Light Bokeh

In photography, bokeh (/ˈboʊkə/ BOH-kə or /ˈboʊkeɪ/ BOH-kay; Japanese: [boke]) is the aesthetic quality of the blur produced in out-of-focus parts of an image. Bokeh has also been defined as "the way the lens renders out-of-focus points of light".[5] Differences in lens aberrations and aperture shape cause very different bokeh effects.[6] Some lens designs blur the image in a way that is pleasing to the eye, while others produce distracting or unpleasant blurring ("good" and "bad" bokeh, respectively).[6] Photographers may deliberately use a shallow focus technique to create images with prominent out-of-focus regions, accentuating their lens's bokeh.

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.[6] However, bokeh is not limited to highlights; blur occurs in all regions of an image which are outside the depth of field. https://en.m.wikipedia.org/wiki/Point_source#Light https://en.m.wikipedia.org/wiki/Specular_reflection https://en.m.wikipedia.org/wiki/List_of_light_sources https://en.m.wikipedia.org/wiki/Bokeh#cite_note-davis-6 https://en.m.wikipedia.org/wiki/Depth_of_field Pics by me
