In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light when taking a photograph.
The amount of light that reaches the film or image sensor is proportional to the exposure time. 1⁄500 of a second will let half as much light in as 1⁄250.

Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects.
An extended exposure can also allow photographers to catch brief flashes of light, as seen here. Exposure time 15 seconds.
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.

The distance range in which objects appear clear and sharp, called depth of field, can be adjusted by many cameras. This allows a photographer to control which objects appear in focus, and which do not.
