Neutral Density (ND) filters are commonly ignored by photographers, but actually have several uses and can help you achieve otherwise unobtainable effects. ND filters work by creating a reduction in light that is neutral and equal for the sensor area. Some of the uses for ND filters are to decrease depth of field, effectively allowing larger apertures to be used, allowing better separation of subject and background. They also allow slower shutter speeds (which would normally cause over-exposure) to be used to record movement in subjects such as moving cars, waterfalls, etc.
