Multilens Camera: James Wallace Black of Boston had better success: he made several views of that city and of Providence, Rhode Island, in I860; a few years later Nadar took a multilens Camera up in a balloon over Paris to make the first successful photographs of that city.
Almost all of the photographers discussed in this chapter took stereographs as well as the larger single negatives. The paired images made with a twin-lens Camera produce a startling three-dimensional illusion when viewed through a stereoscope, and reveal that wealth of information that is essential to a record photograph.
Because the surfaces of tintypes were not fragile they rould be sent through the mail, carried in the pocket, and nounted in albums. They were processed while the cus-:omer waited. They were cheap, not only because the ma-:erials were cheap, but also because by using a multilens :amera several images could be secured with one opera-ion. After processing, the plate was cut into single pic-:ures with shears.
Containing the New Optical Laws of the Camera Obscura or Daguerreotype, demonstrated that converging perpendiculars of the Camera image were indeed mathematically correct and concluded: "Art has always represented objects geometrically, or as they cannot be seen in the perpendicular and visually, or as they can be seen in the horizontal direction."3 But his findings were ignored. Indeed, amateurs were warned in manuals and instruction books never to tip the camera. Many hand cameras were even equipped with levels to assure the viewer that he was holding the Camera horizontally. |
