    Artist Statement

    "Backlighting can emphasize the details, delicacy, and texture of a subject. It can also highlight the form, as in this photo of a nautilus shell.

    "The nautilus shell is an example a perfect spiral in nature called a 'logarithmic spiral', which was first described by Descartes. The cutaway of the shell illustrates this type of spiral in the arrangement of its chambers.

    "To emphasize this defining characteristic I backlit the shell and used natural ambient light for the photograph. The backlighting both illuminates the logarithmic spiral and also renders the pleasant complementary colors of blue and yellow.

    "Overall, the backlighting adds drama to the sweep of the nautilus spiral and transforms the depiction of the nautilus into an abstraction."
