Shutter Speed is one of the three most significant parameters in photography, along with Aperture and ISO. Shutter speed is in charge of two things: adjusting the brightness of your photograph and creating dramatic effects by either freezing or blurring motion.
The camera shutter, which is a curtain in front of the camera sensor that remains closed until the camera fires, is responsible for shutter speed. The shutter opens and fully exposes the camera sensor to the light that has gone through your lens when the camera fires. The shutter closes soon after the sensor has finished gathering light, preventing light from reaching the sensor. Because it opens and closes the shutter, the button that fires the camera is sometimes known as the “shutter” or “shutter button.”

What is Shutter Speed?
The shutter speed of a camera is the time it takes for the shutter to open and expose light to the sensor. It’s basically how long it takes your camera to take a shot. This has a few significant implications for the appearance of your photographs.
When you utilise a lengthy shutter speed (sometimes referred to as a “slow” shutter speed), you expose your sensor for a lengthy time. Motion blur is the first major consequence. Moving subjects in your shot will seem blurred in the direction of motion if your shutter speed is slow. This technique is frequently utilised in vehicle and motorcycle commercials, where the spectator is given a sensation of speed and momentum by purposefully blurring the moving wheels.
Slow shutter speeds are also utilised with a tripod to shoot the Milky Way or other things at night or in weak light. Long shutter speeds are used by landscape photographers to give a feeling of motion on rivers and waterfalls while keeping everything else crisp.
Shutter speed, on the other hand, may be utilised to perform the exact opposite — freeze motion. Even fast-moving things, such as birds in flight or automobiles speeding by, can be eliminated by using a particularly fast shutter speed. When photographing water with a fast shutter speed, each droplet will hang in the air perfectly crisp, which may not even be apparent to our naked eyes.

How Shutter Speed is Measured:
All of the above may be accomplished simply by adjusting the shutter speed. In summary, while photographing moving things, fast shutter speeds freeze activity while lengthy shutter speeds give a motion effect.
When shutter speeds are less than a second, they are usually measured in fractions of a second. A quarter of a second, for example, is 1/4, whereas 1/250 is one-two hundred and fiftyth of a second (or four milliseconds).
Most current DSLRs and mirrorless cameras can shoot at shutter speeds as fast as 1/4000th of a second, and some can even shoot at 1/8000th of a second and faster. Most DSLRs and mirrorless cameras, on the other hand, generally have a maximum shutter speed of 30 seconds. If necessary, utilise external remote triggers to employ a slower shutter speed.
Shutter Speed and Exposure:
Another crucial consequence of shutter speed is exposure, which refers to an image’s brightness. When you choose a lengthy shutter speed, your camera sensor collects a lot of light, resulting in a brilliant snapshot. Your camera sensor is only exposed to a small percentage of light when you choose a fast shutter speed, resulting in a darker shot.
However, shutter speed isn’t the only factor that influences an image’s brightness. Aperture and ISO are important factors, as well as the brightness of the scene in front of you. So you have some leeway when it comes to shutter speed, but you’ll have to be careful with the rest of your settings.
Shutter speed is an important instrument for capturing a snapshot with the perfect amount of brightness. On a bright day, you might need to use a quick shutter speed to avoid overexposure. Alternatively, if it’s dark outside, a lengthy shutter speed may be required to avoid a photograph that’s too dark (which, in turn, could require a tripod, due to motion blur from handholding the camera). For many individuals, the primary purpose for adjusting shutter speed is to ensure that their images are bright enough. Motion blur problems, on the other hand, are crucial and should not be neglected.
Fast, Slow and Long Shutter Speeds:
When it comes to freezing activity, a quick shutter speed is usually required. If you’re photographing birds, this may be as rapid as 1/1000th second. However, you may be able to shoot images at 1/200th second, 1/100th second, or even longer without producing motion blur when photographing slower-moving things in general.

Long shutter speeds are often greater than one second, necessitating the use of a tripod to achieve clear photographs. Long shutter speeds are used for some forms of low-light / night photography, as well as to purposely capture movement. When you utilize lengthy shutter speeds, anything moving in your scene will seem incredibly fuzzy.
Shutter speeds of 1/100th second to 1 second are still regarded sluggish in the middle. It’s possible that you won’t be able to hold them without adding camera shaking from your hands, particularly at the one-second point.
This is also very dependent on the lens you’re using. Some lenses, like the Nikon 70-200mm f/2.8, have image stabilisation (also known as “vibration reduction”) technology built in that can let photographers shoot photos at very slow shutter rates while hand-holding their cameras without adding camera wobble. Other lenses lack vibration reduction, therefore you’ll have to rely on the reciprocal rule to figure out how long your shutter speed should be to avoid blur from camera shake. It’s also crucial that you understand how to hold a camera.
How to Set Shutter Speed:
By default, most cameras manage shutter speeds automatically. When you set the camera to “Auto,” the shutter speed is chosen by the camera without your participation (and so are aperture and ISO). If required, you may still manually adjust the shutter speed:
- Setting the camera to “Shutter Priority” mode allows you to choose the shutter speed while the camera chooses the aperture for you.
- You may choose the shutter speed and aperture manually by setting the camera to “Manual” mode.
You may opt to set ISO manually or automatically in both of these modes.
In most circumstances, it’s best to let the camera choose the best shutter speed for you. Still, keep an eye on the snapshot to make sure there isn’t too much motion blur (or freezing motion that you want to be blurred). I go into more detail about this in an essay on camera modes, but I shoot in “Aperture Priority” mode 95 percent of the time, letting the camera figure out the shutter speed on its own.
How to Find Shutter Speed:
Do you know how to find out what shutter speed your camera is set at?
It is usually extremely simple to locate. On cameras with a top panel, the shutter speed is usually found at the top left corner, as shown in the diagram:
If your camera does not have a top LCD, such as certain entry-level DSLRs, you may check the shutter speed via the viewfinder, which is located on the bottom-left side. If your camera, like many mirrorless cameras, does not have a top LCD or a viewfinder, you may check your shutter speed by glancing at the rear screen.
The shutter speed is usually shown as a standard number rather than a fraction of a second on most cameras. You’ll notice anything like 1” or 5” if the shutter speed is longer than or equal to one second (with the quotation sign to indicate a full second).
If you still can’t discover the shutter speed, switch your camera to “Aperture Priority” mode and make sure “AUTO ISO” is turned off. Then begin directing your camera around the room, from dark to light places. Your shutter speed will be the number that changes.
