Polarised CD

When I have been experimenting with polarisation using the back of CDs previously I have usually focussed in on one of the lights patterns so you are unaware of the background. Tonight I concentrated on getting an attractive polarisation right across the surface of the CD so that I could chow you the whole of the CD. The patterns change with any slight movement of the camera and I was hand holding so I had to boost my chance of success by choosing the smallest possible aperture (f32) and racking up the ISO to effectively freeze the subject. If you fancy experimenting all you need is a torch and the back of any old CD.
