"To get great bokeh, you not only need a wide aperture, but you also need to get close to your subject. This will really separate the subject from the background."

Another work of "Bokeh" photograph on potraiture.

This photograph was taken on an evening with telephoto lens 55-250mm to get close to the subject.  This is another way to get bokeh effect besides using the wide open apperture.
