Description

Direkte- Retusche -am -.Kleinbildnegativ ist beim Vergrößern störend auf dem Positiv sichtbar und auch infolge der Kleinheit des Negativs nicht genau möglich.Direct retouching on the small picture negative is annoying when enlarging Visible on the positive and also not precise due to the small size of the negative possible.

Die Herstellung eines vgr ößerten Negativs, um darauf die Retusche vornehmen zu können, ist zeit-und materialraubend, außerdem verliert das Negativ durch die Umkopierung viel Feinheiten. ` Durch nachstehend beschriebenes Verfahren und das zur Durchführung dieses Verfahrens konstruierte Gerät ist es jetzt möglich, ohne Umweg über ein zu . schaffendes vergrößertes Negativ und ohne Verlust von Feinheiten eine einwandfreie (indirekte) Retusche am Kleinbildnegativ vorzunehmen.The production of an enlarged negative to be retouched To be able to do it is time and material consuming, and the negative also loses it by copying a lot of subtleties. `By the procedure described below and the device designed to carry out this procedure is now able to without going through a too. creating enlarged negative and without loss of subtleties to carry out a flawless (indirect) retouching on the 35mm negative.

Zur Durchführung des Verfahrens wird ein Oberflächenspiegel auf dem Grundbrett eures Vergrößerungsapparates in der Weise angebracht, daß der Strahlengang des durch denVergrößerungsapparat vergrößerten Negativs nach außen ' auf eine feinkörnige Mattscheibe fällt (s. Zeichnung). Das so dem Auge sichtbar gemachte Negativ kann nun leicht auf der Mattscheibe retuschiert werden.To carry out the process, a surface mirror is placed on the Base board of your enlarger attached in such a way that the beam path of the negative enlarged by the enlarger outward to a fine-grained one The screen falls (see drawing). The negative made visible to the eye can can now be slightly retouched on the focusing screen.

Das Photopapier wird nun, wie es bei jedem Kopiergerät der Fall ist, auf die retuschierte Mattscheibe gepreßt und belichtet. Nach Herstellung der benötigten Bilder wird die Retusche von der Mattscheibe gewischt und ist nun frei für die Bearbeitung des nächsten Negativs. Der Spiegel wirft ein seitenverkehrtes Bild auf die Mattscheibe. Deshalb wird, um diesen Fehler zu korrigieren, das Negativ mit der Schichtseite nach oben in den. Vergrößerungsapparat geschoben.The photo paper is now, as is the case with every copier, pressed onto the retouched ground glass and exposed. After making the required The retouching of images is wiped off the screen and is now free for editing of the next negative. The mirror throws a reversed image onto the screen. Therefore, in order to correct this error, the negative is made with the layer side up in the. Magnifier pushed.

Mit dEm zur - Durchführung des Verfahrens konstruierten Gerät, in dem Oberflächenspiegel und Mattscheibe in einem genau festgelegten Abstand und Winkel eingebaut sind, kann das Negativ durch den Vergrößerungsapparat auf jede beliebige Größe gebracht werden.With the device constructed to carry out the process, in the surface mirror and ground glass at a precisely defined distance and angle are built-in, the negative can be enlarged to any desired size using the enlarger Size to be brought.
