How to Master the Bokeh Effect: Settings, Lenses and 8 Films

What is the bokeh effect? It is the look of the out-of-focus parts of a shot: the soft blur behind a sharp subject, and the glowing discs that small lights turn into. Bokeh is not the blur itself. It is the quality of that blur, and two lenses at the same setting can give you very different bokeh.

This guide covers what bokeh means, how it differs from depth of field, what shapes it, the settings and lenses that create it, and how it changes when the camera is rolling instead of clicking. Then come 8 films that use the bokeh effect to tell their story, ranked by how much the blur carries the meaning of the scene, not by how pretty it is. For the bigger picture, see our cinematography guide for beginners.

What Does Bokeh Mean?

Bokeh comes from the Japanese word boke, which means blur or haze. Photographers in Japan talk about boke-aji, the “flavor” of the blur.

The word reached English in 1997, when Mike Johnston, then editor of Photo Techniques magazine, ran three articles on it. He added the “h” so English speakers would say it right. Say it “BOH-keh” or “BOH-kay”. Both are accepted.

Is bokeh good or bad? Neither. Smooth, even blur is called good bokeh. Busy, nervous blur with hard-edged rings is called bad bokeh. Plenty of filmmakers choose the “bad” kind on purpose, as you will see below.

Bokeh vs Blur vs Shallow Depth of Field

Depth of field is how much of the shot is sharp. Blur is anything outside it. Bokeh is what that blur looks like.

	What it means	What controls it
Depth of field	The zone from near to far that looks sharp	Aperture, focal length, distance to subject
Blur	Anything outside that zone	The same three, plus motion
Bokeh	The look and feel of the out-of-focus areas	The lens design: blades, glass and shape

A shallow depth of field gives you more blur to look at, which is why bokeh and shallow focus go together. Our guide to aperture and depth of field explains the sharp part in full. This page is about the soft part.

What Shapes Bokeh?

The lens shapes the bokeh. Change the glass and the same background looks completely different.

• Aperture blades. Wide open, small lights become round discs. Stop down and they take the shape of the blades: hexagons, heptagons, octagons. More curved blades keep the discs round.
• Anamorphic lenses. These squeeze the image sideways, so bokeh comes out as tall ovals. It is one of the quickest ways to make footage read as cinema. Searchers call it anamorphic bokeh or oval bokeh.
• Cat’s eye bokeh. Near the edges of the frame, the lens barrel clips the discs into lemon shapes that point toward the center.
• Swirly bokeh. Old lenses like the Helios 44, a 1958 Soviet copy of the Zeiss Biotar 58mm f/2, and Petzval portrait lenses swirl the background around the subject. It is strongest wide open.
• Bokeh balls and onion rings. Bright points of light make the clearest bokeh balls. Lenses with aspherical elements can add faint rings inside each disc.

How to Get the Bokeh Effect

To get the bokeh effect, you need a shallow depth of field and something interesting behind your subject. Five moves do it:

1. Open the aperture. f/1.4 to f/2.8 is the usual range. Is f/2.8 enough for bokeh? Yes, with a longer lens and a distant background.
2. Use a longer lens. An 85mm at f/2.8 blurs the background more than a 24mm at f/2.8.
3. Get close to your subject. The nearer the focus point, the shallower the focus.
4. Push the background away. Put 10 feet or more between your subject and what is behind them.
5. Put small lights in the background. Fairy lights, streetlights, windows or sun through leaves. The blue hour gives you city lights and enough sky to see your subject.

Bokeh in Video vs Photography

Bokeh photography is easy in daylight. Open the lens and raise the shutter speed to 1/4000. Video cannot do that. Filmmakers keep the shutter near 180 degrees, about 1/50 at 24 frames per second, so motion looks natural. Our guide to the 180 degree rule explains that second rule with the same name.

With the shutter fixed, too much light comes through a wide-open lens. The answer is an ND filter, which works like sunglasses for the lens. It is the one piece of kit that separates bokeh on video from bokeh on stills. Our guide to the exposure triangle shows how the three settings balance.

The other catch is focus. At f/1.4 the sharp zone can be a few inches deep. If your actor leans forward, they fall out of it. On a film set, the first assistant camera pulls focus by hand on every take. On your own shoot, rehearse the move and mark the floor.

Best Lenses for Bokeh on a Budget

You do not need an expensive lens for good bokeh. You need a fast one.

• A 50mm f/1.8. The cheapest fast prime most camera makers sell. Every beginner should own one.
• An 85mm f/1.8. The classic portrait length. It flattens faces kindly and melts the background.
• Old manual primes on an adapter. A Helios 44-2 is the usual first buy for swirly bokeh. Manual focus rings are long and smooth, which suits video.
• Anamorphic lenses and adapters. The route to oval bokeh and horizontal flares. Adapters are cheaper but fiddly, and real anamorphic primes cost more.

Light matters as much as glass. A wide-open lens needs something to blur, so build your background with practical lights, as our guide to lighting in film shows, or shoot at golden hour with natural light behind your subject.

