B for Bokeh
Japanese origin word for blur in the background of a photo. Used widely as an aesthetics tool in the photograph to give it a dreamy smooth out-of-focus background. With decrease of the Aperture number, the bokeh effect becomes more distinct and profound. The shapes formed in the bokeh of light sources, varies on the number of blades within the lens. Bokeh can be used creatively by use of filters to produce specific shapes in the photo.
