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”. Definition taken from Wikipedia
I love using depth of field. This example was taken at Stourhead Gardens – a fantastic place to capture the colours if Autumn.
