In conditions of extreme light intensity, such
as sunshine on snowy mountains or on the beach, or when using a camcorder, ND
(Neutral Density) filters are recommended as essential. 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: To enable slow shutter speeds to be used,
especially with fast films, to record movement in subjects such as waterfalls,
clouds, cars, seas etc. 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 (ie: above ISO400) and allow it to be used
outdoors in blight situations.
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. Aperture Decrease of Filter NDx2 - 1 Stop NDx4 - 2 Stops NDx8 - 3
Stops GENERAL These filters offer both amateur and professional photographers
HOYA's famous quality at reasonable prices. They have coatings applied to both
surfaces to suppress reflection and increase light transmission. There are a few
exceptions in the special effects range which, due to the special materials used
in construction, do not have coatings applied.
