On set
Reading a script as a DP
Breaking down a scene into shots, beats, and visual decisions before a single light is hung

Where the shoot really happens
Most amateur DPs make the same mistake: they show up on the day of the shoot, look at the location, and start improvising. By the time they've figured out where the camera should go, half the day's available time is gone — and the choices they make are reactive to constraints rather than driven by intention.
Working cinematographers do almost all their decision-making off the set. Pre-production is where the movie gets made. The shoot is execution.
The starting document for every cinematographer's prep is the script.
The DP read
A DP reads the script differently than the director or actors do. The director reads for performance, theme, structure. The DP reads for visual problems and visual opportunities.
On the first read-through, you're identifying:
- Locations. How many distinct places? Interior or exterior? Day or night?
- Times of day. When does light change matter? Sunset scene? Cold morning?
- Cast count per scene. Two people in a room is different from twelve.
- Movement. Static scene or characters moving through space?
- Mood beats. Where does the scene shift emotionally? Where should the visuals shift with it?
- Practical lighting opportunities. Lamps, windows, fires, screens — anything the script puts in the world.
- Constraints. Wardrobe colors, specific props, location restrictions.
You'll read the script three or four times before you start any prep work in earnest. Each pass surfaces different observations.
The breakdown
After the read-throughs, you create a breakdown — a document that captures each scene's visual requirements in one place. Most DPs use a spreadsheet or a structured document. For each scene:
| Field | What goes here |
|---|---|
| Scene number | From the script |
| Slugline | The "INT. KITCHEN — NIGHT" line |
| Synopsis | One sentence — what happens |
| Location | The actual physical location |
| Time of day | And how it relates to other scenes' time |
| Cast | Who's in it |
| Practical sources | Lamps, windows, fires the script mentions |
| Visual idea | One sentence — what's the look |
| Equipment | What gear this specific scene needs |
| Concerns | Anything that might be hard |
Even on a 5-minute short you might end up with 20+ scenes after breaking down. The discipline of one row per scene forces you to think about each one independently.
The "look book" / visual references
Alongside the breakdown, working DPs assemble a look book — a collection of reference images for the visual style of the project. Sources:
- Stills from films with similar mood, tone, period, or location
- Paintings (Vermeer for window light, Caravaggio for chiaroscuro, Hopper for American interiors)
- Photographs (Saul Leiter, Vivian Maier, Stephen Shore, William Eggleston are common DP references)
- Magazine editorials
- Your own previous work
The look book gets shared with the director before prep starts. It's the visual vocabulary you'll use to talk about the film. "I'm thinking like the diner scene in Inside Llewyn Davis" carries way more meaning than "moody warm light."
Scene breakdown: a worked example
Imagine the script reads:
INT. SARAH'S APARTMENT — NIGHT
Sarah sits at the kitchen table, picking at takeout. The phone rings.
SARAH (into phone)
I'm fine.
She listens. She isn't fine.
What the DP extracts:
Location: A kitchen, likely small, with a table. Need to scout. Time of day: Night. Implications: warm artificial light. Window outside is dark. Practicals: Probably an overhead kitchen light or pendant. Possibly a wall sconce. The script doesn't specify — DP gets to choose. (Decision: a single pendant over the table, warm bulb, will be our practical and our key.) Cast / blocking: One actor, sitting. Phone in hand. Movement is minimal — picking at food, listening. Mood beat: "She listens. She isn't fine." The scene's pivot. Visually, this is where the lighting/composition should say something. Options: closer shot, lower light, eye-line drop into shadow, dolly slowly in. Decision happens with the director. Coverage plan:
- Master / wide of Sarah at the table (establishes geography)
- Medium of Sarah taking the call (the "I'm fine")
- Close-up on Sarah's face during the listen (the pivot moment)
- Maybe an insert of the phone or the takeout (texture)
Lighting plan:
- Practical pendant over table — replace bulb with dimmable LED at ~2,800K
- Hidden cinema fixture (1×1 LED panel) just off-frame, dialed to look like pendant overspill
- Negative fill flag on the shadow side of Sarah's face — pushes the contrast up
- Window behind Sarah: probably dark, possibly a very dim cool source outside for the suggestion of "night" through the glass
- For the close-up pivot, consider dimming the cinema fixture in real-time so her face slips into deeper shadow as she realizes
That's a one-minute scene that just got 10 minutes of pre-production thinking. Multiply that by all the scenes and you understand why the work happens before the shoot.
