In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. Shutter speed is most commonly measured in fractions of a second, like 1/200 seconds or 1/1000 seconds. Some high-end cameras offer.Shutter speed as fast as 1/8000 seconds. But, shutter speed can extend to much longer times, generally up to 30 seconds on most cameras.
A long shutter speed is typically around 1 second and longer. In comparison, a slow shutter speed can refer to a fraction of a second, such as 1/2 or 1/4.A fast shutter speed is often referred to the shutter speed that is fast enough to freeze action. Typically, photographers refer to small fractions of a second, such as 1/250th of a second or faster when talking about fast shutter speed.
Shutter speed is often displayed on your camera's top or rear LCD as a number or fraction. If you half-press the shutter release, then move your camera towards a brighter area, the number that changes is typically your shutter speed.
Shutter Speed is the length of time your camera shutter is open, exposing light onto the camera sensor. Essentially, it's how long your camera spends taking a photo. ... shutter speed : 5 seconds (a long shutter speed ). On the other hand, shutter speed can also be used to do just the opposite – freeze motion. Found this on the internet.
