The next important factor to be considered while trying to achieve a perfect exposure in digital photography is shutter speed. Like I mentioned earlier, the other two are Aperture and ISO. Firstly, we’ll give a brief introduction to what the shutter is in a DSLR camera, what it comprises of, how it works before we finally go into discussing shutter speed and features associated with it.
What is a shutter in a DSLR camera?
In photography, a shutter is a device that allows light to pass for a pre-determined period, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene. The shutter is constructed such that it automatically closes after a certain required time interval. Operation of the shutter is triggered by a button called the shutter button or shutter-release button.
What is a shutter button?
In photography, the shutter button or shutter-release button is a button located mostly on the right-hand side of the DSLR camera body. When the button is pushed, the shutter opens for a pre-defined length of time; allowing light into the image sensor. During this process, an image is captured and the shutter closes afterward.
