Land Camera Land Camera Land Cameras are instant cameras with self-developing film named after their inventor, Edwin Land, who created them while working for Research Row in Boston, Massachusetts. They were manufactured by Polaroid between the years of 1947 and 1983. Though Polaroid continued producing instant cameras after 1983, the name 'Land' was dropped from the camera name since Edwin Land retired in 1982. The first commercially available model was the "Polaroid Land Camera Model 95", which produced prints in about 1 minute, was first sold to the public on November 28, 1948. The process, invented by Polaroid founder Edwin Land, was
Polaroid (polarizer) component of the electric field perpendicular to the line of crystals however can cause only small movements in the electrons as they can't move very much from side to side. This means there will be little change in the perpendicular component of the field leading to transmission of the part of the light wave polarized perpendicular to the crystals only, hence allowing the material to be used as a light polarizer. This material, known as "J-sheet", was later replaced by the improved "H-sheet" Polaroid, invented in 1938 by Land. H-sheet is a polyvinyl alcohol (PVA) polymer impregnated with iodine. During
