Bas Relief from the Arch of Constantine, Rome. Artist: Frédéric Flachéron (French, 1813-1883). Dimensions: Image: 12 3/4 × 9 15/16 in. (32.4 × 25.2 cm). Date: 1849.The sculptor, medalist, and photographer Flachéron arrived at the French Academy in Rome upon winning a Prix de Rome in 1839. He married soon after and took over his father-in-law's art supply store near the Piazza di Spagna. After learning the waxed paper negative process in 1848, he began to sell photographic equipment and photographs. His prints were displayed at London's Great Exhibition in 1851 and collected by prominent French artists such as Alexandre Cabanel, Hippolyte Flandrin, and Charles Garnier. The waxing process, a modification of Talbot's calotype method, resulted in a more transparent negative, and thus sharper prints. It became a favored medium for artists working under the conditions of intense sunlight in Rome. Museum: Metropolitan Museum of Art, New York, USA.
