Neutral density (ND) filters are essentially gray-toned filters designed to absorb calibrated degrees of light as it passes through the lens. It could reduce the intensity
of light effectively without appreciably changing its color.
An adjustable ND filter could be adjusted from ND2 to ND32 by rotating the ring, creating different neutral density.
· Apply slow shutter speed under strong sunlight exposure .
· Reduce the amount of light and decrease the shutter speed and increase exposure time.
· Could blur the movement of pedestrian traffic and flowing water under bright lighting conditions.
· Adjustable neutral density filter could be adjusted from ND2 to ND32 freely.
