HOYA gray filter ND64 (6 stops) 55mm ProND

This filter has a density of ND64 (6 stops) and is suitable for lenses with a diameter of 55mm. 

The filter is made of high-quality optical glass and has a gray appearance. 

It reduces the light intensity that hits the sensor or the film without affecting the color balance.

This makes it possible to use slow shutter speeds to achieve smooth lines in e.g. waterfalls, rivers, fountains, clouds or moving vehicles.

Larger apertures are also possible for less depth of field. As a result, the subject stands out from the background, which produces a better result for portraits, for example.

Finally, the neutral density filter can be useful for cameras without adjustable shutter speed to capture successful shots in very bright environments (such as snowy landscapes or sunny sandy beaches) where overexposure would otherwise be unavoidable.
