Notes on this view:

On February 21, 1947 inventor and Polaroid co-founder Edwin Land demonstrated a new one-step photographic process at a meeting of the Optical Society of America. The process, as Land explained, “produce[d] finished positive pictures, directly from the camera, in about one minute after the exposure.” The system consisted of a specially designed camera—the Polaroid Land Camera Model 95 – and film. The film was a product of three years of experimentation with various means of diffusion transfer. Diffusion transfer describes the transfer of silver salts from undeveloped areas of a photographic image to a receiving substrate. This print is an example of the resulting product: Polaroid’s first commercially available film, Type 40 Land film. Publicly released in 1948, the one-step photographic system was targeted toward the American middle class. The system was designed for easy use and the price, though not cheap, was affordable.
