Usage in photography īokeh is used in all kinds of photography, but it's most common in nature, portrait and sports photography, photographers find it useful as it can "isolate" the subject away from the background, making the subject the main part of the picture. Some camera lenses have a bokeh that looks like it "swirls" around the subject, often called swirly bokeh, it is used in portrait photography, and is caused by lens defects, though some special camera lenses are designed to have it.īokeh also takes on the shape of the aperture which the light passes through, making most bokeh circular in shape, which also means a lens "mask" made of black paper that has a certain shape cut into it can be placed over a camera lens to make the bokeh shape conform to that of the shape cut into the paper (for example, a love heart).Ĭatadioptric lenses (camera lenses and telescopes that use both mirrors and lenses) make a ring-shaped bokeh due to the presence of a mirror in the middle of the lens. While many people think only the focal length and the maximum aperture are important, there is actually much more to it, as I will try to show you in this article. The term "bokeh" is hardly used in optics, experts in the field refer to it as defocus, as bokeh is related to lens focus, meaning a picture completely made of bokeh is just an out-of-focus picture. The bokeh quality or a lens’ rendering for that matter is probably one of the most discussed and maybe also most important aspects of a (fast) lens. The quality of bokeh can be "good" or "bad", while it may vary due to different tastes, good bokeh is usually defined as being "smooth" as the background seems to "melt", whereas bad bokeh is usually defined as being "blobs" of light that make up the background. The picture at the bottom was taken with a very small aperture, whereas the picture at the top was taken with a big aperture.īokeh is not a special technique but rather a natural effect caused by what photographers (people who take pictures) call a narrow depth of field, it simply means that the more light a camera lens lets in, the more blurry the background can be, distance between the subject and lens also affects bokeh, if the subject is far enough away, there will be no bokeh.
