Bokeh

The term 'Bokeh' comes from the Japanese word meaning 'fuzziness or dizziness', which completely sums up what Bokeh is,  'out-of-focus' points of light.
Bokeh is different from sharpness, sharpness is what happens at point of best focus, Bokeh is what happens away from the best point of focus. Blurred, out of focus, fuzzy and creative images.

Differing amounts of spherical aberration, alter how lenses render out-of-focus points of light, and then there is Bokeh. Enjoy
