"Terra Firma" uses 35mm film material that I had laboriously* mastered from a 1908 nitrate print of a " Trip Down Market Street", incorporated with other found images of San Francisco’s built environment before the 1906 disaster. Other images have been gathered from archival photographic materials from numerous vantage points depicting the built space of early San Francisco. Some images that have been re-worked are panoramic in scope, and comprised of pans of large format still images taken by Edweard Muybridge in 1878.
