The GoPro HERO3 is a fantastic bit of kit, but is notorious for it's very fast shutter speed.
This can lead to problems when filming from RC helicopters, aeroplanes, or in vehicles.
Either the picture can have a 'wobble' effect, or the picture is so sharp it has no feeling of movement.
A Neutral Density Filter or (ND Filter) is used to slow down the GoPro Camera’s very high shutter speed.
The ND filter essentially tricks the camera into thinking there is less light in front of it, so the camera’s shutter
speed is slowed down to compensate for the fake lower light levels. When the camera’s shutter speed is slowed,
the objects in your video will have a slight blur motion. This means that everything that is moving in the frame will
have a slight blur to it, and everything not moving will still be in focus.
To better understand, just take a quick look at our comparison videos.
Motorsports:
An ND filter will completely transform your car, vehicle 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 super-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 jelly effect or wobble. The jelly effect can easily be corrected with our ND filter.
The ND filter will blur propellors and rotors and smooth out vibration and wobble present in your aerial videos.
Quadcopter:
In the last year filming with quad-copters has become very popular, Especially the DJI Phantom.
The common issue with these is referred to as the "jelly 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.
Bright Conditions:
An ND filter can also be used to combat over exposure in bright conditions. Much like the polarising filter, an ND filter
will prevent some of the light reaching the camera lens and help to prevent the image bleaching out in bright conditions,
when filming near bright surfaces like water and snow.
