Shallow depth of field can also create an interesting affect, particularly with bright areas, such as raindrops, reflections on water and streetlights. These are called ‘circles of confusion‘. The shape or aesthetic quality of these circles is called Boke or Bokeh (pronounced Bow-ca), a phrase that has become popular in recent years on social media and online forums.
