Long exposure photography
is a technique that
requires a slow shutter speed

Example of Long Exposure Photography showing light trails.
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
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.
Example of Light-Painting
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.
Water and long exposure
Long exposure particularly lends itself to blurring moving water

any object isstanding in it).
A solargraph is a long-exposure photograph which shows the path
taken by the sun across the sky. One example of this is a single six-month
exposure taken by photographer Justin Quinnell, showing sun-trails
Suspension Bridge between 19 December 2007 and 21 June 2008.

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
securely fixed in a position which won't be
