Bokeh Filters.

Bokeh is the aesthetic quality of the blur produced in the out of focus area of a photograph. It is more prominent when using prime lenses at lower depth of field, such as f/1.2. Many years ago I discovered a fun technique for changing the shape of the Bokeh using homemade filters. Using a black piece of card cut out in a circular shape to slot into the front of the lens and then removing a small piece from the centre in your desired shape i.e. a star or heart, you can then change the shape of the aperture ring and see shaped Bokeh blur. This only works with a prime lens and the larger the aperture the better, for example f1.2-f1.8. It will work best when either out of focus or on backgrounds with natural light sources, such as dappled light through plants or Christmas lights.
