Story behind the photograph
Today, I had my wisdom tooth taken out. To focus away from discomfort and pain I started to play with a bit of macro photography. We have a number of sea urchin shells at home, which kids picked out at the beach. I always thought the shells look quite interesting with their radial designs and patterns. For this photograph I have selected rather small shell as these do not have the center hole, so common to bigger urchin shells.
I have suspended the shell on a leg of a small tripod. Set the camera in perfect alignment with that leg so it would not be visible. The emphasize the roundness and textures I have opted for a single, directional light source. This uneven light distribution ads dimension to a photograph like that through little shadows.
