Working as a Gaffer: What Does a Gaffer do?

Responsibilities of a Gaffer:

• The Gaffer executes the cinematographer’s lighting plan.
  
  
• Run the lighting crew. With the support of the Best Boy, the gaffer oversees the lighting technicians—running power, setting fixtures, pre-lighting upcoming scenes or sets, and maintaining lighting continuity across scenes, angles, and shooting days.
  
  
• Electrical safety and power planning. The gaffer, along with the Generator Operator when one is present, is responsible for electrical safety on set. On smaller productions without a Generator Operator, this responsibility falls entirely on the gaffer. This includes planning power distribution, calculating electrical loads, balancing phases, and determining whether house power or a generator is appropriate.
  
  
• Pre-production, prep, and coordination. The gaffer attends prep meetings and location scouts, working closely with the DP and Key Grip to discuss the lighting approach for the project and each scene. This includes determining what lighting equipment, power infrastructure, and crew will be required, while staying aware of schedule and budget constraints. The gaffer also coordinates with production, art department, and locations as needed.
  
  
• Thinking ahead and problem solving. A key part of the job is anticipating problems before they happen. This includes planning for relights, keeping fixtures standing by for close-ups, preparing for schedule changes, and solving issues quickly as they arise—often while time is already being lost.
  
  
• Second set of eyes for the DP. As scenes and sets are being lit—and especially once the camera is rolling—the gaffer acts as a second set of eyes for the cinematographer, watching for unwanted shadows, hot spots, exposure issues, continuity problems, or insufficient light.
  
  
• Improving the image when appropriate. The gaffer should stay alert for opportunities to make a scene more visually interesting. This can be a delicate balance, as some cinematographers prefer strict execution of their plan. With experience and established working relationships, knowing when and how to make suggestions becomes easier.
  
  
• Crew leadership and protection. Beyond task assignment, the gaffer sets the pace and workflow for the lighting department, mentors less experienced technicians, and pushes back on unsafe or unrealistic requests when necessary.

Skills

• Creativity. Gaffing is a mix of creative judgment and technical execution. Creativity matters because not every problem has a textbook solution. You’ll often need to improvise, adapt, or find unconventional approaches to achieve the desired look within real-world limits.
  
  
• High level of technical skill and knowledge. A gaffer must understand lighting equipment inside and out and know how to get the most out of fixtures in a wide range of situations. This includes a working understanding of cameras, exposure, ISO, and sensor latitude so lighting decisions support the image being captured.
  
  
• Strong problem-solving skills. Lights fail. Locations change. Power disappears. Many problems are outside your control. A gaffer needs to quickly diagnose issues and offer practical solutions, often presenting the cinematographer with multiple options based on available gear, time, and budget.
  
  
• Prioritization under pressure. Not every problem can be fixed. A gaffer must quickly identify what affects safety, the image, or the schedule and focus effort there, while letting lower-impact issues go.
  
  
• Fast decision-making. Much of the job involves processing large amounts of information—creative intent, technical limits, crew capacity, and time pressure—and making clear decisions quickly.
  
  
• Anticipation and situational awareness. Good gaffers think ahead. This means tracking sun movement, upcoming coverage, actor blocking, weather, and power limits so lighting choices made now don’t create problems later.
  
  
• Strong communication skills. Clear communication is critical. Instructions must be precise and unambiguous. Small wording mistakes can misdirect the crew, waste time, or create unsafe situations. Effective gaffers communicate calmly, clearly, and consistently.
  
  
• Crew management and morale. Running a lighting crew involves knowing individual strengths, setting pace, and keeping people focused during long or difficult days. A supported crew works faster, safer, and with fewer mistakes.
  
  
• Knowing when to push back. A gaffer must be able to say no—or propose alternatives—when a request is unsafe, unrealistic, or will seriously impact the schedule. Doing this professionally protects both the crew and the production.
  
  
• Patience and tact. Gaffers work closely with multiple departments, competing priorities, and varying experience levels. Patience and tact are essential for negotiating changes and keeping the day moving.
  
  
• Consistency and reliability. Cinematographers and Producers rely on gaffers who deliver steady, dependable results day after day. Reliability builds trust and repeat work.
  

• Physical endurance. Long hours, heavy gear, night shoots, and difficult conditions are part of the job. Physical stamina matters more than people like to admit.

Pouches

A good pouch setup matters more than most people want to admit. As a gaffer, you’re constantly moving, problem-solving, and getting pulled in different directions. Digging through carts or running back to the truck every five minutes is a waste of time.

The goal of a pouch is simple: keep the tools you actually use on your body, without slowing you down or wrecking your back.

What Usually Goes in a Gaffer’s Pouch

This varies by person, but most gaffers carry some combination of:

• Multi-tool or Leatherman
• Knife
• Sharpie/pen & notepad
• Small flashlight and/or laser pointer
• Tape
• Small C-Wrench

Anything bigger than that usually belongs on a cart.

Styles of Pouches

• Belt pouches
• Shoulder or cross body pouches
• Pocket-only setups

Most experienced gaffers end up with a combination of pockets and a light belt pouch they can throw on and off as needed.

