Simple camera consisting of a light-sealed cuboidal box that has a lens fixed to one end, and the photographic film plane on the other. As the primary goal of these cameras is ease-of-use, the meniscus lenses on them have a fixed focus and aperture, with a fixed shutter speed — though advanced models feature adjustable settings. Box cameras became very popular among amateur photographers in the late 19th and early 20th centuries. The Kodak Brownie series, released starting 1900, comprise perhaps the most well known box cameras, though other manufacturers like Zeiss and Agfa have also produced them.
