From my recent Shoot with Jayna, I decided to add the column as a background prop and created it very easily in Bryce 5.5, I rendered it with a matte so it was easy to bring into Photoshop as a separate layer. Jayna was photographed against a gray wall and I extracted her using a combination of techinques including the extraction tool, the magic background eraser and painting into a layer mask.
Jayna lives in LA and will be spending the next 3 months in Monte Carlo as part of the Belly Dance Superstars.
