To make this image, I placed the vase of tulips on a mirror, and lit the vase and flowers from behind with a standing light box. This is the same setup and technique I used in the images shown in HDR is technique, not style. You can see the setup and get an idea about the processing from the spread on pages 128-131 of Creating HDR Photos.

I also experimented with a simulated, virtual solarization of the image, converted to black & white, shown below.
