Description

  Einrichtung zur Herstellung storeoskopisch wirkender   Auf8ichtsbilder.   



   Die Erfinder haben durch Versuche gefunden, dass die den Gegenstand des Stammpatentes Nr. 68134 bildende Einrichtung eine wesentliche Verbesserung hinsichtlich der Bildwirkung und Bildhelligkeit erzielbar macht, wenn das weisse bzw. ausgebleichte Negativ statt auf dunklem bzw. mit dem Raster gleichfarbigem Rildgrund auf einer spiegelnden Metallfläche, beispielsweise auf einer   versilberten Kupferplatte, hergestellt   wird. Die Ursache ist nach Ansicht der Erfinder darin zu suchen, dass die   Schwärzen   des Bildes, die nach der im Stammpatente beschriebenen Einrichtung durch die dunkle Farbe des Untergrundes erzeugt werden, bei der abgeänderten Einrichtung durch den spielenden Untergrund gegeben sind und infolgedessen tiefer und eindrucksvoller in Erscheinung treten.

   Die Weissen des Bildes hingegen worden bei Anwendung des Verfahrens nach dem   Stammpatento   durch den unter ihnen liegenden schwarzen Untergrund getrübt, während sie sich bei dem abgeänderten Verfahren zufolge des Reflexes der spiegelnden Fläche noch verstärken, so dass eine erhöhte Kontrastwirkung zwischen licht und dunkel eintritt.

  Device for the production of storeoscopic looking images.



   The inventors have found through experiments that the device forming the subject of the parent patent no.68134 makes a significant improvement in terms of image effect and image brightness achievable if the white or bleached negative is on a reflective metal surface instead of on a dark or the same color with the grid , for example on a silver-plated copper plate. According to the inventors, the reason is to be found in the fact that the blackness of the image, which is created by the dark color of the background according to the device described in the parent patent, is given in the modified device by the playing surface and is consequently deeper and more impressive in appearance to step.

   The whites of the picture, on the other hand, were clouded by the black background underneath them when using the method according to the parent patent, while in the modified method they are even stronger due to the reflection of the reflective surface, so that there is an increased contrast between light and dark.