Less Is More

The biggest mistake newer gaffers make is overloading their pouch. Heavy pouches:

• Slow you down
• Pull on your lower back
• Get caught on stands, ladders, and doorways

If you haven’t used a tool in the last few hours, it probably doesn’t belong in the pouch.

When Not to Wear One

There’s no rule that says you must wear a pouch all day.

• During long studio days, carts or a small stash might make more sense
• On calm days, you may not need it at all

The pouch is a tool, not part of your identity.

Must Have Tools for Gaffers:

Prep & Production Meetings a a Gaffer

On some jobs the Gaffer and Best Boy are given a few days—or even weeks—of prep time before a project begins. This prep period is critical and is used to handle several tasks that will make the shoot run more smoothly once production starts.

• Read the script. Read it carefully, take notes, and highlight any questions, concerns, lighting cues, or effects. This cannot be overstated—read the script and reread it as needed. Ideally, the script is read before the tech scout, though that isn’t always possible. When time allows, a good approach is to read it before the scout, again after the scout during prep, and then reread the pages being shot either the night before or the morning of the shoot.

• Review look references. Watch any visual references provided by the cinematographer, or anything the director and cinematographer are discussing. A director may reference a specific film or scene, or the cinematographer may want certain scenes to have a particular look. Part of the gaffer’s job is helping achieve these looks, so it’s important to fully understand all references being used.

• Further discuss the lighting approach with the cinematographer. Using information from the script, tech scouts, and look references, continue detailed discussions with the DP. Talk through the overall look and feel of the film, as well as individual scenes. Overhead diagrams can be useful tools during these discussions.

• Lighting package and equipment planning. During prep, the gaffer works with the Best Boy to build the lighting package. This includes deciding on fixture types and quantities, planning backup units, and determining cable, distro, and rigging needs so the plan is achievable within the schedule and budget.

• Power planning and location checks. Prep time is used to assess power availability at each location, including identifying tie-in points, confirming amperage and phase, and determining where generators will be required. Many of these issues are identified during scouts but refined during prep.

• Crew sizing and capability planning. The gaffer uses prep time to evaluate whether the lighting crew is appropriately sized for the schedule and complexity of the shoot. This includes flagging days that require additional manpower or specialized skills such as rigging, DMX, or board operation.

• Schedule review and problem identification. The shooting schedule should be reviewed in detail to identify potential problem days, heavy company moves, large pre-lights, or scenes that may require more setup time than allotted. These concerns should be raised early.

• Rental house coordination. Often in collaboration with the Best Boy, the gaffer participates in coordinating with the rental house, walking the order, confirming availability, planning prep days, and adjusting the package when substitutions are required.

• Attend production meetings. Production meetings are an opportunity to raise concerns and clarify expectations. Typically, the full shooting schedule is reviewed day by day with all department heads present. This is the time to flag issues such as cable runs, additional manpower, special rigging, weather concerns, or any other requirements that may affect lighting. Anything that could make the shoot day run more smoothly—or that other departments or production need to be aware of—should be addressed here.

The Tech Scout

Tech scouting is a critical part of prep for every department, especially lighting. It is essential that the gaffer attends all tech scouts. The tech scout is your opportunity to understand how and where scenes will play out, ask questions, and coordinate with other departments and key crew.

As a gaffer and Best Boy Electric, there are several specific things you need to focus on during a tech scout.

• Discuss the lighting approach with the DP. Talk through the look of the scenes on location. Make diagrams, build lists, and take notes as needed to clarify both creative intent and logistics.
  
  
• Confirm equipment needs. Create equipment lists or confirm that the proposed lighting package and truck lists meet the needs of the locations, scenes, and schedule.
  
  
• Plan cable runs. Identify cable paths and determine safe, practical locations for distro and cable while minimizing trip hazards and interference with other departments.
  
  
• Determine generator and/or truck placement. Establish where generators or lighting trucks can be safely and legally placed, considering distance, noise, exhaust direction, access, and sound department concerns.
  
  
• Identify special equipment and rigging requirements. Flag any need for specialty lighting or rigging equipment, including specialty stands, scaffolding, lifts, condors, or other access solutions, and discuss feasibility early.
  
  
• Establish equipment staging areas. Identify where lighting gear, carts, and distro can be staged without blocking exits, fire lanes, or workflow for other departments.
  
  
• Assess sun position and movement. Identify potential sun issues. Will direct sunlight blast through a window all morning? Will it wrap around the building later in the day? Consider how natural light will change over time.
  
  
• Power availability and tie-in locations. Confirm access to house power, panel locations, amperage, phase, grounding options, and any restrictions that may affect lighting plans.
  
  
• Practical lights and art department coordination. Identify existing practical fixtures and discuss which may need rewiring, dimming, replacement, or duplication. Coordinate early with the art department where lighting and set dressing overlap.
  
  
• Safety considerations beyond electrical. Look for overhead hazards, low ceilings, unstable surfaces, water exposure, and any conditions that could create safety risks once lighting is installed.
  
