35mm film is probably the most common film format still in use. It became popular throughout the 20th century as an affordable format that would give users a lot of shots per roll, and by the latter years of film’s heyday, the vast majority of SLRs being produced would shoot 35mm film. The size of a full-frame digital camera sensor is based on the size of a single 35mm negative.
This type of film is available in both colour and black and white formats. Kodak and Fujifilm are the most prolific manufacturers of 35mm colour film, while Ilford and Kodak dominate the world of black and white. You will generally get around 36 shots on a single roll of 35mm film – sometimes one or two more, sometimes one or two less, depending on how efficiently the film was loaded.
