Description

Filteranordnung für photographische Apparate Gegenstand der Erfindung ist eine Filteranordnung zur Verwendung oder zum Zusammenbau mit photographischen Apparaten, bei denen zur Ermittlung .oder selbsttätigen Einstellung der richtigen Belichtung von Photozellen Gebrauch gemacht wird.Filter arrangement for photographic apparatus is the subject of the invention is a filter assembly for use or assembly with photographic Apparatus in which the correct Exposure of photocells is made use of.

Wenn bei einer Aufnahme Farbfilter (z. B. Gelbfilter) für das Objektiv des photographischen Apparates verwendet werden, so muß auch die Photozelle durch Vorsetzen eines den betreffenden Verhältnissen angepaßten Filters entsprechend abgestimmt oder abgetönt werden. Um hierbei Irrtümer zu vermeiden, indem z. B. nicht zusammengehörige Filter verwendet werden oder eines der beiden Filter vorzusetzen vergessen wird, wird gemäß der Erfindung jedes Objektivfilter mit dem zugehörigen Zellenfilter derart verbunden, daß eine Verwendung der beiden zusammen gewährleistet ist.When taking a picture with color filters (e.g. yellow filter) for the lens of the photographic apparatus are used, the photocell must also be through Providing a filter adapted to the conditions in question, matched accordingly or be tinted. In order to avoid errors here by z. B. not related Filters are used or one of the two filters is forgotten to be inserted, according to the invention, each lens filter with the associated cell filter is such connected that a use of the two together is guaranteed.

Die Verbindung zwischen dem Objektivfilter und dem zugehörigen Zellenfilter kann z. B. eine biegsame, etwa durch eine Schnur; ein Kettchen hergestellte sein; sie kann aber auch eine starre sein, indem die beiden Filter z. B. durch einen Steg miteinander verbunden sind oder eine gemeinsame Filterplatte bilden. Die Filter können auch einem gemeinsamen -Stellwerk zugeordnet sein, durch das zwangsläufig bei der Einstellung eines Filters vor das Objektiv das zugehörige Filter vor die Photozelle gebracht wird.The connection between the lens filter and the associated cell filter can e.g. B. a flexible one, for example by a cord; a chain made; but it can also be a rigid one in that the two filters z. B. by a bridge are connected to one another or form a common filter plate. The filters can also be assigned to a common signal box, which inevitably means When setting a filter in front of the lens, put the associated filter in front of the Photocell is brought.
