Photographing solar eclipses and ultra-bright light sources can be extremely dangerous. This filter reduces light values by 9 stops to less than 1/500th of its original intensity and allows safe photography.
It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible. Hoya ND400 filter is brilliant for landscape photography in daylight to achieve surreal images with moving clouds or water as the element.
