Daguerreotype 1/6th plate
 Elegant man with a moustache and patterned vest.
 He puts a hand in his pocket, leaning on a small table.
 The daguerreotype was the first photographic process, developed by Nicéphore Niépce and later Louis Daguerre, and introduced to the world (except the United Kingdom) by France in 1839. It is both a negative and a positive, hence its characteristic mirror effect. In the 19th century, they were also poetically called "mirrors that remember."
