Land cameras are instant-type cameras with self-developing film manfactured byPolaroid between the years of 1947 and 1983. The first commercially available model was the Polaroid Land Camera Model 95, which produced prints in about 1 minute, and was first sold to the public in November, 1948. The process, invented by Polaroid founder Edwin Land, was to employ diffusion transfer to move the dyes from the negative to the positive via a reagent. A negative sheet was exposed inside the camera, then lined up with a positive sheet and squeezed through a set of rollers which spread a reagent between the two layers, creating a developing film sandwich. The negative developed quickly, after which some of the unexposed silver halide grains (and the latent image it contained) were solubilized by the reagent and transferred by diffusion from the negative to the positive. After a minute, the back of the camera was opened and the negative peeled away to reveal the print. In 1963, Land introduced Polacolor pack film, which made instant color photographs possible. This process involved pulling two tabs from the camera, the second which pulled the film sandwich through the rollers to develop out of
