How Can I Blur My DSLR?

Q: Can I add blur after I’ve taken the shot?

Yes—Snapseed or Photoshop Express can fake it. Load the photo into Snapseed (Android or iOS) or Adobe Photoshop Express . Tap Tools → Selective . Paint a tiny circle over the subject, bump up the Brush Size , then crank Blur to 100. Paint over the background, tap the checkmark, and export.

Q: I still see the background—why?

Add more distance between subject and background. Step back another 3–6 ft or bring the subject closer to you; every extra foot knocks the background blur up roughly 30 % Photography Life .

Quick Fix Summary

Fire up your camera app, switch to Portrait mode, then tap the shutter. No Portrait mode? Dial in the widest aperture (lowest f-number) and put some space between your subject and whatever’s behind them. Can’t get it in-camera? Slap the shot into Snapseed or Photoshop Express and add the blur later.

What's Happening

You’re creating a shallow depth of field.

That buttery background blur you’re after—called “bokeh” by people who sound smarter than the rest of us—happens when only a thin slice of the scene stays sharp. Cameras pull this off either automatically in Portrait mode or by letting you pick a fast lens and a wide aperture (that’s the low f-number).

How do I do it on a smartphone?

Open your default camera, find Portrait mode, and shoot.

Fire up the built-in camera app.
Swipe or scroll until you spot Portrait mode—usually a little person icon inside a circle.
Keep your subject about 2–8 ft away from the background.
Frame the shot until the yellow depth-peeking box hugs the subject.
Tap the shutter; the camera handles the rest.

What about DSLRs and mirrorless cameras?

Switch to Aperture Priority or Manual, open the lens as wide as it goes, and put distance between subject and background.

Spin the mode dial to A (Aperture Priority) or M (Manual).
Pop on a lens that opens to at least f/2.8; f/1.8–f/1.4 gives you noticeably creamier blur.
Keep ISO between 100–400 if you’re shooting in daylight.
Crank the aperture to the smallest number your lens allows—say, f/1.8.
Move the subject as far from the background as your space lets you; the farther the background, the silkier the blur.
Focus on the eyes and squeeze the shutter. Hit the viewfinder’s depth-of-field preview button to eyeball the blur before you commit.

Any tips to make bokeh look its best?

Location scouting, clean glass, and the right focal length matter.

Scope out the spot beforehand; plain walls or hedges need less blur drama. Wipe the front element—dust spots scream in soft highlights. Shooting a group? Grab an 85 mm or longer lens so everyone stays sharp while the foreground and background melt away. And if you want to tweak blur intensity later, shoot RAW—you’ll thank yourself when you’re editing.
