135film

135 film, also known as 35mm film, is a film format that has been widely used in the motion picture industry for over a century. It is characterized by a film stock that is 35mm (1.069 in) wide and is typically used in conjunction with a 135 film cartridge.

The 135 film format was introduced in the early 20th century and was initially used for roll film, with a spool of film being loaded onto a camera and exposed in a single session. Over time, the format evolved to include quadrangular film, where the film stock was reshaped to fit into a 35mm plastic cartridge. This led to the development of the 135 film cartridge, which is the most common format used today.

135 film is known for its high-quality images and sharpness, making it a favorite among filmmakers and photographers. It has a high level of exposure latitude, allowing for a wide range of lighting conditions and creating a unique aesthetic. The film stock is also relatively durable, with a long shelf life when stored properly.

135 film has been largely replaced by digital formats in the consumer and professional photography markets. However, it remains widely used in the film industry, with many cinematographers and photographers continuing to shoot on 135 film for its unique qualities and aesthetic properties. The format continues to be produced and distributed by various manufacturers, including Kodak, Fuji, and Ilford.
