ND filter is the abbreviation for neutral density
filter. The ND filter is used to achieve a uniformly
moderate darkening of the image. In addition, it gives
the image a uniformly neutral grey colour so that the
colour rendition cannot be altered.
An ND filter makes the subject darker by several guide
values thus preventing over-exposed images.
Frequent applications for ND filters include taking
shots with blur effects or of running water under
ND filters are used with various degrees of darkening,
depending on the prevailing light conditions for the
desired aperture and exposure time.
