/ˈboʊkə/ boh-kə,[1] Japanese: [boke]) is the blur,[2][3] or the aesthetic quality of the blur,[4][5][6] in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."[7] Differences in lens aberrations and aperture shape cause some lensdesigns to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively.[2] Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions. The term comes from the Japanese word boke (暈け or ボケ), which means "blur" or "haze", or boke-aji (ボケ味), the "blur quality". The Japanese term boke is also used in the sense of a mental haze or senility.[8] The term bokashi (暈かし) is related, meaning intentional blurring or gradation. From Wikipedia, the free encyclopedia.
