Description

Es ist bereits ein Verfahren vorgeschlagen worden, mittels dessen man Tonfilmkopien herstellen kann über ein Dup-Negativ, welches sowohl das Bildnegativ als auch das Tonnegativ enthält.There has been proposed a method by which sound film copies can be made can produce using a dup negative, which is both the image negative and the Contains tone negative.

Die Duplikate von Negativen werden in der Regel so hergestellt, daß man von diesem Negativ zuerst ein Positiv anfertigt und von dem erhaltenen Positiv durch Kopieren und Entwickeln in der-üblichen Weise dann, das Dup-Negativ anfertigt. Dieses Verfahren ist auch bisher für den Tonfilm üblich gewesen. The duplicates of negatives are usually made so that one of this Negative first make a positive and then copy it from the positive obtained and then developing in the usual manner, making the dup-negative. This method has also been common up to now for the sound film.

Es wurde nun gefunden, daß man für den Tonfilm das Verfahren dadurch vereinfachen kann, daß man für das Bild auf dem üblichen, oben beschriebenen Wege das Dup herstellt, daß man aber als Dup für die Tonaufnahme direkt das erhaltene Positiv der ursprünglichen Tonaufnahme benutzt. Dadurch spart man einen ganzen Kopier- und Entwicklungsvorgang.It has now been found that this simplifies the process for the sound film It is possible to produce the dup for the image in the usual way described above, but that as a dup for the sound recording directly uses the positive obtained from the original sound recording. This saves a whole lot of copying and Development process.

Wir gehen also so vor, daß wir von dem für sich aufgenommenen Bildnegativ ein Positiv anfertigen. Dieses Positiv kopieren wir auf einen Duplikatrohfilm und sorgen dafür, daß für die Tonspur genügend Platz unbelichtet bleibt. Auf dem für die Tonaufzeichnung reservierten Streifen belichten wir jetzt das Tonnegativ und entwickeln nun beides gemeinsam. Wir erhalten so das Dup eines Tonfilms, welches sowohl das Bildnegativ als auch das Tonpositiv auf einem gemeinsamen Filmhand enthält und können von diesem in der üblichen Weise durch einen einzelnen Kopiervorgang und eine gemeinsame Entwicklung die gewünschten Kopien ziehen.So we proceed in such a way that we get a positive from the negative picture taken for itself make. We copy this positive onto a duplicate raw film and ensure that enough space remains unexposed for the sound track. On the one for sound recording With the reserved strips, we now expose the barrel negative and now develop both together. This gives us the dup of a sound film, which contains both the image negative and the also contains the positive tone on a common film hand and can use this in the usual way through a single copy and joint development drag the copies you want.
