Bokeh is out-of-focus areas in a photo. Bokeh is determined by the way how the lens renders unsharp points of light. It's often used for creating artistic effects - to blur backgrounds for visual selection of a main object in a scene. In photography, bokeh effect depends on the shape of the aperture. Various shapes let you achieve artistic background blur effects, for example with stars.
With the program AKVIS Refocus you can make a variety of figure bokeh on any photo.
