Recently, Kurt Amsler held one of his underwater photo workshops in St. Cyr-sur-Mer in the south of France.  It was a great opportunity to sharpen my UW-photo skills.

The photo above is a fisheye at about 15m depth. The goal was to highlight the yellow polyps (Zoanthidea) while positioning the diver in bright blue background.

Want to do an estimate how far the polyps have been away from the fisheye’s dome port? It was about 10-20 cm (roughly 5-10 inches). Two flashes were used. One to highlight the corals and the second one obviously for the diver.
