An English transliteration of a Japanese word that means haze or blur. Pronounced boh-keh, it refers to the out-of-focus areas in a photograph with limited depth of field, particularly around, but not limited to, the highlight areas. Bokeh appears as little circles in the unsharp areas. Depending upon the shape of the opening formed by the blades of the lens’s aperture, the circles appear either more or less circular.

Bokeh is the English form of the Japanese word boke, which means blur. It refers to how out-of-focus parts of a photo look. Different lenses produce different-looking out-of-focus backgrounds, depending on things like the number and shape of their aperture blades. In general it could be said that the softer the out-of-focus elements look, the more pleasing the bokeh.
(sometimes spelled boke) - refers to the blur, or more specifically, the quality of the blur in out-of-focus areas of a photograph. There is no firm definition for what is good or bad bokeh, since its degree of quality is in the eyes of the beholder. However it seems to be generally accepted that softer, smoother edges for blurred areas are preferred.
often mispronounced “bow-kay” or “bow-kuh” it is correctly pronounced as “bo-ke” like the ke in kettle. It is used to described the out of focus blurred bits in the background when “fast glass” is used. Most often bokeh occurs where small light sources are in the background, far in the distance.
