Shutter speed decides whether motion looks frozen or smeared. The right value depends on how fast the subject moves and how steady you are. Use these ranges as general guides and adjust after checking your results.
Ranges by Subject
| Subject | General range | Effect |
|---|---|---|
| Fast sports, birds in flight | 1/1000 to 1/4000 | Freezes sharp action |
| Running children, pets | 1/500 to 1/1000 | Keeps fast movement crisp |
| Walking people, street | 1/250 to 1/500 | Sharp candid frames |
| Standing portraits | 1/125 to 1/250 | Avoids shake and small movements |
| Static scenes, handheld | 1/60 to 1/125 | Fine with steady hands |
| Panning with a subject | 1/30 to 1/60 | Sharp subject, streaked background |
| Flowing water, silky look | 1/4 to several seconds | Needs a tripod |
| Night cityscapes | Several seconds | Needs a tripod and a remote release |
Handheld Rule
As a loose rule, keep the shutter speed at or above one over the focal length. A 100mm lens needs about 1/100 or faster. Built-in stabilization can help by a few steps, but it does not stop subject movement.
Choosing Quickly
- Ask whether the subject moves, and how fast.
- Choose the range from the table, and set it in shutter-priority or manual mode.
- Check the aperture and ISO the camera chooses, and raise ISO if the picture is too dark.
- Take a test shot and zoom in on the screen to check for blur.
- Adjust faster for sharper action or slower for deliberate blur.
Creative Blur
- Panning: follow the subject smoothly and press the shutter without stopping the swing.
- Zoom blur: change the zoom during a slow exposure.
- Light trails: use several seconds on a tripod at night.
In bright daylight, long exposures can overexpose the shot, so use a small aperture, low ISO or a neutral density filter. Never look at the sun through the camera or lens.
Technique can buy you extra stops of sharpness. Stand with feet apart, tuck your elbows in, exhale gently and squeeze the shutter button rather than jabbing it. Use the viewfinder against your face for a third point of contact. Burst mode can also help, since one frame in a series is often sharper than the others.
Remember that light often limits you. If the scene is dim, a fast shutter speed forces a high ISO or a wide aperture, so decide which compromise suits the picture.
FAQ
Why are my pictures blurry even at fast speeds?
Check focus first. Missed focus looks like blur, and so does shaking the camera when pressing the button.
Can I use a slow shutter without a tripod?
For small amounts, yes. Brace your elbows against your body or lean on a solid surface.
The Short Version
Fast subjects need fast speeds, steady subjects allow slower ones, and creative blur needs a tripod or smooth panning. Test, zoom in and adjust.
