The surface of a daguerreotype resembles that of a mirror because images are formed on a reflective silver plate and has to be set at an angle when finishing as if “reflecting” a dark image. Daguerreotypes were prominent from 1840-1855. Daguerreotypes replaced  the photographic process of camera obscura.
