NOTES:
  "Rigid-bodied all-metal camera for making 450 exposures, approximately
  2 x 2 mm. on 4.5 x 8.5 cm. wet-collodion plates. Designed by René
  Prudent Dagron, Paris, France.
  This camera is but a single element in an elaborate system used by
  Dagron to produce microphotographic images. In actual use, the camera
  was positioned at the end of a "Chambre Noir". The collodion negative
  which was to be photographed normally measured 4 x 5 inches, was
  fitted at the opposite end. The entire unit was placed with the
  negative end against a window; however, artificial illumination was
  used on occasion. After the exposure was made and the plate processed,
  the images were examined microscopically for flaws. The acceptable
  images were then cut out of the plate by means of a diamond stylus."
  Lothrup, 1973.
  After 1860, the images were usually permanently mounted to a Stanhope
  lens, which magnified the image. These images were commonly mounted in
  jewelry.
