Polarpro 77mm ND16 QuartzLine Neutral Density Filter

Neutral Density Filters have an evenly distributed coating throughout the lens that provides light filtration by a certain degree of strength. The strength of the filter can be referred to by f-stops.

They range from 3-stops which filters out about half of the available light to 16.6-stops which let through only 1/32,000ths.
