The quality of the blur has come to be known as “bokeh”. Bokeh in terms of photography referring the area in the photo which are out of focus light to increase beautiful and dramatic image. The origin of the term is from the Japanese word “romaji” (english characters) is spelled “boke” (pronounced bo-keh) and which means “fuzzy”. For good Bokeh, ideally points and lines would blur smoothly as they fell out of focus, in the manner, for example, of a smooth Gaussian blurring.
