Bokeh

Pronounced "Boke-uh." Pertains to the amount of artistic blur produced from one's camera lens or created through a theoretical camera in a 3D scene. Bokeh refers to the Japanese word "Boke," or sometimes "Bokashi." As in most Japanese terminologies, there is good Bokeh, and bad Bokeh. It is commonly used for macro lenses to where there really is no focal definition and the subject is needed to be drawn out from the scene. The same applies with 3D art. The main different between the use of computer generated Bokeh and real lens Bokeh is that photographers usually come out with the clean result completely by accident. The direct definition of Bokeh is often not certain, as not much in Japan is, but it simply refers to the amount of background blur used to give the image definition. Anyone who attempts to explain the direct meaning as "How much blur," or "How little blur," there is in a scene, is wrong. It more directly applies to the quality of the blur. 3D programmers hate this effect.
