  Kassette für photographische Zwecke. 



   Den Gegenstand vorliegender Erfindung bildet eine besonders ausgestattete Kassette für photographische Zwecke, deren Vorteil darin gesehen wird, dass nunmehr dem Photographen die Möglichkeit gegeben ist, jede Sorte photographischer Platten ohneweiters als lichthoffrei zu verwenden. Bei den bisherigen Ausführungen war es nur möglich, Aufnahmen in Zimmern, Innenräumen u. dgl. mit besonderen Platten herzustellen, die als lichthoffreie Platten in den Handel kamen. Dem Liebhaberphotographen war also ein zweckentsprechendes Photographieren nur durch Mitführen von allerlei Plattensorten möglich. 



   Mit der nachstehend beschriebenen Einrichtung ist man in der Lage, jede Aufnahme mit jeder beliebigen Platte herzustellen und es zeigt sich auch namentlich für den Berufsphotographen ein erheblicher Vorteil, da er manche hochempfindliche Platte nicht lichthoffrei erhalten kann, weil die Empfindlichkeit einer Platte durch die in der Fabrik zu bewerkstelligende Lichthoffreimachung in ihrem Werte und Ausmass sehr herabgedrückt wird. 



   In der Zeichnung ist ein Ausführungsbeispiel in zwei Figuren dargestellt, und zwar zeigt :
Fig. i eine Doppelkassette,
Fig. 2 eine einfache Kassette. 



   Gemäss der Erfindung wird die mit Schieber   a1   versehene Kassette a mit einer matten, dunkelroten Rückwand b versehen, welche sich gleichmässig an die Platte c anpresst. Die hierbei erzielte Wirkung zur Erreichung einer lichthoffreien Aufnahme ist folgende :
Durch die Anordnung der Rückwand c entsteht eine völlige Durchzeichnung der dunklen Partien des Bildes ohne Überlichten der hellen Stellen, wie Fenster, Horizont bei engen Strassen, Waldaufnahmen u. dgl. 



   Während man also bisher ohne lichthoffreie Platten keine Zimmeraufnahmen machen konnte, ist durch die vorstehend beschriebene Anordnung die Möglichkeit gegeben, mittels einer jeden Platte eine jede Aufnahme machen zu können.

  Cassette for photographic use.



   The subject matter of the present invention is a specially equipped cassette for photographic purposes, the advantage of which is seen in the fact that the photographer now has the option of using any type of photographic plate without any further halo. In the previous versions, it was only possible to record images in rooms, interiors and the like. Like. Manufacture with special plates that came as atrium-free plates on the market. The enthusiast photographer was only able to take appropriate photographs by carrying all kinds of plates.



   With the device described below one is able to produce any picture with any plate and it is also a considerable advantage for the professional photographer, since he cannot keep some highly sensitive plates free of halos because the sensitivity of a plate is affected by the Factory clearance to be accomplished is very depressed in terms of value and extent.



   In the drawing, an embodiment is shown in two figures, namely shows:
Fig. I a double cassette,
Fig. 2 shows a simple cassette.



   According to the invention, the cassette a provided with a slide a1 is provided with a matt, dark red rear wall b which presses itself evenly against the plate c. The effect achieved in this way to achieve a halo-free exposure is as follows:
The arrangement of the rear wall c results in a complete drawing of the dark parts of the picture without overexposure to the bright areas, such as windows, the horizon in narrow streets, forest photos, etc. like



   While up to now it has not been possible to take room photos without halo-free panels, the arrangement described above provides the possibility of being able to take each recording using each panel.
