Seneca Scout Folding Camera, Model 3A, 1915-1925

Folding cameras were designed to be portable and rugged. The lens sits at the end of a collapsible bellows system, often adjustable to provide better focus. The camera's back typically contains 120 roll film, with multiple exposures on a roll. Popular from 1900 until the introduction of 35mm film in 1945, many amateur photographers owned cameras like this.
