The PRO ND series is a highly neutral ND (dimming) filter manufactured by applying a special coating with vacuum deposition technology. 
This filter only reduces the amount of light without affecting the subject's color.
ND500 reduces the light intensity to 1/500 and 9 stops.

By using a high-density ND filter and dimming, a slow shutter is possible, and the effect of motion blur (motion blur *) can be intentionally added. 
You can soften the flow of the mountain stream like silk, and effectively express the speed and dynamics of moving subjects. 
In movie shooting, the background can be blurred by opening the aperture in fine weather.
* Intentionally blurring moving subjects by long exposure.
