Description: The daguerreotype image is formed directly on a silver plated copper plate which was made light sensitive with a surface coating of iodine vapors. It is a direct-positive process, made without a negative. It has a highly reflective surface that sometimes makes it difficult to see the image. The image is reversed - letters will appear backwards unless a special lens or prism is used to take the picture. Daguerreotypes are commonly found in leather or thermoplastic cases. Typical dimensions range from the sixteenth plate (1-3/8 x 1-5/8 inches) to whole plate (6-1/2 x 8-1/2 inches). Portraits are the most common subject matter
