When it is desirable to maintain a particular lens opening for sharpness or
depth-of-field purposes, or simply to obtain proper exposure when confronted with too much
light intensity, use a Neutral Density (ND)
filter. This will absorb light evenly
throughout the visible spectrum, effectively altering exposure without requiring a change
in lens opening and without introducing a color shift.
A Neutral Density filter reduces the
amount of light passing through the camera lens without changing the color of the
scene. It is especially useful in bright light conditions to help prevent
overexposure. The neutral density filter also allows proper exposure at a wider lens
opening for reduce depth-of-field to highlight a key subject by making the foreground
and/or background out of focus.
The Neutral Density filter also allows
shutter speeds to produce blurred motion effects.
Available in densities .3, .6 and .9.
