Tutorial #1 Bokeh Shapes: Introduction

For those who may not know, the blurry/out-of-focus area in an image is called Bokeh. It's derived from Japanese "bo-ke" meaning blur or haze. Changing the shape of the aperture on a lens will change the shape taken by the out of focus elements in the image.

 

The photo above was shot with a Sigma 50mm f/1.4 - which has an aperture containing 9 diaphragm blades. The greater the curvature and number of blades that make up an aperture the rounder and smoother the bokeh will appear. Lenses with less aperture blades will have different polygonal shapes - depending on the number of blades. Due to this property, changing the shape of the aperture changes the shape of the out of focus elements...which leads us to this tutorial...

 

In this tutorial, you will learn how to create cheap do-it-yourself bokeh shapes. There are all sorts of kits out there you can BUY...but this method is something you can do with stuff you just have lying around waiting to be used...like your digital SLR and your economically priced 50mm lenses...
