Victoria harbour bokeh
In photography, bokeh (Originally  /ˈboʊkɛ/ /ˈboʊkeɪ/ boh-kay, and also sometimes heard as  /ˈboʊkə/ boh-kə,Japanese: [boke]) is the blur,or the aesthetic quality of the blur,in out-of-focus areas of an image. Sometimes bokeh is misleadingly defined as &quot;the way the lens renders out-of-focus points of light.&quot;since it is the characteristic of the image, not the lens itself. However, 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—&quot;good&quot; and &quot;bad&quot; 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.[3] However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.
