The variable neutral density (ND) filter is an inexpensive tool for controlling the amount of light that strikes the sensor. When attached to the front element of the lens, a rotation of this polarizer-like filter allows you to block 1 to 10-stops of light. These filters facilitate long exposure photography during daylight hours, thus allowing you to capture the blurred ebb and flow of cars, people and water during the brightest minutes of the day. A long-time tool of videographers and cinematographers, the variable ND permits access to fast apertures and slow shutter speeds when ambient light would otherwise restrict the exposure. Used here at Osceola Falls, my variable neutral density filter was attached to a 35mm lens. I set the gear on a stable tripod, used a cable-release and applied mirror lock-up to shoot a 20 second exposure at f16.
