B+W 30.5mm #102 Neutral Density (ND) 0.6 Glass Filter
A B&W 30.5mm #102 Neutral Density 0.6 Glass filter has several uses and offers the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film. They have no effect on color balance.
Neutral Density filters have four main uses
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

Comments about B+W 30.5mm #102 Neutral Density (ND) 0.6 Glass Filter:
...I've never had a B&W lens bind up on a lens--as with others...the glass is legendary, and it makes no sense to me to put a cheap filter on my Zeiss lens (in this case a Rollei 35s)...
