Paraphrased from Wikipedia
Bokeh
In photography, bokeh is the blur, or the aesthetic quality of the blur,
in out-of-focus areas of an image, or "the way the lens renders
out-of-focus points of light." Differences in lens aberrations and
aperture shape cause some lens designs to blur the image in a way that is
pleasing to the eye, while others produce blurring that is unpleasant or
distracting? "good" or "bad" bokeh, respectively. Bokeh occurs for parts
of the scene that lie outside the depth of field. Photographers sometimes
deliberately use a shallow focus technique to create images with prominent
out-of-focus regions.
Bokeh is often most visible around small background highlights, such as
specular reflections and light sources, which is why it is often
associated with such areas.[ However, bokeh is not limited to highlights,
as blur occurs in all out-of-focus regions of the image.
The term comes from the Japanese word boke, which means "blur" or "haze",
or boke-aji, the "blur quality". The Japanese term boke is also used in
the sense of a mental haze or senility.