  
• Contingency planning. Use the scout to think through backup options. What happens if a light can’t go where planned? What are the alternate rigging or placement solutions if access or weather changes?
  
  
• Time and manpower realities. Identify days that require heavy pre-lighting, additional crew, or swing labor. Flag unrealistic schedule assumptions early so they can be addressed before shooting begins.

On Set as a Gaffer

On the first day of shooting, arrive early. As a general rule, aim to be on set 10–15 minutes before call time, but on day one it’s worth pushing that to 20–30 minutes. Use the time to introduce yourself, get oriented, have breakfast, and mentally prepare. The first day is usually one of the most stressful days of the shoot.

If you have a pre-call, get started on cable runs immediately. In most cases the Generator Operator will already be running power for departments that need it early, but you’ll still need to ensure power is brought to set and staged near exterior fixtures or upcoming lighting positions.

When official call time hits, report to the cinematographer while the lighting crew is running cable and pulling fixtures. If possible, have the crew work quietly through the blocking so they’re not disruptive.

Blocking may happen immediately at call time or up to an hour later. If it doesn’t happen right away, continue prepping and staging lighting. When blocking does happen, pay close attention to the following:

• Actor movement. Watch how actors move through the space. This informs where lighting needs to be placed, whether units need to be moved outside, and where the key light may ultimately land.

• Potential lighting problems. Look for issues such as actors stacking awkwardly, standing too close together or too far back, or unintentionally shadowing one another.
  
  
• Cable paths and concealment. Identify safe routes for cable and opportunities to hide it. Sometimes set dressing can be used to conceal cable runs. If necessary, coordinate with the art department to help hide cable safely.
  
  
• Existing practical lamps. Practical lamps are often placed by the art department for visual interest. Take note of them early. Power them, install appropriate bulbs, and add dimmers where possible. Even if they aren’t used immediately, having them ready makes it easy to respond when the cinematographer decides they want them on.

Once blocking is complete, discuss the lighting with the cinematographer. Delegate instructions to the crew and begin lighting the scene. After the scene is lit, there is typically a rehearsal before shooting begins—block, light, rehearse, tweak, shoot. Watch the rehearsal closely and make necessary adjustments.

• Managing last-minute changes. Blocking, performance, and camera movement often change after lighting has started. A gaffer must adapt quickly, adjusting or reworking setups without restarting from scratch and without losing time.
  
  
• Knowing when to stop tweaking. Part of the job is recognizing when the lighting is good enough for camera and when further adjustments will cost more time than they’re worth. Protecting the schedule is part of protecting the image.

When shooting begins, watch takes whenever possible. Look for anything problematic or anything you suspect the cinematographer may not like. Often you’ll catch details that others miss.

• Maintaining continuity. Track lighting continuity across coverage, angles, and shooting days. Scenes are often shot out of order, and it’s the gaffer’s responsibility to ensure the lighting remains consistent and intentional.
  
  

• Monitoring exposure changes. Stay aware of shifts in natural light, weather, and color temperature throughout the day, especially on exteriors or mixed-light scenes, and adjust as needed without waiting to be asked.

For example: an actor exits a room and walks into darkness, even though the next scene takes place in a bright space. In that case, they should be walking toward some kind of light source.

If you know your cinematographer well enough, call in the light you think they’ll want over the walkie while asking them if they’d like it. If they say no, the order can be canceled. If they say yes, the light is already on the way.

This can be a delicate judgment call, but if you have a solid working relationship and can’t get their attention in the moment, it’s sometimes acceptable to set the light, turn it on, and ask what they think. If they hate it, they’ll say so. If they like it, you’ve just made their job easier.

• Crew pacing and safety. Throughout the day, the gaffer sets the pace for the lighting crew, watches for fatigue, and prevents unsafe shortcuts—especially under time pressure.
  
  
• End-of-day planning. Before wrap, think ahead to the next day. Decide what can stay rigged, what must be struck, and what needs to be prepped early. This directly affects how smooth the following day will be.

It’s all about Film Lighting at the end of the day:

At the end of the day, the gaffer’s job is about light. Doing it well requires a deep understanding of filmmaking, lighting, and cinematography, along with a genuine commitment to the craft. Without that foundation, the technical side alone isn’t enough.

To Aspiring Gaffers out there:

If you’re working toward becoming a gaffer, the goal of this guide is to give you the kind of practical overview many of us didn’t have early on. Gaffing can be demanding and stressful, but it’s also one of the most rewarding roles on set. If you care about the work and keep learning, it’s a job worth doing.

Final Thoughts

Gaffing is a technical, physical, and creative job that demands consistency, judgment, and responsibility. It’s not about chasing looks or gear—it’s about solving problems, protecting the crew, and supporting the cinematographer under real-world constraints.

No article replaces time on set. The best way to learn is by working, watching experienced gaffers, and taking responsibility for your own growth. Pay attention, ask smart questions, and keep improving your fundamentals.

If you take the work seriously, the job can be demanding, stressful, and unforgiving—but also deeply rewarding. The results are visible on screen, and the trust you earn is what leads to the next call.
