This was a result of somewhat involved setup. The background is a photograph of a translucent plate with wavy pattern, placed on a clear glass. About a foot below is a light table with several pieces of colored gels on top. It was composited with a photo of my glass fish earrings. Canon EOS40D, Canon 60mm Macro lens at 60mm, 1/45 sec, f/6.7, ISO 200.
