Filmirullien

Filmirullien, often translated as film roll or film canister, refers to the protective casing that holds undeveloped photographic or motion picture film. These canisters are typically made of plastic or metal and are designed to prevent light from exposing the film before it is processed. They are crucial for preserving the integrity of the film's latent image.

The design of film rolls has evolved over time, particularly with advancements in film formats. For instance, 35mm film, a popular format for both still photography and cinema, is usually stored in small, dark plastic canisters. These canisters have a spring-loaded mechanism or a tightly fitting lid to ensure light-tightness. Larger formats, such as those used in medium or large format photography, might use different types of holders or magazines, but the principle of light protection remains the same.

Motion picture film rolls, especially those used in professional cinematography, are often larger and more robust than those for still photography. They may also feature mechanisms for winding and unwinding the film cleanly. The term film roll can also be used more broadly to refer to the entire length of film wound onto a spool, regardless of whether it is in a protective canister. The careful handling and storage of film rolls are essential for obtaining high-quality images after development.
