It extends the exposure time by factor 1000 and even makes people, who may accidently walk through the image, “disappear”. This makes the neutral-density filter ND1000 excellently suitable for architectural photography. \n \nExcellent workmanship\nThe neutral-density filter has excellent optical properties. The high-quality filter, which is made of multi-coated glass, is mounted in a metal socket and can be precisely adjusted. It is transported in a protective covering, which protects the filter against harmful UV-radiation and thus considerably extents its service life.
