Improve your photography with the Starblitz neutral grey filter 1000x 58mm ND filter. The filter's main advantage is that it reduces the amount of light that ends up on the camera’s sensor, allowing you to use a longer shutter speed. It also creates beautiful photos with ghostly, blurred lights or water. Another popular feature of ND filters is that you can use a wider aperture with the same ISO sensitivity and shutter speed for a stunning depth of field effect. The Starblitz neutral grey filter 1000x 58mm ND Filter has a 58 mm filter diameter, so it's compatible with many different lenses. The ND factor of 1000 indicates a transmittance of 0.1%, so you can set up an exposure a thousand times longer.
