I can sing a rainbow

I will be amazed if anyone guesses what this colourful wotsit really is, so I'll tell you. It's the edge of a CD!

No way!! You find the most interesting things to photograph!

@stownsend It is. It surprised me. The edge looks so very deep, doesn't it and there are tiny indentations along the rim too.
Thank you, Suzie

I'd never have guessed that it was a CD, lovely capture

@bigmxx I had no idea what to expect but certainly not this!
Thanks very much

This turned out rather well I'd say. I never would have thought to photograph the edge of a CD. Nice capture of the rainbow of colors in this.

Lots to see close up.

@pej I wasn't trying to photograph the edge, Paul, rather the faint rings you can see if you hold a CD at the right angle. With the reversed lens, tolerance is zero so you don't always get what you want. Didn't expect this at all but quite like it.
Thank you

@joev You are right, Joe, a CD is just a plastic circle - but it obviously isn't!
Thank you
