One of the three near important settings in photography is Shutter Speed, the other ii beingness Aperture and ISO. Shutter speed is responsible for two item things: changing the brightness of your photo and creating dramatic effects by either freezing action or blurring motion. In the following article, we will explain everything you need to know about information technology in very simple language.
Shutter speed exists because of the photographic camera shutter – which is a curtain in front end of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that has passed through your lens. Afterwards the sensor is done collecting the calorie-free, the shutter closes immediately, stopping the lite from hitting the sensor. The push button that fires the camera is too chosen “shutter” or “shutter push,” because it triggers the shutter to open up and close.
What is Shutter Speed?
Shutter speed is the
length of time
the camera shutter is open up, exposing low-cal onto the camera sensor. Substantially, it’due south how long your camera spends taking a photo. This has a few of import furnishings on how your images will appear.
When you use a long shutter speed (likewise known equally a “slow” shutter speed), you end upward exposing your sensor for a pregnant flow of time. The first big effect of it is
motion blur. If your shutter speed is long, moving subjects in your photograph will announced blurred along the direction of move. This upshot is used quite ofttimes in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer past intentionally blurring the moving wheels.
Slow shutter speeds are also used to photograph the Milky Style or other objects at night, or in dim environments with a tripod. Landscape photographers may intentionally utilise long shutter speeds to create a sense of motion on rivers and waterfalls while keeping everything else completely sharp.
On the other mitt, shutter speed tin can also be used to do just the opposite – freeze motion. If you lot employ an peculiarly fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past. If you utilise a fast shutter speed while taking pictures of h2o, each droplet will hang in the air completely sharp, which might not even exist visible to our own optics.
All of the above is achieved by only decision-making the shutter speed. In summary, quick shutter speeds freeze action, while long ones create an effect of motion when you photo moving objects.
How Shutter Speed is Measured
Shutter speeds are typically measured in fractions of a 2d when they are under a 2d. For instance, 1/4 means a quarter of a second, while ane/250 means i-two-hundred-and-fiftieth of a 2nd (or four milliseconds).
Well-nigh modern DSLRs and mirrorless cameras can handle shutter speeds of 1/4000th of a 2nd at the fastest, while some tin handle even quicker speeds of ane/8000th of a second and faster. On the other manus, the longest bachelor shutter speed on most DSLRs or mirrorless cameras is typically thirty seconds. Yous tin apply a longer shutter speed by using external remote triggers, if necessary.
Shutter Speed and Exposure
The other important effect of shutter speed is on exposure, which relates to the brightness of an image. If y’all use a long shutter speed, your camera sensor gathers a lot of lite, and the resulting photograph will be quite bright. By using a quick shutter speed, your camera sensor is only exposed to a small-scale fraction of light, resulting in a darker photo.
Still, shutter speed is non the just variable that affects the effulgence of an image. There are too Aperture and ISO, forth with the actual brightness of the scene in front of you. And so, you have some flexibility when you lot’re deciding on a shutter speed, but you demand to pick your other settings carefully.
Shutter speed can be a vital tool to capture a photo of the proper brightness. On a sunny 24-hour interval, you may need to use a fast shutter speed so that your photograph isn’t overexposed. Or, if information technology is nighttime out, a long shutter speed may be necessary to avoid a photo that is besides dark (which, in turn, could require a tripod, due to motion blur from handholding the photographic camera). For many people, this is the
main reason to adjust shutter speed: to make certain your photos are the proper brightness. Nonetheless, motion blur concerns are too very important, and should not exist overlooked.
Fast, Boring and Long Shutter Speeds
A fast shutter speed is typically any it takes to freeze action. If you are photographing birds, that may be 1/1000th 2nd or faster. However, for general photography of slower-moving subjects, you might be able to have pictures at 1/200th second, 1/100th second, or even longer without introducing move blur.
Long shutter speeds are typically above 1 2nd – at which indicate, you volition need to employ a tripod to go sharp images. You would use long shutter speeds for certain types of low-light / night photography, or to capture movement intentionally. If anything in your scene is moving when you use long shutter speeds, it volition appear very blurry.
In between, shutter speeds from 1/100th 2nd to i 2nd are still considered relatively irksome. You may not be able to handle them without introducing camera shake from your hands, particularly shut to the one-second mark.
