Playing with Bokeh

Bokeh: the blur in the out-of-focus areas of an image produced by the lens. Each lens will produce a different ‘blur’ shape and it is to do with the shape of the shutter hole that that the light has to travel through, you will be able to see this most clearly in light sources such as christmas fairy lights and background street lighting at night.

By creating an additional hole for the light to travel through you can manipulate the light and create some beautiful imagery!

You can use any shape that you like too!
