Diffraction Star Photos

by rb780nm on May 20, 2014

I was flicking through a photography book while hanging out in Brisbane airport on Sunday night, looking at ‘creative’ photo ideas. I didn’t have much of my camera gear with me – just the one lens and a little tripod… but I found a section on diffraction star effects – photographing the diffraction patterns caused by the edges of the lens aperture.

So I took this series a photos with gradual steps in aperture size.

As the aperture opens up, the diffraction effect becomes smaller. It also rotates slightly as the positions of the blades of the aperture move…
