KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf ein photographisches Objektiv zur Erzeugung von Bildern mit künstlerisch wirkender Unscharfe.The invention relates to a photographic lens for generating images with artistic blurring.
Das Objektiv besteht aus zwei Halblinsen in Verbindung mit einer darunterliegenden Vollinse. Die Halblinsen stehen in einem geringen Abstand voneinander und haben von dem aufzunehmenden Gegenstand einen etwas verschiedenen Abstand. Sie sind einstellbar, indem man sie um den Durchmesser dreht, nach dem sie durchgeschnitten sind.The lens consists of two half lenses in conjunction with one below Full lens. The half lenses are at a small distance from each other and have from a slightly different distance from the object to be recorded. They are adjustable by turning them around the diameter according to which they are cut through.
In der Zeichnung ist diese optische Anordnung schematisch dargestellt.This optical arrangement is shown schematically in the drawing.
Das Objektiv enthält zwei Halblinsen a und a1, die mit den Durchmessern, nach denen sie durchgeschnitten sind, einander zugekehrt sind. Man kann diese Halblinsen erhalten, indem man eine einfache Linse nach einem Durchmesser durchschneidet und die beiden so erhaltenen Hälften voneinander entfernt. Die Hälften sind auch gegeneinander etwas versetzt, so daß eine von ihnen, beispielsweise a, sich etwas näher an dem aufzunehmenden Gegenstand b befindet als die andere a1. Die Fassungen der Linsen α und a1 sind an Drehachsen c und c1 befestigt. Durch Drehung von Schrauben d d1 oder mittels irgendeiner anderen geeigneten Einstellungsvorrichtung kann man die Halblinsen drehen. The objective contains two half-lenses a and a 1 , which face each other with the diameters according to which they are cut. These half-lenses can be obtained by cutting a simple lens according to a diameter and separating the two halves thus obtained. The halves are also somewhat offset from one another, so that one of them, for example a, is somewhat closer to the object b to be picked up than the other a 1 . The mounts of the lenses α and a 1 are attached to axes of rotation c and c 1 . The half-lenses can be turned by turning screws dd 1 or by means of any other suitable adjustment device.
Hinter den Halblinsen liegt eine Vollinse e. Wenn man die Vorrichtung vor den aufzunehmenden Gegenstand setzt, so sieht man auf der Mattscheibe f, solange die Einstellung noch nicht erfolgt ist, zwei getrennte Bilder. Wenn die beiden Halblinsen parallel zur Linse β liegen, so ist eines der Bilder scharf und das andere etwas verschwommen. Indem man die Linsen um ihre Achsen c c1 dreht, so daß ihre äußeren Ränder in der Richtung der Pfeile bewegt werden, so kann man den beiden Bildern die günstigste Stellung zueinander geben.Behind the half lenses there is a full lens e. If the device is placed in front of the object to be recorded , two separate images can be seen on the focusing screen f as long as the setting has not yet been made. If the two half-lenses are parallel to the lens β , one of the images is sharp and the other is somewhat blurred. By rotating the lenses about their axes cc 1 so that their outer edges are moved in the direction of the arrows, the two images can be given the most favorable position in relation to one another.
Wenn man alsdann die Aufnahme macht, so werden beide Bilder gleichzeitig auf dem Negativ festgehalten. Das Positiv besteht alsdann aus zwei verschiedenen Bildern, die aber so nahe aneinanderfügen, daß das Auge sie nicht trennen kann und nur die daraus entstehende künstlerisch wirkende Unscharfe bemerkt, die den Eindruck einer gewissen Plastizität hervorrufen soll.If you then take the picture, both pictures will be on the Recorded negatively. The positive then consists of two different images, the but put them so close together that the eye cannot separate them, and only those from them resulting artistic blurring noticed, which gives the impression of a certain To produce plasticity.
