What is Bokeh and How It Affects Your Images

Many photographers want beautiful, creamy bokeh in their photographs

Bokeh, also known as “Boke” is one of the most popular subjects in photography. The reason why it is so popular, is because Bokeh makes photographs visually appealing, forcing us to focus our attention on a particular area of the image. The word comes from Japanese language, which literally translates as “blur”.

What is Bokeh?

Basically, bokeh is the quality of out-of-focus or “blurry” parts of the image rendered by a camera lens – it is NOT the blur itself or the amount of blur in the foreground or the background of a subject. The blur that you are so used to seeing in photography that separates a subject from the background is the result of shallow “depth of field” and is generally simply called “background blur”. The quality and feel of the background/foreground blur and reflected points of light, however, is what photographers call Bokeh. Confused yet? Take a look at the following image:

House Sparrow
NIKON D80 @ 102mm, ISO 100, 1/100, f/2.8

The house sparrow is in focus and sharp (which means that it is inside the depth of field), while the background is out of focus (which means that the background is outside the depth of field). The small or “shallow” depth of field is the result of standing relatively close to the subject, while using a large aperture. See those round circles of different colors on the left side of the image? Those are light reflections and they are circular because that’s how the lens rendered them. In this case, the soft “feel” of those circular areas is what photographers would call “good bokeh”. While some photographers argue that bokeh is just about the quality of the circular light reflections, many others, including myself, believe that bokeh is about the quality of the entire out-of-focus area, not just reflections and highlights…

Good and Bad Bokeh

Remember, bokeh is rendered by the lens, not the camera. Different lenses render bokeh differently due to unique optical designs. Generally, portrait and telephoto lenses with large maximum apertures yield more pleasant-looking bokeh than cheaper consumer zoom lenses. For example, the Nikon 85mm f/1.4D lens produces exceptionally good-looking bokeh, while the Nikon 18-135mm f/3.5-5.6G DX lens produces poor bokeh at the same focal length and aperture – all due to differences in optical designs of both lenses. Again, I am not just talking about the background blur; all lenses are capable of producing out of focus blur, but not all lenses are capable of rendering beautiful bokeh.

So, what is a good or beautiful bokeh? A good bokeh pleases our eyes and our perception of the image and therefore, the background blur should appear soft and “creamy”, with smooth round circles of light and no hard edges. Here is an example of beautiful bokeh rendered by the Nikon 85mm f/1.4D lens:

Creamy Bokeh
NIKON D700 @ 85mm, ISO 250, 1/200, f/2.8

Pay attention to the smooth background behind the child’s face. The out-of-focus areas look creamy and the circles are round and soft with beautiful transitions between the blurry areas. That’s exactly what you would call good bokeh!

How about bad or ugly bokeh? Although a lot of people argue that there is no such thing as a bad bokeh, I still call whatever distracts my eyes “bad”:

Bad Bokeh
NIKON D80 @ 26mm, ISO 100, 1/60, f/4.0

Open up the larger version of the above image and see for yourself – the quality of the blur is not pleasant to the eye, with sharp edges of the circles and double lines.

Bokeh Shapes

The shape of the reflected light in out of focus areas depends on the lens diaphragm. Many older lenses such as Nikon 50mm f/1.4D have 7 straight blades in their diaphragms, which results in heptagon-shaped bokeh like this:

Bokeh - 50mm

Most new lenses, now come with 9 rounded blades, which render round bokeh (Nikon 105mm f/2.8G VR):

Bokeh - 105mm

How to Get Good Bokeh

So, how do you get a good bokeh in your images? As I have pointed out above, bokeh depends on the type of lens you are using. While lower-end consumer zoom lenses will yield unpleasant bokeh, fixed (prime) lenses and most professional zoom lenses with fast apertures yield good-looking bokeh.

Do you know if your lens produces good bokeh? Try this: focus on an object from a very close distance (as close as the lens will allow, keeping the object in focus), making sure that there are no objects at least 5-6 feet behind it. Make sure to be on the same level as the object itself, so that you are not looking down on it. Do not use a plain wall as your background – try to find a colorful background, preferably with some lights on it. A Christmas tree is a perfect background for a bokeh test.

Once you find a good test subject with a suitable background, set your camera to “Aperture Priority” mode and set your aperture to the lowest number. On most consumer zoom lenses, the lowest aperture is typically f/3.5, while on prime and professional zoom lenses, it can be between f/1.2 and f/2.8. Once the aperture is set to the lowest value, take a picture of your subject and take a look at the rear LCD of your camera. The subject should be in focus, while the background is blurred. If you have a good lens, the bokeh should be soft and fuzzy, looking pleasing to the eye as shown in the example above. The circular reflections should be round and soft, with no hard edges.

