    EiRrichtung   zur photographischen Aufnahme eines Negativs durch Aufleuchten. 



   Es ist bereits bekannt, auf einer lichtempfindlich gemachten undurchsichtigen Unterlage, vorzugsweise Papier, das Bild aufzunehmen, zu entwickeln und zu fixieren, um das so erhaltene Negativ unter   Aufleuchtung   abermals auf einer lichtempfindlichen Unterlage aufzunehmen, zu entwickeln und zu fixieren, wodurch das Positiv erhalten wird. 



   Zu der erwähnten zweiten Aufnahme eignet sich besonders die in der Zeichnung beispielsweise veranschaulichte Einrichtung. Der die erste Aufnahme enthaltende   Rahmen   wird entsprechend verstellbar von einem Ständer B getragen. Zwischen den beiden Rahmen   Al und A 2,   von denen der letztere das Papier für die zweite Aufnahme enthält, ist das Objektiv C angeordnet. Vor diesem befindet sich eine Blende. Rings um die Blendenöffnung E sind die Beleuchtungskörper F angeordnet, durch welche das Negativ im Rahmen   Al gleichmässig beleuchtet   wird.

   Bei dieser Anordnung wird überdies verhindert, dass die von den   Beleuchtungskörpern   F ausgehenden Lichtstrahlen direkt zum Objektiv C gelangen bzw. sich auf diesem Wege kreuzen, wodurch ungünstige Lichteffekte hervorgerufen werden könnten. Über dem Rahmen A'und der Blende liegt eine licht- undurchlässige Decke.

    Device for photographing a negative by lighting it up.



   It is already known to take up, develop and fix the image on a photosensitive opaque substrate, preferably paper, in order to pick up the negative thus obtained again with illumination on a photosensitive substrate, to develop and fix it, whereby the positive is obtained .



   The device illustrated for example in the drawing is particularly suitable for the mentioned second recording. The frame containing the first receptacle is supported by a stand B in a correspondingly adjustable manner. The lens C is arranged between the two frames A1 and A2, the latter of which contains the paper for the second exposure. There is a panel in front of this. The lighting bodies F, through which the negative in the frame A1 is uniformly illuminated, are arranged around the aperture E.

   This arrangement also prevents the light beams emanating from the lighting fixtures F from reaching the lens C directly or from crossing each other in this way, which could cause unfavorable lighting effects. A light-impermeable ceiling lies over the frame A 'and the panel.
