History
What made the Polaroid SX-70 a new kind of instant camera?
The folding SLR joined an unusual camera design to an integral film pack that developed its image after ejection.
The Polaroid SX-70 made instant photography more portable and automated by combining camera, film and processing into one system. Its folded shape and self-developing prints made the sequence of taking and receiving a photograph unusually compact.
A pocketable camera system
The individual model history dates SX-70 production to 1972–1981. Edwin Land introduced the folded camera at a 1972 company meeting, and it began selling in Miami later that year before a wider national release in 1973. Unlike earlier pack-film systems, its print emerged automatically and developed without the user peeling it apart.

Inside the film pack
The film pack did more than hold film: it included the battery and layers needed for image formation. The camera’s mirrors and folding body directed the image onto the integral film. These design choices connected the act of framing with the later visible print, while keeping the object itself portable.

Personal camera, public booth
The SX-70 is a useful contrast with a booth because it moves the process into a personal camera rather than a fixed public station. Both promise a short wait for a physical photograph, but one travels with its owner and the other supplies an environment, camera position and sequence. Keep the comparison at the level of workflow, not shared equipment.
