The stereoscopic camera "FED-stereo" hereinafter referred to as camera is designed to permit the amateurs to take stereoscopic photographs in quantity of 21 stereoscopic couples with the exposure size of 24x30 mm on a standard 35 mm photographic film.
The camera is manufactured in two models: "FED-stereo M" and "FED B-O-Y stereo", "FED B-O-Y stereo" differs by the following: - more precise operation of the automatics and shutters; - more precise matching of the pictures of both channels; depth scale of the best stereoscopic view; - another distance numbers on the distance scale; - diaphragm number "5,6" with exposition time "B", - improved design of the film sensitivity setting mechanism.
Cameras may be manufactured with distance scales, expressed in meters or in meters and reef. Reversal and negative black-and-white or color film can be used when taking stereoscopic photographs. A photographer may use a developed reversal film to make stereoscopic slides, the purchased or self-made stereoscopic frames being used for this purpose. A negative film can he used to make pictures on photographic paper to use them as photographs of a common type or stereoscopic couples.
Speaking a little about a stereoscopic photography. Two identical lenses in the camera permit a photographer to make two discriminated flat images on a film, these two images forming a stereoscopic couple which can be projected on a screen through use of the stereoscopic diascope "ETUDE-stereo" thus producing a three-dimensional image picture. In fact, a man sees the surrounding objects in as much as similar manner due to stereoscopic visual perception of his own see the diagram.
Physical nature of a stereoscopic visual perception is as follows. Either eye of a man projects, through its crystalline lens, a flat image of the object seen onto its retina.
Image discrimination is a result of the distance difference regarding different points of the object being viewed. This image discrimination is percepted by the optic cells of a man's central nervous system in a form of the shift of different points scattered in space and viewed in depth. The camera is provided with a paired shutter-diaphragm unit arranged behind the camera lenses.
The shutter is wound and the film is transported by means of a common release lever. The camera is provided with interlocking for the release button and for the shutter winding lever. This provision is made to prevent a mis-operation of the film transport mechanism overlap of the stereospcopic couples. Arrangement of the stereoscopic couples is shown in the figure. Provision is also made for interlocking of the release button when the camera operates in an automatic mode under unfavorable illumination condition.
To permit fine setting of the exposure of a stereoscopic picture there is an illuminated exposure-limiting frame within the field of vision of the viewfinder. The camera is provided with a self-resetting counter of the stereoscopic couples. To facilitate the assembly procedure, one of the exposure frames has a match mark. Unscrew the cover 21 Fig. Insert bushing 23 into the cell compartment. Fit the cover back in place.
For this, set the mode selector 6 Fig. Turn the disk 12 Fig. Direct the camera at some bright object such as window or lamp and gently depress the release button. Interlocking action of the release button indicates that the power source has been fitted in its compartment incorrectly or has become faulty.
Pull up the rewinding head 11 and, while holding it in this position remove the rear cover 7 from the camera as shown in fig. Load the cassette 24 with a film in the camera and release the rewinding head down. Insert the head end of the film under the spring clamp of the receiving coil 25 Fig. Acceptance certificate Exposure size: mm 24X30 Number or stereoscopic couples obtained: minimum 21 Photograph basis: mm Camera, pcs.
