ND(NEUTRAL DENSITY) 2X 4X 8X 16X
Neutral Density filters are often ignored by photographers, but they
have several uses and offer the possibility to get otherwise
unachievable results. ND filters appear grey and reduce the amount
of light reaching the film and sensor. They have no affect on color
balance. There four main uses are:
To enable slow shutter speeds to be used, especially with fast
film, to record movement in subjects such as waterfalls, clouds,
cars, the sea, 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 (i.e., above ISO
400) and allow it to be used outdoors in bright situations.
To allow HDSLR, movie and video cameras (which have fixed
shutter speeds) to film subjects such as snow, sand or other
bright scenes which would normally cause overexposure.
