In photography, bokeh (originally /ˈboʊkɛ/, /ˈboʊkeɪ/ boh-kay — also sometimes pronounced as /ˈboʊkə/ boh-kə, Japanese: [boke]) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens.Bokeh has been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and apertureshape cause some lens designs 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.^[7] 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.
