Ever visited railway tracks? If you have, then you would have seen a boom-barrier that stops the cars from crossing the paths when there is an incoming train. And once the train has passed, the cars once again start to cross the tracks. You must be thinking that why we are discussing railway tracks in a post of Photography? But how does it answer our question of What is Shutter Speed in DSLR? Well, it’s not all irrelevant!
The Shutter in a DSLR works as a boom-barrier for the camera. When a photo is clicked, it’s the removal of the shutter so that the camera can record and when the shutter closes the camera again stops recording. In simpler terms, the shutter is the wall between the sensor of a camera and the light that passes through the sensor.
What is Shutter Speed?
Now that we have discussed shutter, it will be easy to understand the shutter speed. How fast or slow a shutter opens and closes, determines the pace of the shutter. Naturally, it is the time taken by a camera to take a photograph.
Long shutter speed leads to the exposure of light to the sensor for a longer time. This results in motion blur. Secondly, it creates a blur in the direction of motion of the object.
Fast Shutter Speed, on the other hand, is used to perform the freezing effect; subsequently, it means capturing an object without any blur.
Capturing a Fast car while drifting, or a snowflake during snowfall, all can be achieved by just controlling the Shutter Settings.
Where To Find It?
Most of the cameras have ‘Auto Mode’ which handles the Shutter Speed automatically, but this setting can also be manually set. All one has to do is select the option ‘Shutter Priority’ which allows the user to choose the rate of the shutter of preference.
While the ‘Manual Mode’ allows selecting both shutter speed and aperture manually. But “ISO” can be chosen both manually or automatically in the above modes.
Selecting “Auto Mode” is always considered to be the best setting as it hep to choose the aptest configuration for users. This is primarily a helpful setting for new users. As for choosing shutter speed can be a hassle for some due to vast settings available.
We know how to find the settings for shutter speed. But how does one set the speed? An entry-level DSLR’s Shutter Speed can be seen in the bottom left side through the viewfinder. Whereas, it can be seen on display in Mirrorless Cameras.
If still, Shutter Speed is not visible then, switch to “Aperture Mode” and also make sure to turn off the ‘Auto ISO’. And aim towards the bright areas form the dark areas; the numbers fluctuating are your shutter speed.
Shutter Speed is measured in the fraction of seconds. Most of the DSLR’s can perform 1/4000th of a second, whereas, some cameras can handle 1/8000th of a second and faster. In DSLR’s and Mirrorless cameras, 30 seconds is the most extended available shutter speed. Furthermore, it can be extended by using external remote triggers.
Exposure And It’s Relevance
As we are aware of the fact that, the shutter is the wall between the sensor and light. Also, we know that long shutter allows more light to pass through while the fast shutter setting is the opposite of it. More light will result in brighter Photos which is beneficial while taking photos in dim lights.
Whereas, the fast shutter will provide dark photos as it only exposes the sensor for a short period. The Shutter Speed of a camera along with the ISO and Aperture settings is responsible for the brightness of the photos.
Types Of Shutter Speed
There are mainly three types of shutter speed.
1/1ooth of a second to 1 second is considered to be the pace of the long shutter. It is recommended to use a tripod. But in long shutter speed, a moving object will be captured in motion blur.
The rate which is used to freeze action is called a ‘Fast Shutter Speed’. For animal photography 1/1000th of a second or above. But for general photography 1/200th or 1/100th of a second is fine. But this component also depends upon the type of lens one is using.
The pace of the shutter in between 1/100th of a second and one second is the zone of the slow shutter speed.
Difference Between Mechanical And Electronic Shutter
The shutter is a physical instrument that moves up and down inside a camera. However, the shutter used in smartphones is called an ‘Electronic Shutter’. The electronic shutter does not move up and down like a traditional shutter but instead gives an automatic command to the camera of the phone, telling when to record and when to stop.
The electronic shutter allows the camera to shoot even faster speeds. But it’s not all win-win with the electronic shutter. They might shoot at faster speeds, but they also add more noise in the pictures, which result in the reduced quality of photos.
A camera might only capture a single movement of an object, but with different shutter speeds, a sense of motion can be generated in the photos. The complete understanding of the Shutter can introduce a lot more opportunities to a photograph.
