Summary: A Gaffer is the chief lighting technician on a film set. Their formal job description makes them the head of the electrical department, responsible for all lighting design and execution. In practice, the role of a gaffer blends creativity, engineering, and leadership. They coordinate with the Director of Photography (DoP), grips, and set electricians to achieve the desired visual storytelling. In 2025, Gaffers combine classic rigging with new digital, eco‑friendly technologies — making them essential for both artistry and sustainability in modern film and television.
The gaffer’s job description can be summarized in one line: the gaffer on a film set is the senior electrician who manages and executes the entire lighting plan. A standard gaffer definition is: “the chief lighting technician responsible for safe and creative use of power and lights during filming.”

The gaffer also maintains tight communication with other departments, balancing artistic goals with practical demands. This combination of oversight and adaptability is what makes the gaffer indispensable to the success of any modern film production.
