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, On the first day of sales, a demonstration on the working of polaroid cameras took place in a departmental store to help familiarize the common public to the product. This demonstration was conducted by the polaroid sales and demonstration crew and was cut short when all the cameras sold out. A year after he unveiled 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.

Roll film[edit]
As the term suggests roll film can be defined as film wound up on a spool that alternates between light-tight backing paper in order to protect the wound up film and this process is repeated until the picture is made. The first roll film camera was the Polaroid Model 95, followed by subsequent models containing various new features. 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).