The shot list
After breaking down each scene and meeting with the director to align on coverage, the DP makes a shot list — usually a spreadsheet, sometimes drawings.
Each row:
| Shot # | Scene | Size | Angle | Lens | Movement | Notes |
|---|---|---|---|---|---|---|
| 1A | 3 | WS | Sarah's POV from doorway | 24mm | Static | Establishing |
| 1B | 3 | MS | Sarah at table | 35mm | Static | Phone rings |
| 1C | 3 | CU | Sarah's face | 85mm | Slow push | Pivot moment |
| 1D | 3 | Insert | Phone in hand | 50mm | Static | Cutaway |
Shot sizes follow standard abbreviations:
- WS Wide Shot
- MS Medium Shot
- CU Close Up
- ECU Extreme Close Up
- OTS Over The Shoulder
- POV Point Of View
A typical narrative scene has 4-8 shots. Documentary and run-and-gun work uses fewer planned shots but has the same intentional thinking happening in real time.
The blocking diagram
For complex scenes (multiple actors, multiple positions, complex movement), DPs draw a blocking diagram — a top-down view of the location showing actor positions, camera positions, light positions, and lens choices for each setup.
Even a rough hand-drawn one is enormously useful. The diagram lives in the shot list document and gets referenced during the shoot when the AD asks "what's next?" The DP doesn't have to remember where the camera was supposed to go — it's drawn.
Lighting plan / lighting plot
For more complex setups, especially studio work, the DP (or gaffer) draws a lighting plot: top-down view of the location showing every light position, what fixture, what intensity, what gel, what shaping. This is the document the gaffer pre-rigs from before the DP arrives on the morning of the shoot.
The discipline of drawing the lighting plot forces you to commit to choices before you can second-guess them on set under time pressure.
The director conversation
Pre-production lives or dies on the relationship between DP and director. Working DPs spend significant time in pre-production sitting across from the director going through the script page by page, discussing:
- What does each scene feel like?
- Where are the emotional beats?
- What visual choices support those beats?
- What are the must-have shots?
- What are the want-to-have shots if time allows?
This isn't about agreement — sometimes the DP and director disagree about how a scene should look. The conversation is about understanding the director's intent so the DP can serve it (or push back where they have a strong opinion). The worst outcome is a DP who guesses what the director wants and gets it wrong on the day.
Common mistakes
- Showing up to prep with no breakdown. "I'll figure it out on the day" is a recipe for losing the day.
- Look book that's just 2001: A Space Odyssey references. Be specific. The look book is a tool, not a portfolio piece.
- Shot lists that ignore production realities. A 30-shot day is rarely achievable. Bake in honesty about what you can actually shoot.
- Skipping the blocking conversation with the director. You'll show up on the day and discover the actors stand somewhere you didn't expect — and your light plan doesn't fit.
- No alternates. Plan A doesn't survive contact with the set. Have a Plan B for every key shot.
What to practice this week
Pick any short film script you can find — a friend's script, a published one online (search "short film script pdf"), even the first 10 pages of a feature script.
Do a full breakdown. Write out each scene's row in the breakdown table. Then pick one scene and:
- Draw the location as you imagine it (top-down)
- Block the actors on the diagram
- Plan 4-6 shots, lens choices, sizes
- Sketch the lighting (key, fill, back, practicals)
Show the result to a friend who hasn't read the script. They should be able to see the scene in their head from your plan.
That ability — translating words on a page to a planned, intentional, watchable scene — is the working cinematographer's craft. The camera comes later.
