A very essential component of camera to help the sensor capture images within a given time frame along with the ability to slow and fast it’s speed in order to generate user defined snaps. Basically, shutter is a part that is planted in front of the sensor that shuts down with a determined period of time by the user manually or by the camera automatically according to the lighting condition. This component holds multiple attributes like freezing motion and lets the light pass through it to the sensor in a tiny or massive amount. Let’s discuss elaborately how it works.

Complete  Guidelines to Learn all about Shutter Speed 



Obviously, shutter is controlled by a dial called "Command Dial" outside the body of a camera. User can set it by its own choice or let the camera to choose for a better shutter speed for an image that going to be captured. During which the shutter remains open until it's captured for a specified period of time which a photographer defines. It is symbolized as (1/something) in camera setting, for example 1/640. In this example, 1/640 means shutter releases within six hundred and fortieth frame of a second which is much faster.     
  
Talking about its functions or attributes about which I mention above, first property of shutter release is to freeze the motion happening within the boundary of a camera’s eye. Less shutter mean camera would not be able to capture the motion accurately and fast shutter means camera will show its efficiency to capture the motion in sharp by releasing the shutter just in no time. Picture beneath will elaborate it’s mechanism behind.

Take a look at picture above that clearly shows no visible motion at 1/500 because it has been captured by setting up the camera in a fast shutter speed of 1/500, five hundredth of a second which is more than blink of an eye. While in the last box, picture shows the mobility and motion in it because it was taken reducing the shutter speed to 1/2 of a second which is very slow speed of a shutter. Shooting in sunlight tends shutters to increase automatically on Auto Mode. But in Manual Mode, you can reduce it manually but it can cause picture to capture over-exposed. Shutter can be adjusted using command dial. User can also set a camera to Shutter Mode by setting the Mode dial to “S” (Nikon) and “Tv” (Canon). Fast shutter speed literally captures the motion but it only can be done when light conditions are perfect. If you need to capture motion then daylight or harsh sunlight condition should be preferred. Low-light conditions will not give the same outcomes as shot in sunlight. Shooting in low light needs external flash guns or additional light setup to create the whole scenario illuminated then you can caputure picture of a fast moving object. If you’re shooting a fast moving object and want to capture it smoothly like no motion visible, then first you need to set the Auto Focus Mode to AF-C (Continuous). This option continuously focuses the subject in motion that can help user to accurately focus while capturing photo.
