What are some of the key uses for this Neutral Density Filter?
Motorsports: An ND filter will completely transform your auto and motorcycle images and video. Usually the extremely fast GoPro shutter speed captures every little detail of the road, or the scenery, and gives the illusion that you are not moving at all. This Neutral Density filter will slow down the shutter speed and give the road and surroundings a smooth motion blur.
Aviation: The GoPro is also notorious for the rolling shutter when filming from an airplane. Rolling shutter causes the aerial video to have a jello effect or wobble. The jello effect can easily be corrected with our ND filter. The ND filter will blur the prop and make smooth out your aerial videos.
Quad Copter: In the last year filming with a quad copter has become very popular, Especially the DJI Phantom. The common issue with these is referred to as jello effect, caused by the Gopro’s rolling shutter, high shutter speeds, and vibration. This neutral density filter is the easiest way to fix rolling shutter and smooth out your quad copter videos.
