Breathe new life into your photos with the Starblitz neutral grey filter 1000x55mm ND filter. The most notable feature of the ND (neutral-density) filter is that it reduces the light intensity coming through the lens, allowing you to work with longer shutter speeds. It also captures striking photos of objects in motion. Another neat bonus of all ND filters is that you can use a wider aperture for a stunning depth of field effect. The Starblitz neutral grey filter 1000x55mm ND Filter features a 55 mm filter diameter, making it compatible with a wide range of different lenses. The ND factor of 1000 indicates a transmittance of 0.1%, so you can set up an exposure a thousand times longer.
