These filters reduce the amount of light passing through the camera lens by 1 stop without changing the color of the scene.  They are especially useful in bright light conditions to help prevent overexposure.  Neutral Density filters also allow proper exposure at a wider lens opening for reduced depth-of-field to highlight a key subject by making the foreground and/or background out of focus.
