The physical diffraction and light scattering effects on spider webs depend on many things, like incident light angle, thickness of the threads (and thus the spider species) and so on.

In addition, there comes the specific bokeh rendering of the lens used, which can lead to very surprising results. Im am showing only a few of many possible results here. BTW, the spider's name is "Emma", she is our new pet and lives on the balkony. She is really a very patient model :-)

Magnification approx. 2:1
