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

Long exposure particularly lends itself to blurring moving water (particularly effective for waterfalls or for the sea at dusk if any object isstanding in it).Or|date=October 2008

olargraphy

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." This method of solargraphy uses a simple pinhole camera securely fixed in a position which won't be disturbed.
