120/220 Medium Format Colour Negative Film Scanning
Medium Format is also called "120" and "220" and 645 and 6 x 4.5 cm and 6 x 6 cm and 2 1/4" and 2 1/4 x 3 1/4" and 6 x 7 cm and 6 x 9 cm and more. All these cameras use the same rolls of 120 and 220 film. They just space out the images differently which leads to all the different sizes. Each format makes an image with one side equal to 6 cm (2 1/4").
Medium format gives far better technical quality than 35mm. 120 film was introduced about 1902 and is still very popular today. 220 film has twice as much film which meant twice as many exposures. 220 film can't be used in all cameras. 120 was the most popular film format in the 1960s. It was replaced about 1970 for journalism use by 35mm with the rise in popularity of the Nikon 35mm cameras.
