Neutral Density filters are used to reduce the quantity of light that reaches the sensor of the camera. They allow to decrease the shutter speed in order to achieve motion blur (waterfalls, ocean, clouds...) and/or to reduce depth of field in very bright conditions. As they are "neutral", ND filters do not affect color rendition. With Zomei Variable Density Neutral Gray filters, users can select the intensity from ND2 (1 f-stop) to ND400 (8+ f-stops) by rotating the front ring.
