Instant camera Instant camera The instant camera is a type of camera which uses self-developing film to create a chemically developed print shortly after taking the picture. Polaroid Corporation pioneered (and patented) consumer friendly instant cameras and film, and were followed by various other manufacturers. The invention of commercially viable instant cameras,are which were easy to use, is generally credited to American scientist Edwin Land, who unveiled the first commercial instant camera, the model 95 Land Camera, in 1948, a year after unveiling instant film in New York City. The earliest instant camera, which consisted of a camera and portable wet darkroom
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
