Auf diese Woiso wird unmitteibar durch eine einzige photographische Aufnahme ein Negativ erzielt, weiches in seinen Dichtigkeitsgraden genau die Plastik des nachzubildenden Originals wiedergibt. Das Negativ oder das danach gefertigte Diapositiv wird auf eine Chromleimschicht gebracht und letztere hierunter belichtet und entwickelt. On this Woiso, a negative is obtained directly through a single photograph, which in its degree of density exactly reproduces the plastic of the original to be reproduced. The negative or the slide made afterwards is placed on a chrome glue layer and the latter is exposed and developed under this. Man erhält dann ein Relief der photographischen Aufnahme, weicher positiv oder'negativ Verwendung finden kann, und eine völlig naturgetreue Nachbildung des betreffenden Objectes bildet PATENT-, ANSPRUCH : Verfahren zur Herstellung photographischer Negative für die plastische Nachbildung von Objcctcn durch Copieren auf lichtempfindliche Chromatschichten, dadurch gekenn zeichnet, dass man ober das nachzubildendo Object während der Aufnahme stetig eine" Schlagschatten in der Richtung nach der Camera zu in der Weise hinwegführt, dasa das ganze Objoct allmahlich in diesen Schatten eintritt. A relief of the photograph is then obtained, which can be used positively or negatively, and which forms a completely true-to-life replica of the object in question PATENT, CLAIM: Process for the production of photographic negatives for the plastic replication of objects by copying onto light-sensitive chromate layers, characterized in that a "drop shadow" is continuously drawn away over the object to be replicated in the direction towards the camera in such a way that the entire object is removed gradually enters this shadow.
