After initial experiments with a flat white surface produced subpar results, Faye Berber settled on the dimpled metal case (A) from a Prima knife set. She positioned a 22-inch reflector disc (B) opposite her camera, a Canon EOS 40D with a 17–85mm f/4–5.6 Canon EF-S IS lens (C) mounted on a Velbon CX-586 tripod (D). Using a straw to blow bubbles with some Miracle Bubbles liquid soap (E), she experimented with two LED flashlights (F), aiming them at various angles until she was satisfied with the reflection pattern. The arrangement she settled on pointed each light almost directly at each other, but out of alignment and off axis to the camera enough to capture the reflections in the bubble while keeping the background dark. "First, the light hits the surface a little bit, and bounces back to the dome of the bubble," she says. "That's what creates the little rainbows."
