Web Diffraction with Spider

The spider seems to be suspended from colourful ropes, but of course it is just the out of focus diffraction patterns from the main threads. Having the dark background makes the colours more obvious.

With a macro lens and large aperture the small depth of field means only part of the web can be in focus.

With the sun at a suitable angle moving out of focus can produce some interesting effects.
