Shutter speed is how long your camera’s sensor is exposed to light when you take a picture, and it decides whether movement looks frozen or blurred. Fast speeds, written as fractions like 1/1000, freeze action, while slow speeds, such as one second or longer, let motion smear and let in more light. The values below are general rough guides, not fixed rules.
How Shutter Speed Works
Speeds are measured in seconds or fractions of a second. Each step of the usual scale roughly doubles or halves the light, which photographers call one stop. Going from 1/250 to 1/125 lets in twice as much light. Because of that link, shutter speed always trades off against aperture and ISO to keep the exposure balanced.
Common Speeds and What They Do
| Speed | Typical use |
|---|---|
| 1/2000 and faster | Fast sports, birds in flight |
| 1/500 to 1/1000 | Running people, pets, general action |
| 1/125 to 1/250 | Walking subjects, everyday handheld shots |
| 1/30 to 1/60 | Panning, indoor scenes with steady hands |
| 1/4 to several seconds | Waterfalls, light trails, night scenes on a tripod |
How to Choose a Speed
- Decide whether you want to freeze motion or show it.
- For a handheld shot, try a speed of at least one over your focal length. With a 50mm lens, that means about 1/50 or faster, and faster still if you want a safety margin.
- For moving subjects, begin around 1/500 and adjust upward if you still see blur.
- For creative blur, use a tripod and try speeds from about 1/2 second to several seconds.
- Use shutter priority mode to set the speed while the camera chooses the aperture, or switch to manual for full control.
- Check your result on the screen, zoom in, and adjust.
Avoiding Unwanted Blur
- Use a faster speed when using long lenses, since they magnify shake.
- Turn on image stabilization if your lens or body has it, and switch it off on a tripod unless the maker advises otherwise.
- Raise ISO when needed. A little noise is often easier to accept than motion blur.
- Use a remote release or short timer for long exposures.
- Brace your elbows against your body and press the button gently.
Creative Uses
Panning follows a moving subject at a slow to medium speed, such as 1/30, to blur the background while keeping the subject mostly sharp. Long exposures turn water into a silky texture and car headlights into streaks. A neutral density filter lets you use slow speeds in bright daylight.
FAQ
What shutter speed should I use in low light?
Use the slowest speed you can hold steady, raise ISO, or open the aperture. If the subject is still, a tripod lets you use a much slower speed.
Does shutter speed affect depth of field?
No. Depth of field is controlled by aperture, distance and focal length. Shutter speed affects only motion and the amount of light.
The Short Version
Fast shutter speeds freeze movement and slow ones blur it. Begin with one over your focal length for handheld shots, raise it for action, and use a tripod for long exposures. Check the result and adjust as you learn how your camera behaves.
