What’s the difference between a gaffer and a director of photography (DP)?
Understanding what is a gaffer versus a director of photography helps clarify production hierarchy and responsibilities.
The DP (or cinematographer) creates the overall visual design and lighting concept for the film, making creative decisions about composition, camera movement, and the aesthetic look.
The gaffer executes this vision by managing all electrical and lighting equipment, translating the DP’s creative ideas into practical lighting setups.
The DP creates the overall lighting design and relies on the gaffer and his team to implement his vision. While the DP focuses on the artistic aspects and works directly with the director, the gaffer handles the technical implementation, crew management, and electrical safety. On smaller productions, these roles might overlap, but on professional sets, they work as collaborative partners with distinct responsibilities.
How many crew members does a gaffer typically need, and how does this affect my production budget?
The size of a gaffer’s lighting crew directly impacts your production budget and efficiency.
For small productions or corporate videos, a gaffer might work with just a best boy electric and 2-3 electricians.
Medium-budget productions typically require 4-8 lighting technicians plus a rigging gaffer for pre-lighting work.
Large-scale features can employ 15-20 electricians, multiple rigging crews, and generator operators. Depending on the complexity of the setup, you should plan to shoot between 15 to 40 setups per 12-hour day if you have a large professional crew.
Each additional crew member costs $200-$400 daily, but proper staffing prevents expensive overtime from slow lighting changes. Consider that investing in adequate crew size and pre-rigging teams often saves money through faster daily setups and reduced shooting days.
What qualifications should I look for when hiring a gaffer in different countries?
What is a gaffer’s required qualification varies significantly between territories, affecting your hiring decisions for international productions.
In the US, gaffers advance through practical experience without mandatory electrical licenses, though IATSE membership indicates professional standards and training.
The UK requires all gaffers to be qualified electricians with formal certifications like City & Guilds or BS7909 for temporary electrical systems—non-negotiable for insurance coverage.
Australian productions blend both approaches, with some requiring formal qualifications while others accept experienced professionals.
When hiring internationally, verify local regulations through production service companies and ensure your gaffer’s qualifications meet insurance requirements. UK gaffers often provide more sophisticated electrical solutions due to formal training, while US gaffers might offer more creative problem-solving from diverse production experience.
What are typical gaffer rates, and what factors affect their cost?
Gaffer rates vary substantially based on location, experience, production type, and union jurisdiction.
US union gaffers earn between $54.26-65.22 USD/hr ($596.86-$717.42 USD daily minimums for 10-hour days). “Salary-wise you could easily do $150,000 USD a year on your wages. But if you’re savvy, you’re in a big enough market for it, and you own the equipment, too, then there’s a lot more potential for that to go a lot higher” Salary Comparisons of a Rigging Gaffer.
UK rates range from £324.70-£429.05 daily for drama, with commercials paying £443.
Australian productions see general Gaffer rates in major markets like Sydney ranging from AUD $800-1000 for a standard 8-10hr day depending on experience and production scale, however, MEAA minimum award rates are between $2497-3436 ($40.75 /hr) for a standard 40-50 hour week (1st July 2025).
