Turn-of-the-century panoramic camera. "Al-Vista" model.
The lens is mounted on a spring-loaded axle which rotates through about 120°, meanwhile exposing consecutive sections of the film, which is mounted on a semi-circular plate.
Winding tools in various sizes control the speed of rotation through weight and wind resistance.
WPG creates panoramas for Explore Cornell by taking dozens of digital stills per panorama and stitching them with software.
