In photography, bokeh is the blur or the aesthetic quality of the blur in out-of-focus areas of an image. The term comes from the Japanese word boke, which means “blur” or “haze.” 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. In simple terms, the goal is for the subject to stand out.
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. This type of photography is very interesting, and can make even the simplest objects look spontaneous and beautiful. For your inspiration, here are some of top notch photographs showcasing this style of photography.
