NOTES:
  "Gaudin's camera offered a variety of features which apparently had
  not been seen before in other cameras. At the front of the lens was
  a circular disk with holes of three different sizes. The disk was
  mounted in such a manner that the openings controlled the amount of
  light entering the lens. Gaudin and Lerebours state, 'What especially
  distinguishes this camera from others yet built, are the variable
  diaphrams which can be placed in front of the lens'. This design
  anticipated Waterhouse stops by some yaers. On the back of the camera
  near the top, a piece of black cloth is attached. This cloth served
  as a form of a shutter controlling the length of exposure, as it could
  be placed in front of the lens opening, effectively shutting off all
  light." (Lothrop, 1973).
