The document discusses digital natives, digital immigrants, and different types of documentary films. It defines digital natives as people born in the digital age who are familiar with technology from a young age, and digital immigrants as people born before widespread digital technology who have adapted to new technology. It then discusses three types of documentary films: observational films that simply observe life without interference, participatory films where the filmmaker participates and alters the situation, and performative films that are subjective and experimental. It also outlines three narrative styles for documentaries: voice-over narration, silent narration using title screens, and a hosted narrator who appears on camera and narrates.