8 Films That Use Bokeh to Tell the Story

These 8 films count down to a Holocaust drama that uses shallow focus as its whole method. Each one is ranked by how much the blur carries the meaning of the scene. Two of them are animated, which proves bokeh is a choice, not an accident of the lens.

8) Spider-Man: Into the Spider-Verse (2018)

Into the Spider-Verse threw out the lens blur and replaced it with a misprinted comic book.

VFX supervisor Danny Dimian told fxguide the team noticed that misaligned color plates in old comic books “looked like the image was out of focus.” So instead of soft blur, the background of a shot splinters into offset reds and blues, like a page printed slightly off.

The team threw out motion blur too, using drawn lines instead. The result is a film where the out-of-focus world still looks hand-made. Read more in fxguide’s breakdown of the film.

7) Toy Story 4 (2019)

Toy Story 4 built virtual copies of real anamorphic lenses so plastic toys could have oval bokeh.

Pixar does not need a lens at all. Lin modeled his virtual lenses on Cooke’s anamorphics anyway, complete with oval bokeh, horizontal flares and shallow focus, as he explained to No Film School.

Even in a world built entirely from code, the backgrounds fall into the soft ovals a live-action camera would give you. That tells you audiences read bokeh as “cinema”, even when they cannot say why.

6) Poor Things (2023)

Poor Things used old Petzval lenses to swirl the world around Bella.

Petzval lenses date from the 1840s. They are sharp in the middle and swirl toward the edges. Ryan had rehoused versions built for the film. “The rehoused Petzval gives you this lovely bokeh,” he told Y.M.Cinema.

Paired with fisheye-wide lenses and Ektachrome film, the swirl makes Bella’s world feel slightly unreal, as if seen by someone discovering it for the first time. It is the strongest argument for swirly bokeh in a modern film.

5) The Social Network (2010)

The Social Network made real rowers look like toys by blurring everything around them.

The Henley Royal Regatta sequence is the only action scene in the film. The Winklevoss twins race while the world around them goes soft at the top and bottom of the frame, the tilt-shift look that makes real places look like model railways.

According to AWN, a52 built that narrow focus in post because “everything around them is literally out of focus.” The twins are losing a race and losing the story, and the blur makes them look small.

4) Carol (2015)

Carol shoots through rain, dirty glass and fogged windows until the city melts behind its two women.

Lachman shot Super 16 to recall the Ektachrome photographs of the 1950s, and chose Speed Panchros on day exteriors because he liked their fall-off at the edges. He used no diffusion filters at all.

“Shooting through glass, with reflections and the weather, created its own kind of diffusion,” he told Film and Digital Times. Therese watching the city through a wet taxi window, with every light smeared into soft color, is the image people remember.

3) The Diving Bell and the Butterfly (2007)

The Diving Bell and the Butterfly uses blur to show what a paralyzed man can see.

Jean-Dominique Bauby wakes from a stroke able to move only his left eyelid. For the first part of the film, we see only what he sees: faces sliding out of focus, frames tipped at an angle, a world he cannot turn his head to fix.

Kamiński used an ARRI shift and tilt lens system to throw parts of the image out of focus. “If these tools had not existed, I would have come up with some other way of putting the image partially out of focus,” he told MovieMaker. Here bokeh is not decoration. It is a disability, felt from the inside.

2) The Assassination of Jesse James by the Coward Robert Ford (2007)

The Assassination of Jesse James blurs the edges of the frame like a photograph from the 1880s.

The first Deakinizer was a wide Kinoptik lens with one element taken out. Later versions put single elements on ARRI macro lenses with swing-tilt mounts or bellows. Deakins built them with Otto Nemenz, as the ASC’s Shot Craft series explains.

He used them “typically for transitions” and in the opening, while the narrator tells the life of Jesse James. The center stays sharp, the edges smear, and the film feels like it is being remembered rather than watched.

1) Son of Saul (2015)

Son of Saul keeps one man in focus and leaves the horror of Auschwitz as bokeh around him.

Saul works in a Sonderkommando unit in the camp. The camera stays a few feet from his face for almost the whole film, and the 40mm lens keeps the background soft. What happens behind him is there, half seen and heard, never on display.

“The concept was to limit the amount of information reaching the audience while still giving them the story,” Erdély told British Cinematographer. The film won the Oscar for Best Foreign Language Film and the Grand Prix at Cannes. It is the clearest case on this list of blur doing the storytelling.

Bokeh on iPhone and Android

Phones fake the bokeh effect. Portrait mode and Cinematic mode build a depth map of the scene, then blur the background in software. It works best on people with clean edges, and it struggles with hair, glasses and fast movement. Our guide to iPhone Cinematic mode shows how to get the most out of it.

FAQs About the Bokeh Effect

The Final Cut on the Bokeh Effect

The bokeh effect is the quality of the blur, not the amount of it. Open the aperture, use a longer lens, get close and push the background away, and the lens decides the rest: round discs, ovals, swirls or smeared edges.

Here is a drill for this week. Put one subject in front of a string of lights. Shoot the same framing at f/1.8, f/4 and f/8, then compare. You will learn more about bokeh from those three shots than from any lens review.

When you are ready to go deeper, read what a cinematographer does with these choices on set, and how shot composition decides what stays sharp.
