The story
in December 1943 Edwin Land started his new project for Polaroid company: the instant photography.
February 1947 - the big reveal of the first instant camera prototype - Model 95 using a peel-apart film.
1963 - the introduction of color peel-apart film for Polaroid cameras.
in 1972 the Polaroid SX-70 was introduced. It was the first camera using the now-classic, square frame film format.
The square format evolved and so did the cameras, which resulted in creating the Polaroid 600, the simpler models popular since the first release in 1982
