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 ref erred 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.
