Polaroid 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 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 in a single compartment, was invented in 1923 by Samuel Shlafrock.

In February 2008, Polaroid filed for chapter 11 bankruptcy protection for the second time and announced it would discontinue production of its instant film and cameras, shut down three factories and laid off 450 workers. Sales of chemical film by all makers have dropped by at least 25% per year in the first decade of the 21st century. In 2009, Polaroid was acquired by PLR IP Holdings, LLC which uses the Polaroid brand to market various products often relating to instant cameras. Among the products it markets are a Polaroid branded Fuji Instax instant camera, and various digital cameras and portable printers. As of 2014^[update] film continues to be made by the Impossible Project for several models of Polaroid camera, and for the 8×10 inch format.

Polaroid cameras can be classified by the type of film they use. The earliest Polaroids (pre-1963) used instant roll film. Roll film came in two rolls (positive/developing agent and negative) which were loaded into the camera and was eventually offered in three sizes (40, 30, and 20 series). The next generation of Polaroid cameras utilized 100 series "pack film," which required the photographer to pull the film out of the camera for development, then peel apart the positive from the negative at the end of the developing process. Pack film initially was offered in a rectangular format (100 series), then in square format (80 series). Third generation Polaroids, like the once popular SX-70, used a square format integral film, in which all components of the film (negative, developer, fixer, etc.) were contained. Each exposure developed automatically once the shot was taken. SX-70 (or Time Zero) film had a strong following from artists who used it for image manipulation.
