Bokeh is the quality of the out-of-focus areas in a photograph, especially how soft and pleasing the blur and highlights look. You get more of it by using a wide aperture, a longer focal length, a close subject and a distant background. These settings are general guidance, and you can adjust them to your scene.
What Bokeh Really Means
People often use the word to mean any blurry background, but strictly it describes the character of the blur. Smooth, creamy blur looks different from busy, nervous blur, even when both have the same amount of softness. Bright points of light in the background turn into soft discs, and their shape and edges are part of the look.
What Controls Background Blur
- Aperture: a lower f-number such as f/1.8 or f/2.8 opens the lens wider and makes blur stronger.
- Focal length: longer lenses such as 85mm or 135mm compress the scene and enlarge the background blur.
- Subject distance: the closer you are to the subject, the shallower the depth of field.
- Background distance: the farther the background sits behind the subject, the softer it becomes.
- Sensor size: larger sensors give more blur at the same framing and aperture.
Steps to Get Better Blur
- Choose your widest aperture, or one stop down if you want a bit more sharpness across the subject.
- Move to a longer focal length if your lens is a zoom.
- Place the subject at least a few steps from the background; several meters is better.
- Get close enough that the subject fills a good part of the frame.
- Focus carefully on the nearest eye or the key detail, since depth of field is thin.
- Look for backgrounds with leaves, lights or soft color rather than hard lines.
Shaping the Look of Highlights
The lens design affects the discs of light. More aperture blades usually give rounder discs when stopped down. Some lenses show an onion-ring pattern or cat’s-eye shapes near the frame edges, which is a trait of the optics and not a fault in your technique. Check sample photos from the lens you are considering to see whether you like the style.
| Goal | Suggested setting |
|---|---|
| Portrait with soft backdrop | 85mm at f/1.8 to f/2.8 |
| Detail shot with blur | Close focus at f/2.8 or wider |
| Phone or small sensor | Move closer, use portrait mode |
FAQ
Can I get bokeh with a kit lens?
Yes, to a degree. Zoom in, open the aperture as far as it goes, get close to your subject and keep the background far away. The effect will be gentler than with a fast prime.
Is more blur always better?
No. Extremely shallow depth of field can leave parts of the face or product out of focus. Pick the amount that suits the story of the photo.
The Short Version
Bokeh describes how the blurred parts of a photo look. For more of it, open the aperture, use a longer focal length, get close to the subject and separate it from the background.
