Stereo Camera

Kodak Stereo Camera

This Kodak Stereo Camera is a unique 35mm film stereo camera produced from 1954 to 1959. The Kodak Stereo Camera employs two lenses to take twin shots of scenes, which after developed could then be viewed in dedicated 3D image viewers - stereo-viewers, stereoscopes. The lenses support adjustable apertures and variable shutter speeds. The camera is in very good age specific condition, the shutter cocks and fires, all knobs and levers move normally - no other testing performed. This camera contains film in unknown condition.

What is a Camera Obscura?

The camera obscura (Latin; camera = vaulted chamber | obscura = dark, thus darkened chamber or room) is an optical device that projects an image of its surroundings on a screen. It is used in drawing and for entertainment, and was one of the inventions that led to photography. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside where it is reproduced, upside-down, but with color and perspective preserved. The image can be projected onto paper, and can then be traced to produce a highly accurate representation. Using mirrors, as in the 18th century overhead version (illustrated in the History section below), it is possible to project a right-side-up image. Another more portable type is a box with an angled mirror projecting onto tracing paper placed on the glass top, the image being upright as viewed from the back. As a pinhole is made smaller, the image gets sharper, but the projected image becomes dimmer. With too small a pinhole the sharpness again becomes worse due to diffraction. Some practical camera obscuras use a lens rather than a pinhole because it allows a larger aperture, giving a usable brightness while maintaining focus.