What Lenses Create Great Bokeh?

There are many lenses that create great-looking bokeh. Most fast prime lenses with round-blade apertures such as Nikon 85mm f/1.4G or Canon 85mm f/1.2 II USM create exceptionally good-looking bokeh. The lower-cost version of the same lens – Nikon 85mm f/1.8G and Canon 85mm f/1.8 USM also produce beautiful bokeh. There are too many lenses to list, so I recommend doing some more research on different lenses, based on your photography needs.

Other Examples of Bokeh

Here are some other examples of great-looking bokeh:

Curious if you can recommend techniques for “good” bokeh whennusing a non-professional lens.

Very helpful article. I do mainly extreme close-up photography so bokeh is very important to me. I love to shoot common subjects in a way that the viewer has never seen it before. Many of my best photographs are when the viewer has to ask “what is that” and when I tell them they are totally surprised.

Good article thank you!
I am just about to start learning. I have bought a Panasonic Lumix G9 with a 12-60mmm Leica lens and I have also a 25mm f1.7 prime lens with the package. I am reading lots before I attempt to start taking any photos. Hopefully this kit will allow me to get some good and interesting shots. I really wanted it to shoot 4k video for web content etc, but the photography side is a mine field with a large learning curve, however articles like this which break things down in to lamen’s terms are very helpful, so thanks again.
Regards Bobby

Hello Nasim,
I’m very interested in bokeh. I have a Sony A7III with a Sony 50mm f1.8, a Sony FE 85mm f1.8
and a Sony 28-70mm F3.5-5.6 FE OSS Interchangeable Standard Zoom Kit Lens. Are any of these capable of shooting bokeh images?

It would be easiest to get images with lovely bokeh using the 85mm f/1.8. Compose your image so that the background is very far away, and focus on something or someone relatively close by, such as a portrait of a human 8 feet away. Experiment with different backgrounds to see which best suits your taste.

Hi, so good bokeh is mix of sharp and not sharp, so both should be separate, for best bokeh, the more sharp at center, the more blur at outward, the better the blur, the better your focus to center, which you say bad bokeh is distracting you. So, what do good and bad bokeh depend on what? It is ratio of F, and so on? The more you absorbs the light, the more it reflects outward from your eye to result of an imagine, so that imagine is sharp. So, outward as the light spread out, same as sun itself, the further you are from the sun, the lower heat you feel, the lower intensity you see from the sun, and the smaller the sun you see, so the blurry increase. So, it doesn’t depend only by ratio of F, but also depend by iso, how much light you increase that interact external light with internal light that is iso? There is light in camera that increase or decrease, to cause good bokeh or bad bokeh. It is about balance of ratio of two light to cause good or bad bokeh? So, camera is about knowing how good the zoom, and how good is ratio of contrast of two, the most sharp to the most blur, which the center that absorbs your attention is details, and the most blur outward is lowest details, so the details itself expand, so like two light that overlap, so it blurs, so the more it overlaps, the more the blur, the more lowest details and the more opaque, not transparent. It is ratio of opaque to transparent. Zoom depend on F, good blur depend on what? ISO? Or combine of both?? So, two things is important for camera is zoom and good bokeh, when you have good bokeh, the center will be the most details and you can see more, right. So, it is connect to resolve. So, bokeh is result of imagine that connect to resolve, the process. It depends on light itself and combine of two light, external and internal. So, it is not just external light, but external and internal light that blend well?

I recently found a used Tokina 500mm f8 mirror lens and after some fiddling with my Pentax K5 to make them work together, it’s a marvelous lens for producing bokeh. Very smooth indeed! Doing floral or such reveals a buttery background which really works for me.

Hi there! So I recently bought a Fujifilm x-A5 with 15-45mm and f3.5-5.6. They say that it’s good for beginners. I wonder how I can maximize it’s use given its lens and aperture spans. Thank you!

Hello
I own a d3300 with kit lens as well as 55-200 from Nikkon. I’m an aspiring photographer, love doing landscapes but would love to start portrait (studio) photography. I really care about a good bokeh and bright pictures. I just bought a Nikon 50mm 1.8 G. Can you advise me what other lenses I can get that will produce best results with my D3300, before I have a chance to go pro with a FX camera ? Best lenses for indoor and outdoor people photography that will have professional quality to the images since I’m looking to get into paid photography.
Thank you!
