... a photographers dream isn't?
According to Wikipedia:
"In photography, bokeh is the blur,[1][2] or the aesthetic quality of the blur,[3][4][5] in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."[6] 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.[1] 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.[1] However, bokeh is not limited to highlights, as blur occurs in all out-of-focus regions of the image."
Yeah, that nice smooth blur of color or texture, sometimes makes for perfect portraits.
Lately I've been dressing up my bokeh with color or lights. Today's image was shot at the office. Low lighting so D-80 ISO500 and kit lens again.
I just put a bunch of colorful things on the cabinet and placed the Willow Tree Angel about a foot in front of the "stuff."

I think the colorful "stuff" adds interest to an otherwise white wall.
