Description
Verfahren und Vorrichtung zur Aufnahme und Projektion von Photographien, insbesondere von Kinematographien in natürlichen Farben. Zusatz zum Patent 425250. Die Erfindung betrifft .eine weitere Ausbildung des Verfahrens und der Vorrichtung zur Aufnahme und Projektion von Photographien, insbesondere Kinematographien in natürlichen Farben, mit Hilfe von Prismenbiöcken.Method and device for taking and projecting photographs, especially of cinematographies in natural colors. Addition to patent 425250. The invention relates to a further embodiment of the method and the device for taking and projecting photographs, in particular cinematographies in natural colors, with the help of prism blocks.
Nach dem .Hauptpatent soll das auf die Reflexionsflächen des Prismenblockes auffallende Licht nach zwei komplementären Farben gespalten werden, so daß nur der der Farbschicht gleichgefärbte Anteil durchtritt, während der komplementär gefärbte Anteil reflektiert wird. Dies geschieht durch Anbringung einer intensiven Farbstoffschicht auf die Trennungsfläche des Prismenblockes. Es hat sich nun gezeigt, daß zur Ausführung des Verfahrens als Farbstoffe besonders solche mit metallisch glänzender Oberfläche geeignet sind, wenn man diese auf der Trennungs- Farbstoffes, dessen Reflexfarbe seiner eigenen Farbe komplementär ist (Fuchsin, Kristallviolett o. dgl.), so erhält man also einen halbdurchlässigen Spiegel, bei dem der durchgehende Lichtteil dem lflektierten komplementär ist, d. h. ein Filter, das dem seiner Farbe komplementären Teil des Lichtes nicht absorbiert, sondern reflektiert. Enthält das reflektierte Licht außer den komplementären noch andere Strahlen, so lassen sich diese durch Korrektionsfilter-eliminieren.According to the main patent, this should affect the reflective surfaces of the prism block Striking light can be split into two complementary colors, so that only the the color layer passes through the same colored part, while the complementary colored part Proportion is reflected. This is done by applying an intense layer of dye on the dividing surface of the prism block. It has now been shown that for execution of the process as dyes, especially those with a shiny metallic surface are suitable if they are based on the separation Dye, of which The reflective color is complementary to its own color (fuchsin, crystal violet or the like), so you get a semitransparent mirror in which the continuous light part is complementary to the inflected, d. H. a filter that is complementary to that of its color Part of the light is not absorbed, but reflected. Contains the reflected Light besides the complementary rays also let through them Eliminate correction filters.
Nicht immer ist in Luft die Farbe des metallischen Glanzes das Komplement des Farbstoffes. Die Farbe des metallischen Glanzes ist auch abhängig von dem Medium, in dem die Reflexion stattfindet; so zeigt z. B. Patentblau an der Luft einen rötlichen Glanz, während es in Glas gelb reflektiert. Man bringt die Farbschicht als Belag der Hypotenusenflächen zwischen zwei verkittete totalreflektierende Prismen (Abb. i), wobei man durch Auswahl der Glassorten die Reflexionswirkung in gewissen Grenzen beeinflussen kann. Auch der Winkel der günstigsten Reflexion der verschiedenen Farbstoffe ist abhängig vom Medium.The color of the metallic sheen is not always the complement in air of the dye. The color of the metallic luster also depends on the medium, in which the reflection takes place; so shows z. B. Patent blue in the air a reddish one Shine while reflecting yellow in glass. The paint layer is applied as a covering of the hypotenuse surfaces between two cemented totally reflective prisms (Fig. i), whereby the reflection effect can be set within certain limits by selecting the types of glass can affect. Also the angle of the most favorable reflection of the various dyes depends on the medium.
Als Farbstoffträger kann man, wie üblich, Gelatine, Hausenblase, Agar-Agar, Collodium usw. verwenden. Da jedoch das Reflexionsvermögen der Farbstoffe ausgenutzt werden soll, muß der Farbstoffträger mit Farbe voll gesättigt sein. Auch kann man die Glasflächen direkt mit Farbstoff belegen.As usual, gelatine, isinglass, agar-agar, Use collodion, etc. However, since the reflectivity of the dyes is exploited is to be, the dye carrier must be fully saturated with color. You can too Cover the glass surfaces directly with dye.
Jedes Strahlenbündel läBt sich durch zwei Farbspiegel in die drei Grundfarben zerlegen. Entweder man teilt den vom ersten hindurchgelassenen Teil (Abb. 2) oder den vom ersten reflektierten Teil (Abb.3) nochmals, je nachdem der .erste Farbspiegel für zwei oder nur für eine »Farbe« durchlässig ist. Abb. 4 zeigt einen Zerteilungskörper, der zwei sich kreuzende Farbflächen enthält, die beide für zwei Strahlengattungen durchlässig sind, z. B. blaugrün und blaurot.Each bundle of rays can be broken down into the three basic colors by means of two color mirrors. Either one divides the light transmitted by the first part (Fig. 2) or the first reflected part (Figure 3) again after the j e .First color mirror is permeable to two or only one "color". Fig. 4 shows a dividing body that contains two intersecting colored areas, both of which are permeable to two types of radiation, e.g. B. blue-green and blue-red.
Alle Zerlegungs- und Kombinationsvorrichtungen mit halbdurchlässigen Spiegelflächen für Zwecke der Photographie oder Kinematographie in natürlichen Farben lassen sich durch Verwendung von Farbspiegeln zur vollen Wirkung bringen, denn nur durch Farbspiegel kann für jedes Teilbild die ganze in der entsprechenden Farbe vorhandene Energie nutzbar gemacht werden.All dismantling and combining devices with semi-permeable Mirror surfaces for photography or cinematography in natural colors can be brought to full effect by using color mirrors, because only Using a color mirror, the whole can be in the appropriate color for each partial image existing energy can be harnessed.
