Flix Glass Prop Filter 52

This is a Standard ND8 prop filter for all Flight Flix 52 filter adapters and GoPro safe cases. How it works? An HD camera image sensor is controlled by the amount of light it senses. In normal lighting conditions, the scanning frame rate of any CMOS HD camera causes distortion and odd lines in your video. The filter tricks the camera into sensing lower light which increases the exposure value of the camera. The brighter the conditions, the stronger the filter you will require. The ND8 works well on sunny days.
