These Camera: Containing the New Optical Laws of the these Camera Obscura or Daguerreotype, demonstrated that converging perpendiculars of the these 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 these camera. Many hand these cameras were even equipped with levels to assure the viewer that he was holding the these 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 these 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 these Camera and tripod makes every job fall into the category of hard labor. Also important is that the cost of everything, these 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 these Camera mounted on top of the these 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-these 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 these Camera obscura. A collapsible hood shaded the ground glass so that the image could be seen clearly.
