Shot design, blocking and coverage

Shot design is where the breakdown and the look become specific camera positions, lenses and moves. The DP and director decide how each scene will be staged (blocking), what shots will capture it (coverage) and in what order those shots will be made. These decisions drive almost everything else on the shooting day: the lighting plan, the equipment, the crew size and the schedule. This lesson covers the tools of shot design: shot lists, overhead diagrams and storyboards; the screen direction rules that keep geography clear; common coverage strategies from the classic master-and-singles pattern to the single continuous take; and how to choose lenses and camera positions for real spaces.

Blocking first, coverage second

Blocking is the movement of actors through the scene: where they enter, where they stand, when they sit, cross or leave. Coverage is how the camera records that blocking. In theory blocking comes first and the camera follows. In practice, the director, DP and actors negotiate: a cross that looks natural may put an actor in front of a window the DP cannot light, or a position that is easy to light may feel static.

• Rehearse the blocking before lighting, ideally with the actors in the real space, so the DP sees where light and camera need to be.
• When actors are not available in prep, block with stand-ins or with the director walking the space.
• Mark key positions with tape so camera assistants can measure focus and grips can plan dolly track.
• Expect changes on the day. A shot list is a plan, not a contract.

Shot lists, overheads and storyboards

Three documents communicate shot design.

• Shot list: a numbered list of every planned shot in a scene, with size, angle, lens, movement, equipment and notes. It is the working tool for the camera department and first AD.
• Overhead (floor plan) diagram: a bird's-eye drawing of the set showing walls, doors, windows, furniture, actor positions and movements, camera positions with lens direction, and often light positions. Overheads reveal problems a list cannot, such as two cameras seeing each other or a light stand in a planned dolly path.
• Storyboards: drawings of each shot as it will appear on screen. Common for action, VFX and complex sequences; optional for simple dialogue.

Many productions also use previsualization (previs): 3-D animatics that block cameras and actors in a digital model of the set. Previs is common for action and VFX, and simple tools now make it practical on smaller shows.

Screen direction and the 180-degree rule

Audiences understand geography from consistent screen direction. When two characters face each other, an imaginary line runs between them. If every camera stays on one side of that line, character A always looks screen right and character B always looks screen left, and the cuts feel natural.

• Crossing the line flips screen direction and can confuse the audience, making characters appear to look the same way.
• The line can be crossed deliberately with a moving shot that carries the audience across, a cut to a neutral shot straight down the line, or a character's movement that redraws the line.
• Directors sometimes break the rule on purpose to disorient the audience at a moment of conflict or confusion.
• Movement direction also matters: a character traveling left to right should keep traveling that way across cuts unless the story turns them around.

Eyelines matter too. In matching close-ups, each actor should look just off the side of the lens, at a consistent distance from it, so their eyes appear to meet across the cut. The camera assistant or script supervisor tracks eyeline marks.

Classic coverage

The most common pattern for dialogue is sometimes called the master and coverage approach.

• Master: a wide shot that covers the whole scene, establishing geography and giving the editor a safety net.
• Medium two-shot: closer, keeping both characters in frame.
• Over-the-shoulder shots (overs): one character seen past the shoulder of the other, one in each direction.
• Clean singles and close-ups: one character without the other in frame, getting tighter for emotional beats.
• Inserts and cutaways: objects, hands, details and reactions.

This pattern gives the editor many choices but takes time: each new size or direction is a new set-up. A typical simple two-person dialogue scene might take six to ten set-ups shot this way.

Other coverage strategies

The choice should come from the breakdown. A scene where timing between characters matters, such as an argument with overlapping lines, may suit cross-coverage. A scene about a character trapped in a situation may suit a long, unbroken developing shot.

Choosing focal length and camera position

Focal length and camera distance together control perspective. From a fixed camera position, changing focal length only crops or widens the frame. Changing camera distance changes perspective: the relative sizes of near and far objects and how compressed the space feels.

• Wide lenses close to the subject exaggerate depth, make rooms feel larger and faces more distorted at very close distances.
• Long lenses from far away compress depth, flatten faces flatteringly and isolate subjects from backgrounds.
• For close-ups, many DPs work between about 40 mm and 85 mm on Super 35 for natural facial proportions, but deliberate choices outside that range can be powerful.
• Camera height carries meaning: eye level feels neutral; low angles can make a character feel powerful or threatening; high angles can make them feel small or observed.

Shooting order

Coverage is rarely shot in story order. The usual principle is to shoot all the shots that share a lighting direction and set dressing before turning around.

• Shoot the master first so the scene's blocking and continuity are established, unless the master is the least important shot.
• Then shoot all coverage facing one direction (for example, everything favoring character A, looking toward one wall), then turn around and shoot the reverse.
• Shoot inserts and cutaways at the end or with a second unit, unless an actor's hands are needed.
• Consider performance: some actors give their best early, so the director may want their close-up first. The DP should know this and plan lighting so the close-up can be shot early if needed.

Each turnaround means relighting, moving equipment and resetting background action, which often takes 30 to 60 minutes. Minimizing turnarounds is one of the most effective ways to save time.

Coverage for performance and editing

The editor needs options that serve performance, not only geography.

• Overlap action between shots so the editor can cut on movement: if an actor stands at the end of the master, start the close-up before they stand.
• Get reactions as well as lines. In many scenes the listener's face carries the story.
• Provide clean entrances and exits, and hold at the end of takes so the editor has room.
• Shoot cutaways that give the editor a way to compress time or fix performance.
• Check eyelines and screen direction for every set-up with the script supervisor.

Two cameras and multiple cameras

Many productions shoot with two cameras routinely: an A camera and a B camera. A second camera can shoot a wider and tighter size at once, cover both actors in cross-coverage, or catch a different angle on action and stunts.

• Benefits: more coverage per take, matching performances, and fewer takes for stunts, children or difficult effects.
• Costs: lighting must work from two positions, often flattening the light; microphones are harder to place when one camera is wide; the second camera needs its own operator and assistants.
• A common compromise is stacking: putting both cameras on the same side and axis, one wide and one tight, so the lighting suits both.

When the plan meets the location

On the day, the real location often differs from the scout: furniture moved, weather changed, an actor proposes a different cross. The DP's job is to adapt the shot list while protecting the essentials: the beats and story moments the scene must deliver. Mark the shot list with priorities (must, should, could) so that when time runs short, the DP and director know which shots to drop or combine.
