EMI2.1
Der Teil 14 der Prüfstelle, der mit der Normalfärbung ausgestattet ist, ist der Bequemlichkeit halber von vorneherein mit jedem ein Negativ bildenden Teil des Filmes verbunden. Diese Anordnung ist jedoch durchaus nicht notwendig und es ist ohneweiters ersichtlich, dass eine Scheibe mit Normalfärbung von der Kamera weggelassen und statt dessen in der Tasche des Photographen aufbewahrt sein kann, um bei der Anstellung des Vergleiches mit der Prüfstelle in nächste Nähe zur Prüfstelle gebracht zu werden.
In der in den Fig. 5,6 und 7 dargestellten Vorrichtung sind die Prüfstellen 13 nicht in fester Verbindung mit den Teilen, die Normalfärbung besitzen, sondern werden nacheinander in Deckung gebracht mit einem Rande 17 einer Öffnung 15, der mit der Normalfärbung versehen ist, um einen Vergleich mit der veränderlichen Färbung der Prüfstelle zu ermöglichen.
PATENT-ANSPRÜCHE
1. Träger für die lichtempfindliche Schichte von Films, Filmpacks, gekennzeichnet durch lichtempfindliche, den aktinischen Wert des Lichtes messende Prüfstellen, die einzeln für jeden Träger vorgesehen und mit ihm verbunden sind.

EMI2.1
The part 14 of the test station, which is equipped with the normal inking, is connected from the outset to each part of the film that forms a negative for the sake of convenience. However, this arrangement is by no means necessary and it is immediately apparent that a disc with normal coloring can be left out of the camera and instead kept in the photographer's pocket so that it can be brought into close proximity to the test center when making the comparison with the test center will.
In the device shown in FIGS. 5, 6 and 7, the test points 13 are not permanently connected to the parts that have normal coloring, but are successively brought into line with an edge 17 of an opening 15 which is provided with the normal coloring, to allow a comparison with the changing color of the test point.
PATENT CLAIMS
1. Support for the light-sensitive layer of films, film packs, characterized by light-sensitive test points which measure the actinic value of light and are provided individually for each support and connected to it.
