A Sparrow on the Floor of a Cathedral is a series of B&W inkjet photographs of underwater geologic elements, the seafloor, and marine creatures printed on high quality matte paper and bordered with information relevant to the image, such as the vessel, sponsoring organization and where/when I came upon the scene. Linking the images to physical reality, these details nod to the work of nineteenth-century U.S. geological survey photographers like Thomas O’Sullivan.
