Magnifying Camera: With all these notes taken at the microscope, the poor man then inserts his little negative into a copying and magnifying camera, and proceeds to realize all these various positive pictures, hitherto only sketched out in art or scientific idea, and makes them of any size that he can afford.
'He use of small cameras to produce big pictures was rst suggested as a convenience. In 1840 John W. Draper sported that he was making enlarged copies of daguer-:o typesnth a view of ascertaining the possibility of diminish-3g the bulk of the traveler's Daguerreotype apparatus, n the principle of copying views on very minute plates, rith a very minute camera, and then magnifying them absequently to any required size, by means of a station-ry apparatus.
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. |
