grams) but strong and well suited to the camera. Provides additional protection when filming without the use of a protective case.
