Description

Verfahren zum Herstellen von Filmen mit Bildreihen und photographierter Tonschrift. Beim Herstellen sprechender Filme, bei denen auch die Töne auf photographischem Wege aufgezeichnet werden, ist es insbesondere aus Betriebsgründen von großem Vorteil, dieTonschrift und die Bildreihe auf einen gemeinsamen materiellen Träger (Film) aufzubringen. Es ergeben sich aber infolge der bei der kinematographischen Aufnahme schwankenden Lichtverhältnisse häufig Unterschiede nm Belichtungsgrad der Bromsilberschicht, und zwar,in der Weise, daß die Bildreihe über- bzw. unterbelichtet wird. Da der gleiche Film aber auch nahe an der Bildreihe die immer normal belichtete Tonzeiichenreihe trägt, lassen sich bei kombinierten Negativen diese Unterschiede durch Entwicklung, Abschwächen, Verstärken usw. nicht ausgleichen. Sie lassen sich nur dadurch beheben, daß die unter- bzw. überbelichteten Negativstellen eine getrennte, entsprechend iabgepaßte Behandlung erhalten. Technisch ist dies so gut wie unmöglich, solange sich die beiden Reihen auf dem gleichen Film befinden.Process for producing films with image series and photographed Tone writing. When making talking films, in which the sounds are also on photographic Paths are recorded, it is of great advantage, especially for operational reasons, to the sound writing and the series of images on a common material carrier (film) to raise. However, it arises as a result of the cinematographic recording fluctuating light conditions often differences nm exposure level of the bromide silver layer, namely, in such a way that the series of images is overexposed or underexposed. Since the same film but also close to the series of images the always normally exposed series of audio characters in the case of combined negatives, these differences can be identified by developing, Do not compensate for weakening, amplifying, etc. They can only be remedied by that the underexposed or overexposed negative areas have a separate, accordingly i got proper treatment. Technically, this is as good as impossible as long as it is the two rows are on the same film.

Erfindungsgemäß wird diese Schwierigkeit dadurch beseitigt, daß das Entwickeln der Negative getrennt erfolgt. Das Aufnehmen kann hierbei entweder auf zwei Filmen geschehen oder auf einem, der aller vor dem Entwickeln geteilt wird. Der Synchronismus wird in beiden Fällen durch die Perforation und durch entsprechende Marken gewährleistet.According to the invention, this difficulty is eliminated in that the Developing the negatives is done separately. The recording can either be on two films happen or on one shared all before developing. The synchronism is achieved in both cases by the perforation and by corresponding Brands guaranteed.

Die Hersitellung der Positivfilme kann erfolgen, indem man die beiden Negativfilme, vorteilhaft nacheinander, auf den gleichen Positivfilm kopiert. Man kann aber auch die beiden Negativfilme vorher der Länge nach miteinander verkleben und dieses so gewonnene kombinierte Negativ wie üblich kopieren.The positive films can be made by using the two Negative films, advantageously one after the other, copied onto the same positive film. Man but you can also glue the two negative films lengthwise to one another beforehand and copy this combined negative as usual.
