(38.) PHOTO-ANAMORPHOSES. The transformation pictures known asanamorphoses, which appear to the eyein their original natural proportions byshowing them by means of a rotatingapparatus, offer so many striking effectsthat it will not be out of place to describea method by which these pictures may berepresented by photography. Commercial anamorphoses are figuresdrawn on transparent discs of paper, thelateral dimensions of which are distendedthree, four, or five times their real widths,so that oftentimes merely a confusion oflines is perceptible, which, however, ifrapidly shown by means of a rotatingapparatus, appear to the eye as picturesof correct dimensions. To produce such pictures by the aidof photography, a specially constructedcamera is required, the dark slide of 158 PHOTOGRAPHIC PASTIMES. whichis combined with the rotating discby means of a strap and wheel. ■ %.

Fig. 62 shows thephotographicxameracombined with the rotating disc, to which PHOTO-ANAMORPHOSES. 159 the photograph to be taken is fixed ; Ais the camera, B the lens, C the back ofthe camera, to which the revolving darkslide D is fastened, E the baseboard ofthe camera, F the rotating disc. The dotted line H shows the axialdirection of the rotating disc ; the dottedline I the axial direction of the lens ; thedotted line K the axial direction of therevolving dark slide. To the dark slide D a double pulley isfixed with grooves, the latter being madefor the two cords L and M. The cordL passes over the two small pulleys Oand P to the revolving disc F, in thelateral grooves of which it is embedded,turning by this manner each time therevolving disc together with the darkslide.
