Long-exposure photography is used at nighttime to take interesting pictures of the roads with their road being noticeable
Long-exposure, fourth dimension-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements. Long-exposure photography captures i element that conventional photography does non: an extended period of time.
The paths of bright moving objects become clearly visible—clouds form wide bands, vehicle lights draw brilliant streaks, stars leave trails in the heaven, and h2o waves appear smooth. Merely bright objects leave visible trails, whereas night objects usually disappear. Boats in long exposures disappear during the daytime, only depict bright trails from their lights at night.
Technique [edit]
A long exposure photo of a watch in the dark. Note the advent of the second hand as information technology rotates, showing that this was a xxx-2nd exposure. The hour hand (which has just moved barely) is articulate, while the minute mitt is slightly blurry from a one-half a minute of motility.

While there is no fixed definition of what constitutes "long", the intent is to create a photo that somehow shows the effect of passing fourth dimension, exist information technology smoother waters or calorie-free trails. A xxx-infinitesimal photo of a static object and surrounding cannot be distinguished from a brusk exposure; hence, the inclusion of motion is the main factor to add together intrigue to long exposure photos. Images with exposure times of several minutes also tend to make moving people or dark objects disappear (because they are in whatever one spot for only a fraction of the exposure time), often adding a serene and otherworldly appearance to long exposure photos.
When a scene includes both stationary and moving subjects (for example, a fixed street and moving cars or a camera inside a car showing a fixed dashboard and moving scenery), a slow shutter speed can cause interesting furnishings, such as low-cal trails.
Long exposures are easiest to achieve in low-light weather condition simply tin exist done in brighter lite using neutral density filters or particularly designed cameras. When using a dumbo neutral density filter, a camera'southward auto focus will non be able to function. Information technology is best to compose and focus without the filter. Then once ane is happy with the composition, they can switch to transmission focus and put the neutral density filter back on.[ane]
Applications [edit]
Star-trail photography [edit]
A star-trail photograph uses long exposure times to capture the apparent motion of stars in the night heaven due to Globe's rotation. A star-trail photograph shows private stars as streaks across the paradigm, with longer exposures yielding longer arcs.

Star trails photographed by facing northwest.
-
A star trail photograph showing the apparent motion of stars around the north celestial pole; Polaris is the bright star near the pole, but above the jet trail.
-
The constellation of Cassiopeia over a thunderstorm.[iii]

Night photography [edit]
Long exposure: thirty sec: insect flights in the night in front of a spotlight.
A 20-2nd exposure shows car trails at twilight in the high desert, California.
A 30-second exposure shows the candlelight trails in a Romanaian cathedral.
Long-exposure photography is often used in a dark-time setting, where the lack of light forces longer exposures, if maximum quality is to be retained. Increasing ISO sensitivity allows for shorter exposures, simply substantially decreases paradigm quality through reduced dynamic range and higher noise. By leaving the camera's shutter open for an extended period of time, more calorie-free is absorbed, creating an exposure that captures the unabridged dynamic range of the digital camera sensor or film. If the camera is stationary for the entire catamenia of time that the shutter is open, a very vibrant and clear photograph can be produced.[four]
Light painting [edit]
Example of calorie-free painting
In this technique, a scene is kept very dark and the lensman or an banana takes a light source—information technology can be small penlight—and moves it nigh in patterns. The light source tin be turned off between strokes. Often, stationary objects in the scene are illuminated past briefly turning on studio lights, by one or more than flashes from a strobe light, or by increasing the aperture.[5]
Water and long exposure [edit]
A 30-second-long exposure sharply captured the still elements of this prototype while blurring the waterfall into a mist-like appearance. Debris in the swirling water in the pool forms complete circles.
A 4-second-long exposure of a gorge yields a more than misty wait.
Long exposures tin blur moving h2o so it has mist-like qualities while keeping stationary objects like country and structures sharp.[6] Varying the shutter speed tin can produce different furnishings, preserving some of the water'due south turbulence or smoothing it out entirely.[7]
Solarigraphy [edit]
A ane-year exposure, showing sun trails for the entire yr 2014. Epitome was taken in Sashegy, Buda, Budapest, Hungary.
Solarigraphy/solargraphy is a technique in which a fixed pinhole camera is used to expose photographic paper for a length of time that is typically half-dozen-months only can be as brusque every bit a few hours and last well over a yr. Depending on the length of the exposure the resulting image shows the path of the Sun across the sky[viii] both from dawn until dusk, simply as well from North to South (or vice versa) between the solstices. Each light streak in a solargraphic epitome represents ane solar day. Where calorie-free streaks are broken or missing indicates obstruction of the sun, which is caused past cloud comprehend.
Oftentimes, cameras are fabricated from upcycled aluminum or can cans which can be fabricated calorie-free-tight and are generally weatherproof for the time needed to make the exposure. Apertures usually range in fractions of a millimeter.
One example of this is a unmarried vi-month exposure taken by photographer Justin Quinnell, showing sunday-trails over Clifton Suspension Bridge between 19 December 2007 and 21 June 2008. Part of the Dull low-cal: 6 months over Bristol exhibition, Quinnell describes the piece equally capturing "a period of time beyond what we can perceive with our own vision."[8] This method of solargraphy uses a elementary pinhole camera securely fixed in a position which won't be disturbed.[viii] Quinnel constructed his camera from an empty drink tin can with a 0.25mm aperture and a single sail of photographic paper.[9]
