Colours and patterns arising naturally from the interference of reflected light rays from the front and rear surface of a thin film of water and soap held in a tiny frame (a 'bubble wand'). The inner circle which I use for these photos measures 18mm. Some of the shots are of tiny areas within that ring.

Sony Alpha 100 SDLR camera with Cosina Macro 100mm lens until 2013 then Nikon D600 with Nikkor 105mm macro lens
