Camera shake blurs the whole picture in a streak or double image, while missed focus leaves some parts sharp and others soft. Look at where the blur sits to identify the cause, then fix it with a faster shutter speed or better support for shake, and with different autofocus settings or technique for missed focus. Telling the two apart saves a lot of guesswork.
How to Tell Them Apart
| Clue | Camera Shake | Missed Focus |
|---|---|---|
| Where the blur is | Everywhere in the frame | Only in some areas |
| What it looks like | Streaks, ghosting or double edges | Soft but even, like a fog over detail |
| Sharp area | Often none | Something nearer or farther is sharp |
| Typical cause | Slow shutter, shaky hands, long lens | Wrong focus point, shallow depth of field, low light |
Zoom in to 100 percent and check the edges. If one object clearly looks sharp, then the camera hit focus somewhere, just not where you wanted.
Fixing Camera Shake
- Raise the shutter speed. A common rule of thumb is a speed of at least one over the focal length, such as 1/200 with a 200 millimeter lens. Go faster for high resolution cameras.
- Use stabilization. Turn on in-lens or in-body stabilization if available, and turn it off when the camera is on a tripod unless the manual says otherwise.
- Improve your grip. Hold the camera close to your body, keep elbows in and gently squeeze the shutter button.
- Use a support. A tripod, a wall or a bag of rice can steady the camera for slow shutters.
- Use a timer or remote. A two second delay prevents the shake caused by pressing the button.
- Raise the ISO. Higher sensitivity allows faster shutter speeds when light is limited.
Fixing Missed Focus
- Choose the focus point yourself. Use a single small point and place it on the key detail, such as an eye.
- Pick the right autofocus mode. Use single shot mode for still subjects and continuous mode for moving ones.
- Use subject or eye detection. Many modern cameras can track faces, eyes and animals.
- Widen the depth of field. Close the aperture a little, for example from f/1.8 toward f/4, when a subject moves slightly.
- Add light. Autofocus struggles in dim scenes. Add light or focus on a high contrast edge.
- Keep a minimum distance. Every lens has a closest focus distance, and moving back may fix the problem.
- Check your lens. If every shot focuses in front of or behind the subject, look for a focus adjustment option in your camera menu.
These settings are general guidance, so adjust them for your camera and subject.
FAQ
Can I fix a blurry photo in editing?
Sharpening tools can improve mild softness, but they cannot recover detail that was never captured. Fixing the cause in camera gives far better results.
What if the subject moved?
That is called motion blur. It looks like shake but only affects the moving subject. Use a faster shutter speed to freeze it.
The Short Version
If everything is blurred, steady the camera and raise the shutter speed. If only part is soft, adjust the focus point, mode or aperture, and add light when you can.
