Roll film refers to photographic film supplied in rolls rather than sheets, typically including formats such as 120, 220, and 620. Unlike sheet film, roll film allows multiple exposures to be taken on a single roll, making it convenient for medium- and large-format cameras.
Roll film is widely used in professional and enthusiast photography for its ease of handling, ability to produce multiple frames per roll, and compatibility with a variety of cameras and lenses. Photographers appreciate roll film for producing high-quality negatives or transparencies with consistent results across multiple exposures.
