The exposure for this picture was 84 seconds. The orb was created using multi-coloured LED lights. These are spun around a central point. If you look closely underneath the orb, you can just see the CD disc used for this purpose. I draw a cross on this disc and use it as a guide to start and spinning the orb. I find the process very therapeutic and it can be really rewarding seeing the finished image on the rear screen of the camera.
