Film projection is the process of displaying a motion picture on a screen using a film projector. The projector shines light through a film reel, which contains a series of images that create the illusion of movement when played in rapid succession. This technology has been used for over a century to entertain audiences in movie theaters and other venues. In modern times, film projection has evolved with the introduction of digital projection systems. These systems use digital files instead of physical film, allowing for higher quality images and easier distribution. Despite the shift to digital, traditional film projection remains popular among enthusiasts and in certain artistic settings.
