From spaceweather.com:

“The legend is true. Venus is bright enough to cast shadows. The silhouette on this white screen is framed by the light of the Goddess of Love. French photographer Laurent Laveder took the picture and here he explains how it was done: ‘On Christmas evening, I went to the beach to capture the inconspicuous shadows cast by Venus. I positioned my camera (a Canon 40D) between Venus and the screen and then I made several 30 second exposures at 1600 ISO with a Sigma 30mm lens open at 1.4. The camera’s shadow showed up quite nicely.’ Stitching together consecutive exposures, Laveder created a must-see movie. It shows the shadow moving up as Venus descends into the waves behind the camera.”
