ATTENTION!
To prevent double-exposition of the stereocouples it is necessary to cock shutter lever completely until
it stops.
1. General
The stereoscopic photography will discover for you a new world of exciting and creative activity.
Three-dimensional color pictures will produce for you a vivid effect of presence in scene. 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 24×30 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. Since the eyes are set apart
through a certain distance (basis), the two images of the object being viewed will be presented in a
discriminated form (Bˈ ˈ ˈˈ ˈˈA = B A ). 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 cocked 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 cocking 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.
