Every movie you have ever loved had someone whose whole job was deciding how it looks. That person is the cinematographer, also called the director of photography, or DP. They run the camera and lighting crews, choose the lenses and cameras, shape every scene with light, and often help set the final color of the finished film.
The title sounds like two jobs, and in a way it is. According to Wikipedia, the cinematographer is responsible for the recording of a film and makes the artistic and technical decisions related to the image. The American Film Institute describes cinematography as the art of telling a visual story through light, color, lens choice, camera movement, and what sits inside the frame.
This guide explains what the role covers, who works under the DP, how the job fits with the director, and why the same credit sometimes appears under two different names.
What does a cinematographer actually do?
Think of the cinematographer as the person in charge of the picture itself. The American Film Institute puts it plainly: the cinematographer is in charge of achieving the visual look and feel of a film, both technically and creatively. That covers a long list of choices.
- Which camera and lenses the production uses.
- How each scene is lit.
- Where the camera sits and how it moves.
- What the frame includes and what it focuses on.
- How the final color grade shapes the finished look.
Some of these decisions happen long before anyone shouts action. The job starts in pre-production, when the DP works with the director to plan the look, hires their team, and settles questions about equipment. It continues after the shoot ends, because cinematographers are often involved in the grade, the post-production step that tweaks the color and look of the final film.
That is the part viewers rarely think about. A movie's mood often lives in the color. A cold, gray palette tells a different story than warm golden light, even when the script is identical. The cinematographer helps steer that outcome from the first planning meeting to the final pass in the grading suite.
How does the DP work with the director?
The cinematographer reports to the director. The director describes what a scene should feel like visually, and the DP figures out how to get there. How much freedom the DP gets depends on the partnership.
According to Wikipedia, some directors give their cinematographer complete independence, while others specify exact camera placement and lens selection. That level of control is less common once a director and DP have worked together for years and settled into a rhythm. Most of the time, the director sets the goal and leaves the method to the specialist.
It is a bit like an architect and a builder. The architect draws the house. The builder knows which walls can carry weight and which materials will hold up. Neither can do the other's job, and the house only stands when both agree on the plan.
Who else works in the camera and lighting departments?
A cinematographer does not carry the image alone. The camera and lighting departments are small villages, and the DP is the mayor.
- Camera operator. Controls the camera during takes and frames the shot through the viewfinder. Some DPs operate the camera themselves, but many hand the job to a specialist.
- First and second assistant camera. These crew members make sure the right lens is on the camera and pull focus during a take, keeping the subject sharp as actors move.
- Gaffer. The chief electrician, in charge of designing and often executing the lighting plan. The DP approves that plan so it matches the visual idea of the production.
- Key grip and grips. Under the DP's direction, they build the camera's movement: dollies, tracks, tripods, and cranes.
- Video assistant operator. Displays the recorded image on monitors so the director and others can watch and evaluate each take.
There is also a unit still photographer, who takes pictures during filming for publicity and to help the team track continuity between takes. Every one of these roles exists to serve one thing: the picture the DP and director agreed on.
Why do some credits say 'cinematographer' and others 'director of photography'?
If you have read end credits, you have seen both titles. They mean the same job. So why the split?
According to film data analyst Stephen Follows, the two terms are interchangeable in most real-world situations. The historical reason is that national film industries evolved separately, so different labels grew up for the same role. The modern reason is simpler: some people doing the job simply prefer one credit over the other.
Follows studied the top 200 US-grossing films for each year across two decades, covering 4,000 films released between 1997 and 2016. He found that 58.4% of those films used "director of photography," while 40.8% used "cinematographer," with a small remainder using other terms such as "photographed by." The preference also shifts by genre: big-visual films like fantasy and science fiction lean toward "director of photography," while dramas and romances more often use "cinematographer."
For readers, the practical takeaway is easy. Either credit means the same person ran the camera and lighting departments and shaped what you saw on screen.
What this means for how you watch
Our analysis of how the role breaks down points to one habit worth trying: watch a scene once for the story, then once for the light. Notice where the camera sits, what it lets you see, and what it withholds. A close-up shot tightly frames a performer, which is why it lands with such force. A slow dolly, a wheeled camera platform, can make a hallway feel endless or a conversation feel intimate.
Silent-era filmmakers understood this before sound existed. With no dialogue to carry meaning, films of that period depended on lighting, acting, and design, which made cinematography central to the art form from the start. The craft has only grown more specialized since artificial lighting and faster film stocks arrived, which is why the role split off from the director in the first place.
The profession also has a long institutional history. The American Society of Cinematographers formed in Hollywood in 1919 as the first trade society for the craft, and similar groups followed in other countries, including the British Society of Cinematographers. These societies exist to recognize the cinematographer's contribution to both the art and the science of moviemaking.
One more thing worth knowing: it remains one of the least shared major creative roles on a film. In Follows' dataset, only 2% of movies credited two cinematographers, and just 0.3% listed three or more. When a name appears in that credit, it usually belongs to one person who carried the visual weight of the whole picture.

If this breakdown sharpened your eye, the rest of our film coverage follows the same idea: understand the craft, and the watching gets richer.

The evidence here points to a simple conclusion. Cinematography is not decoration on top of a story. It is a language of light, color, and movement, spoken by a department led by one person whose name you may have skimmed past in the credits. Now you know what that name means.
