Photogravure is a time-consuming, labor-intensive, costly process, near lost art. "Simply put, photogravures are photographs etched into copper and printed traditionally with ink. Their rich velvety matte surface, deep shadows, delicate half tones, and luminous highlights make photogravures some of the most beautiful and tactile images ever printed.