Likewise, this strongly depends upon your lens. Some lenses, such as the Nikon seventy-200mm f/2.8, have specific prototype stabilization (also known as “vibration reduction”) technologies within the lens that can help photographers take pictures at very slow shutter speeds when manus-holding cameras, without introducing photographic camera shake. Other lenses do not accept vibration reduction, which means you need to utilise the reciprocal rule instead to determine how long your shutter speed should be without introducing blur from photographic camera shake. It is besides important that you lot know how to hold a camera.
How to Set Shutter Speed
Almost cameras handle shutter speeds automatically past default. When the camera is set to “Auto” mode, the shutter speed is selected by the photographic camera without your input (so are aperture and ISO). However, you can still set up the shutter speed manually if necessary:
- By setting the camera to “Shutter Priority” mode, yous choose the shutter speed, and the camera automatically selects the discontinuity.
- By setting the camera to “Transmission” way, you choose both shutter speed and aperture manually.
Within both of these modes, you lot tin choose to set ISO manually or automatically.
In virtually cases, we recommend letting the photographic camera select the correct shutter speed for you. Still, watch to be certain that y’all aren’t introducing too much motion blur in a photo (or freezing move that you want to exist blurred). I cover more of this in an article on camera modes, but I tend to shoot in “Discontinuity Priority” way 95% of the time, letting the camera calculate the shutter speed automatically.
How to Notice Shutter Speed
Do you know how to find what your camera shutter speed is set to? It is typically very easy to notice it. On cameras that have a height panel, the shutter speed is typically located on the peak left corner, as circled:
If your camera does non have a pinnacle LCD, like some entry-level DSLRs, you can look through the viewfinder, where you will encounter the shutter speed on the bottom-left side. And if your camera has neither a top LCD nor a viewfinder, like many mirrorless cameras, you lot tin run into your shutter speed but by looking on the back screen.
On about cameras, the shutter speed will not bear witness up directly as a fraction of a second – information technology will typically exist a regular number. When the shutter speed is longer than or equal to 1 2d, you will see something like one” or 5” (with the quotation sign to indicate a full 2nd).
If you all the same cannot find the shutter speed, set your photographic camera to “Discontinuity Priority” mode, and brand sure that y’all take turned “AUTO ISO” off. So, kickoff pointing around your camera from dark to bright areas. The number that changes will exist your shutter speed.

Shutter Speed FAQ
Beneath are some of the frequently asked questions related to shutter speed:
What is a Slow Shutter Speed?
A long shutter speed is typically effectually 1 second and longer. In comparison, a slow shutter speed can refer to a fraction of a second, such as 1/2 or ane/4.
What is a Fast Shutter Speed?
A fast shutter speed is often referred to as the shutter speed that is fast plenty to freeze action. Typically, photographers refer to modest fractions of a 2d, such equally 1/250th of a second or faster when talking about fast shutter speed.
How Exercise I Observe My Shutter Speed?
Shutter speed is often displayed on your camera’s height or rear LCD as a number or fraction. If you half-press the shutter release, then move your camera towards a brighter area, the number that changes is typically your shutter speed.
Which Shutter Speed is the Slowest?
Depending on your photographic camera, the slowest shutter speed that is allowed to use without using a remote shutter release is typically thirty seconds.
What is the Fastest Shutter Speed I tin Use on My Camera?
That depends on the camera’s capabilities. Most DSLR and mirrorless cameras can shoot every bit fast every bit 1/4000 of a second using the mechanical shutter. Some of the more than advanced cameras can shoot as fast as 1/8000 of a second with mechanical shutters, and even faster when using electronic shutters.
How is Shutter Speed Written?
Shutter speed is always written in seconds or a fraction of a 2d. For example, a 1-2d shutter speed is typically displayed equally a single number with a quote sign or a letter “s” at the terminate of information technology, such as 1″ or 1s. Whereas a fraction of a 2d such as 1/250 is typically displayed as 1/250 or merely 250 on well-nigh cameras.
What is the Best Shutter Speed?
In that location is no such thing, as it actually depends on what you are trying to achieve.
How Do I Modify Shutter Speed on My Phone?
While some smartphones allow changing shutter speed using the built-in phone app, nearly require installing a 3rd-party photographic camera app to permit irresolute the shutter speed. If you use an iPhone, endeavor out some apps similar Camera+.
