Long exposure photography
- Long exposure photography
Long exposure photography is a technique that requires a slow shutter speed to capture light and movement.
Technique
When an image is taken including stationary and moving subjects (for example, a fixed street and moving cars or a camera within a car showing a fixed dash-board and moving scenery) using a slow shutter speed, interesting effects, such as light trails occur.
Long exposures are easiest to accomplish in low-light conditions, but can be done in brighter light using neutral density filters or specially designed cameras.
Light-painting
While light trails at night are the most widely recognised form of long exposure photography, the same technique can be used to create light-paintings where the subject is kept dark, but the photographer moves lights about the subject.Or|date=October 2008
Water and long exposure

A solargraph is a long-exposure photograph which shows the path taken by the sun across the sky.[cite journal|journal=New Scientist|publisher=Reed Business Information|volume=200|issue=2676|date=4 October 2008|title=Watching the sun go by|author=Lucy Dodwell] One example of this is a single six-month exposure taken by photographer Justin Quinnell, showing sun-trails over Clifton Suspension Bridge between 19 December 2007 and 21 June 1008. Part of the "Slow light: 6 months over Bristol" exhibition, Quinnell describes the piece as capturing "a period of time beyond what we can perceive with our own vision."] References
