Sometimes that effect is desirable in certain images. The correction for spherical aberration will be inferior and that may cause a harder edge to the “Bokeh” discs which will appear harsher and more distracting in the background. The maximum Aperture opening is much smaller so the potential for a very shallow depth of field is reduced. The so-called bad “Bokeh” is produced by cheaper lenses with inferior optical design. Bokeh Is Not Always About Sharp Points Of Light In The Background The quality of the optical design is usually superior with these high-quality lenses and therefore the correction for spherical aberration will leave the “Bokeh” discs with a soft, smooth edge. ![]() This smooth rendition of soft point-lights in the background, the good “Bokeh” are usually produced with prime lenses or zoom/telephoto lenses with very large maximum apertures like f2.4 or f2.8. They also have a nearly perfectly circular shape. This is a subjective matter but the good “Bokeh” is thought to appear soft and smooth, blend well together in the background and generally have a pleasing effect while not distracting from the sharply focused subject. Abstract Cityscape Defined By Fully-Open-Aperture Bokeh Discs – Photo by Oscar J Harper Good And Bad Bokeh These are produced because points of light in the blurred areas become an image of the Aperture opening, whatever shape it happens to be. This is the most iconic rendition of “Bokeh” that we all know but what creates these floating globes of light? Sometimes they are perfectly circular and other times they are polygonal. They are often produced in the out-of-focus regions of an image by Christmas tree lights or a distant city street or a cityscape far off in the background. When we think about “Bokeh”, most of us have visions of those magical, floating discs of myriad lights produced by blurring hundreds of tiny points of light in the background. Illustrated Guide to Bokeh in Photography Discs of Light Keep reading for an illustrated guide on “bokeh” in photography and how to reveal it. It is often associated with the results of how the lens presents out-of-focus points of light in the blurred areas but it also describes the quality of all out-of-focus areas in a photograph. You have to understand the principles of depth-of-field and Aperture opening size. There are various ways to achieve a degree of “bokeh” in your photographs and the effect varies with different types of lens and different focal lengths. Cityscape Silhouette – Bokeh Discs From Points Of Lights – Photo by Oscar J Harper The effect is enhanced when points of light are present in the blurred areas. The current spelling “Bokeh” was popularized in 1997 when Mike Johnston, the editor, changed the spelling in “Photo Techniques” magazine after commissioning articles on the subject.īokeh in photography is the aesthetic quality of the areas of an image that fall outside of the sharp depth-of-field of a lens using a large aperture opening it’s the out-of-focus regions in the background or foreground. The description of the quality of the blur in a photo has now found its own buzzword “Bokeh” which means “blur” or “Haze” in Japanese! Pronounced with two syllables, “Bo-Keh” it is derived from the Japanese phrase “Boke-aji” which refers to “blur-quality”. The out-of-focus background can have varying degrees of blur and varying degrees of quality. ![]() A blurred background can lift the main subject out of the chaos of the scene and make them stand out and look sharper.
