This document discusses multi-camera productions, which involve filming events or programs using multiple cameras simultaneously to capture different angles of the action. There are two main types - live events like concerts, sports and ceremonies, and studio programs like game shows, talk shows and sitcoms. Using multiple cameras allows productions to reduce time and costs by not needing to reshoot from different angles or edit footage together later. It also keeps viewers engaged by providing varied visuals and coverage of unfolding events from diverse perspectives. Multi-camera techniques are particularly useful for capturing live productions in a single take and building emotional connections through reactions shots.
