Time exposure is a photography term that refers to the length of time that the camera's shutter remains open during a single exposure. The spelling of this word is in accordance with its phonetic transcription /taɪm ɪkˈspoʊʒər/. The first syllable "time" is pronounced as "tahym" and the second syllable "exposure" is pronounced as "ik-spoh-zher". The use of phonetic transcription helps to clarify the pronunciation of words, avoiding any confusion in communication. Thus, photographers should ensure proper time exposure to capture the perfect shot.
Time exposure refers to a photographic technique used to capture moving subjects or create particular artistic effects by intentionally extending the duration of exposure. This technique involves a longer exposure time than what is typically required, allowing the camera's sensor or film to record the subject's movements throughout that period.
In time exposure photography, a camera is usually mounted on a tripod or a stable surface to avoid any unwanted shaking or blurriness. By employing a slow shutter speed, the camera records the subject's movement as it occurs over time, resulting in unique and often surreal visual effects.
One popular application of time exposure is capturing light trails produced by moving vehicles at night. By exposing the scene for a longer time, the camera records the car's lights as streaks or trails, creating a dynamic and captivating effect. Another common use is capturing images of star trails during long exposures, which reveal the paths traced by stars across the night sky.
Time exposure can also be utilized for artistic purposes, allowing photographers to experiment with abstract and creative effects. For example, when photographing moving water, a longer exposure can produce a silky smooth effect, transforming rushing streams or crashing waves into ethereal and dreamlike scenes.
Overall, time exposure in photography provides a means to manipulate time and incorporate movement into still images, resulting in visually engaging and often mesmerizing photographs.
The word "time" originates from the Old English word "timian", which means "to happen" or "to occur". It is derived from the Proto-Germanic word "timôną".

When combined, the term "time exposure" refers to a photographic technique where the camera's shutter is left open for an extended period, capturing the cumulative effect of light or motion over time.
