What is the difference between a gaffer and a key grip?

The gaffer heads the electrical department and makes light. The key grip heads grip, shapes and blocks that light with flags and nets, and handles camera support like dollies and cranes. Broadly: electric creates light, grip controls it.

Do I need a gaffer if I am shooting with natural light?

Often yes. Natural-light shooting still involves bounce, negative fill and controlling what comes through windows, which is grip and electric work. Purely available-light documentary shooting is the main exception.

Should the DP choose the gaffer?

Almost always. The pairing is a working shorthand built over projects, and it translates directly into speed on the day. Imposing a gaffer on a DP costs you setups.

Lighting

Gaffer / Chief Lighting Technician

The light master. Executes the DP's vision by designing and rigging lighting setups on set.

The Gaffer Role

The Gaffer is the head of the electrical department and the DP's right hand when it comes to lighting. They translate the DP's visual concepts into practical lighting setups — choosing the right fixtures, positioning them for the desired effect, and managing the electrical team that rigs and operates the lights. A great gaffer understands not just the technical aspects of lighting equipment but the art of shaping light to create mood, depth, and visual interest. They manage power distribution on set, ensure electrical safety, and solve creative lighting challenges under time pressure.

When to Hire a Gaffer

As soon as the DP is attached, and ideally chosen by them — DPs and gaffers work as pairs, and a DP who brings their own gaffer will move faster than one working with a stranger. You need a gaffer on any production with a lighting package. Below that, on available-light or single-source work, the DP may handle it directly.

What to Look For

A DP who recommends them — this is the strongest signal available
Experience with the scale of package you are hiring
Genuine electrical safety competence, including generators and distribution
Speed: a fast gaffer buys back setups every single day
A best boy and crew they can bring with them
