Basically in modern DSLR photography the term exposure indicates to the time, amount and sensitivity of the light to which an image sensor will be exposed. By three things, known as remote Shutter speed, Aperture and ISO this exposure can be controlled.
In this article there is discussion done about the Shutter Speed. This is the time for which the shutter will remain open and through the lens the light will fall on the image sensor. Below are some facts about shutter speed -
· The sensor will be less exposed to the light if the speed of the shutter is fast. To capture very fast moving subjects like a panther chasing a deer or a formula one car at its top speed faster shutter speeds are often required.
· To freeze a subject fast shutter speed is one of the key things which is a quintessential part of Sports Photography or Wildlife Photography.
· Typically, in the professional DSLR bodies a highest shutter speed in an entry level to mid-level DSLR camera with flash trigger is 1/4000 which extends to 1/8000.
· For creative photography a slow speed is also a very much handy tool. It is necessary that the image sensor is exposed for a long time to capture your picture perfect image when you are at a place with low light.
· While handling a low light environment with a slow speed the main obstacle often photographers face is the blurred effect in image known as motion blur and camera shake.
· By the movement of body or parts of the body of the photographer the camera shake is caused. Though you might think that it is very little and nominal, but your high precision DSLR treats it huge like you treat the earthquake. A sturdy tripod must be used to eliminate this problem.
· When you are planning to capture photographs at night with slow and long shutter speeds a remote shutter release cable with a sturdy tripod is the best combination.
