Tiffen 58mm Neutral Density 0.9 Filter

Eliminates overly bright, washed-out images Balances exposure Controls depth of field 58mm diameter For use with F-stop 3 on a manual camera; for all film types, color or black and white

Reduces the amount of light passing through the camera lens without changing the color of the scene. This filter is especially useful in bright light conditions. Allows proper exposure at a wider lens opening when reducing depth of field to highlight a key subject by making the foreground and/or the background out of focus. A slower shutter speed can be used to produce blurred motion effects.
