Inexpensive and astonishingly sharp, daguerreotypes were the most popular portrait form of the 1840s and 1850s. One subset of American daguerreotypes, so-called occupationals, showed workers posing with tools of their trade. These images celebrated American craft and labor, their subjects personifying traits like innovation, industriousness, and courage. This daguerreotype reveals that its sitter understood, and accommodated, the daguerreotype process, which reverses the image. To have his unit number read (almost) correctly, the fireman obligingly posed with his belt upside-down, sacrificing the N to get the O and E in the right place. Even in photography’s infancy, people knew how to pose for the camera; from this moment on, self-presentation would be mediated through its lens.
