What is an ND Filter?

An ND filter, or neutral density filter, is a type of optical filter that reduces the amount of light entering a camera lens. This can be useful in situations where the photographer wants to use a slower shutter speed or a wider aperture without overexposing the image. ND filters are also often used in astrophotography to reduce the brightness of stars and other celestial objects.
