Bokeh, in it's most technical definition, is the shape produced by taking an out of focus picture of a single point of light. The overlapping bokeh from all the myriad points of light that make up a scene creates the blur in out-of-focus areas.

People may have different preferences, but there are really just a few different measurable qualities of bokeh.

• What fundamental shape does it have? Hexagonal? Heptagonal? Are the edges flat or rounded? (this shape is produced by the aperture's blades.)
• Are the edges sharp or blurry?
• Is the disk of uniform brightness, or is it brighter in the center, or on the edges?
