Description

Verfahren zum Skelettieren von Photographien Die Erfindung betrifft Verfahren zum Skelettieren. von Photographien und zäum Vorbereiten von Gelatinesilbersalzemulsionsschichten für das Skelettieren.Methods of Skeletonizing Photographs The invention relates to Method of skeletonizing. of photographs and preparing gelatin silver salt emulsion layers for skeletonizing.

Unter Skelettierung versteht man die Umlagerung der bei der Entwicklung einer belichteten Schicht zunächst in nebelartig gleichmäßiger Verteilung entstehenden.geschwärzten Silberteilchen in die Skelettform des vorherigen Nebels, die sich dann von einem helleren Hintergrund mit dem Charakter einer Strichzeichnung abhebt.By skeletonization one understands the rearrangement of the development an exposed layer initially in a fog-like uniform distribution resulting.schwarzten Silver particles in the skeletal shape of the previous nebula, which are then separated from one another lighter background with the character of a line drawing stands out.

Die Erfindung besteht darin, daß für zu skelettierende Schichten quellarme Gelatine verwendet oder die Quellfähigkeit der Gelatine herabgesetzt wird. Man kann beispielsweise die unbelichteten Platten, Filme u. dgl. mehrere Male wässern und dann wieder eintrocknen lassen. Das Eintrocknen kann man, wie bereits früher vorgeschlagen, bis zum Dörren steigern. Es zeigt sich weiter, daß bei derart vorbehandelten Schichten die Skelettierung bedeutend feiner ausfällt und daß auch die Gefahr des Abschwimmens der Gesamtschicht bei zu hohen Badtemperaturen vermindert wird. Während es nämlich sonst bei zu hoher Temperatur vorkommen konnte, daß plötzlich die gesamte Schicht sich löste und abschwamm, setzt das Abschwimmen hier klar und deutlich, vor allen Dingen langsam an den Außenrändern ein. Im allgemeinen fällt die Sk elettierung um so feiner aus, je höher die Trocknungsgrade gewählt sind.The invention consists in the fact that there is little swelling for layers to be skeletonized Gelatine is used or the swellability of the gelatine is reduced. One can For example, water the unexposed plates, films and the like several times and then let it dry up again. Drying can be done, as suggested earlier, increase to dehydration. It is also shown that with layers pretreated in this way the skeletonization is significantly finer and that there is also the risk of swimming away the total layer is reduced if the bath temperature is too high. While it is otherwise if the temperature was too high, the entire shift could suddenly occur loosened and swam away, the swimming here continues clearly and distinctly, above all Things are slowly settling in on the outer edges. In general, the scaling falls the finer the selected, the higher the degree of drying.

Eine besonders günstige Wirkung hat es noch, wenn man bei der Trocknung die Schichtseite nach unten nimmt. Bei der umgekehrten Lage können sie in der stark aufgeweichten Schicht, ihrer Schwere folgend, in Richtung nach der Oberfläche der Schicht hin wandern, die auf diese Weise mit Silberteilchen angereichert wird. Dies begünstigt ebenfalls den Skelettiervorgang.It still has a particularly beneficial effect when it is dried takes the layer side down. In the opposite position, they can be strong softened layer, following its gravity, towards the surface of the Migrate towards the layer, which is enriched in this way with silver particles. this also favors the skeletonizing process.
