In photography, bokeh (pronounced /boʊˈkeɪ/) 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” and “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. – Wiki
That’s actually a perfect description. In the above photo, I have chosen to to apply this ‘bokeh’ effect while I was out in the field to the background of the image. This effect was pretty simple to do and really makes the subject in the photograph pop out. To put it simply, the ‘bokeh’ is the blurry background.
Hope you enjoy!
