1835, Scott Archer is developing a camera with bottles that the photographer must manipulate in running her hands through black fabric sleeves. This was the first machine sold. Other manufacturers have designed and marketed other cameras without large suite .. Dr. Edwin H. Land, in 1948, product in the U.S.A. his first "Polaroid Land Camera", an instant print camera. That was the first device giving in a minute a sepia image without a laboratory. The modern principle of Polaroid is the inversion / transfer: a development product is placed in a capsule along one of the edges of a kind of sandwich made with the negative and of the final paper. This unit switches between two rollers where the capsule is split and release reactive products. The image of the negative is converted into positive on the carrier of the photo. For some films, the negative is separate and reusable, and for others it is to throw.

 

Polaroid remained alone on the market snapshot for nearly 30 years. Kodak also introduced its own system in 1976 (1977 in Europe) named PR-10.
