>>3070409For you, from wikipedia: Bokeh "[...] is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens."
Just because you think this means there have to be balls of light in your background, this doesn't have to be correct.
You know it depends on your focal length, aperture, proximity to the subject and distance of the subject to the background?
Here's another shot at f/2.8 with the same lens, just different conditions.
