Box Camera: Containing the New Optical Laws of the box Camera Obscura or Daguerreotype, demonstrated that converging perpendiculars of the box 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 box camera. Many hand box cameras were even equipped with levels to assure the viewer that he was holding the box Camera horizontally.This trick is never as satisfactory as getting the picture the way you (or your clients) want it on the negative, once and for all, at the time of shooting.Besides, the view box Camera has other advantages which are than 4 x 5. I have shot thousands of pictures with an 8 x 10, and I can tell you that wrestling the dead weight of box Camera and tripod makes every job fall into the category of hard labor. Also important is that the cost of everything, box camera, holders, tripod, lenses and film, goes up when you go into 8 x 10.
To fill their needs, manufacturers began to introduce in the 1890s a new kind of finder: a second box Camera mounted on top of the box Camera with which the exposure was made. It was fitted with a lens of exactly the same focal length of the taking lens; both were focused together. On the top of the finder-box Camera was a ground glass the size of the negative. Within was a mirror, fixed at 45° to the lens axis, which reflected the image upwards, like the eighteenth-century box Camera obscura. A collapsible hood shaded the ground glass so that the image could be seen clearly. |
