Neutral Density filters evenly reduce the amount of light passing thru the lens without effecting color.

Details

Neutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film, they have no affect on color balance.

They have four main uses:
  1. To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc.
  2. To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background.
  3. To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations.
  4. To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.

      Accounts for about 2 stops down-step or 1/4 ISO
