Description

Verfahren zur glanzfreien Beleuchtung von Gemälden u. dgl. Die Erfindung bezieht sich. auf ein Verfahren zur glanzfreien Beleuchtung von Gemälden u. dgl.Method for the luster-free illumination of paintings and the like The invention refers to. on a method for gloss-free lighting of paintings and the like.

Es ist bekannt, Gemälde,Kunstgegenstände u. dgl. dadurch scharf von ihrer Umgebung abzuheben., daß man ein annähernd gleichmäßiges Licht über die gesamte Bildfläche aufprojiziert. ,Sehr häufig müssen diese Projektionsgeräte in der Decke, der gegenüberliegenden Wand , u. dgl. untergebracht werden, so daß die Gefahr besteht, daß für den Betrachter lästibe und störende Glanzerscheinungen durch dieses Licht auftreten. Es ist weiterhin bekannt, eine Schwarzweiß oder eine Farbaufnahme auf den Kunstgegenstand aufzuprojizieren, um die Helligkeits- oder Farbkontraste im Bild selbst zu steigern, wobei die gleichen Nachteile auftreten können, wie im ersten Fall. Erfindungsgemäß soll nun vor das Projektionsgerät ein Polarisationsfilter eingeschaltet werden, so daß die Glanzerscheinung für das projizierte Licht in Wegfall kommt. Durch ungünstige natürliche oder künstliche Beleuchtung ist häufig in Ausstellungshallen oder Galerfen,der Übelstand anzutreffen, daß@ große Teile des Bildes für den Betrachter durch Widerspiegelung der natürlichen Lächteintrittsöffnungen oder der künstlichen Lichtquellen überschleiertsind. Arbeitet man jetzt zusätzlich erfindungsgemäß mit! polarisiertem Licht und bemißt die Intensität des aufprojdzierteri Lichtes entsprechend, dann können die Glanzerscheinungen weitgehend- abgeschwächt werden, da die Grundbi.ldh elligkeit. im Verhältnis zum Glanz gehoben wird, so daß dieser verhältnismäßig geschwächt erscheint. Verwendet man statt gleich:mäßiig aufpro-jizierten Lichtes zur Beleuchtung eine Aufnahme des Gegen, süandes oder Gemäldes, dann nimmt man erfindungsgemäß eine glanzfreie Aufnahme, in-dem man entweder vor das Aufnahmegerät Polarisationsfilter setzt oder bei Verwendung normaler Aufnahmegeräte :die natürliche oder künstliche Beleuchtung des Gegenstandes mit Polarisationsfiltern ausrüstet. Denn bei Verwendung nicht glanzfreier Aufnahmen oder Verwendung nicht pol.aris@ierken gleichmäßigen Lichtes würde der störendte Glanzeffekt noch gesteitgert wenden. Durch -die erfindunigsgemäße Auflagerung eines glanzfreien Bildes auf :den glänzenden Gegenstand. oder seine gleichmäßige Beleuch, tnzng mit) pödarisiertem Licht wird der Glanzeffekt relativ unterdrückt und dadurch eine einwandfreie Bildbetrachtunig gewährleistet.It is known that paintings, works of art and the like are thereby sharply removed to stand out from their surroundings. that one has an approximately uniform light over the entire Projected onto the screen. , Very often these projection devices have to be installed in the ceiling, the opposite wall, etc., so that there is a risk of that for the viewer annoying and disturbing shine phenomena through this light appear. It is also known to have a black and white or a color image to project the art object to the brightness or color contrasts in the Image itself, whereby the same disadvantages can occur as in the first one Case. According to the invention, a polarization filter should now be in front of the projection device be switched on, so that the gloss appearance for the projected light is eliminated comes. Unfavorable natural or artificial lighting is common in exhibition halls or gallery, the inconvenience of encountering that @ large parts of the picture for the viewer by reflecting the natural pool inlets or the artificial ones Light sources are obscured. If you now also work according to the invention! polarized light and measures the intensity of the projected light accordingly, then the gloss phenomena can largely be weakened, since the Grundbi.ldh ellness. is raised in relation to the gloss, so that it is relatively weakened appears. If one uses instead of the same: moderately projected light For illumination, a picture of the object, sand or painting is then taken according to the invention a gloss-free recording, in which one either has a polarization filter in front of the recording device sets or when using normal recording devices: the natural or artificial Equipping lighting of the object with polarizing filters. Because when using not gloss-free recordings or use not pol.aris@ierken evenly The annoying shimmering effect would turn around even further. By -the inventive Superposition of a gloss-free image on: the glossy object. or his Even lighting, dancing with) podarized light, the gloss effect becomes relative suppressed and thereby a flawless image viewing is guaranteed.
