Thermal visionSee the heat, lose the face

Thermal vision shows the world as a map of temperature, with warm bodies glowing in white, yellow and orange against cold blues and purples. The audience instantly understands they are seeing through a machine or a non-human eye that tracks life, not identity.

Optical effects

Why it works on screen

Use it when the scene is about being hunted, searched for or watched by something that does not see as we do. Thermal vision can be the point of view of a creature, a drone operator, a rescue team looking through smoke or a border patrol scanning the dark. It serves menace, surveillance, rescue and the cold logic of machines. A scene earns it when the question is where the warm bodies are, and when losing faces and expressions adds to the fear or the distance. It removes emotion from the image, so pair it with normal shots to bring the human stakes back.

The shot list line

Size: Wide shot or medium shot, as a point of view
Angle: Eye level or high, depending on the viewer
Movement: Slow handheld scan or drone drift
Lens: Wide, low-detail look, often with an interface overlay
Duration: 3 to 8 s

Shoot the plate normally or with a real thermal camera, and decide early whether the heat map is captured on set or built in post.

Screenplay

On the page

Thermal vision is legitimate on the page when a device or a creature in the story sees this way. Establish the source, then use a point of view line, for example THROUGH THE THERMAL SCOPE or CREATURE'S POV, and describe what glows and what stays cold. Keep it short. Color palettes, resolution, scan lines and how the effect is produced are for the shot list and the visual effects notes, not the screenplay.

EXT. COLLAPSED APARTMENT BLOCK, IZMIR - NIGHT

Dust still hangs in the air. Floodlights. Silence ordered through a megaphone.

SELIN KAYA (31, rescue helmet, thermal camera in both hands) sweeps the rubble.

ON HER SCREEN: blue concrete, purple steel, nothing. Nothing.

Then, deep in the slabs, a small orange shape. It moves.

Here! Everybody quiet!

Storyboard

In the storyboard

Draw the scene with simple shapes, then color warm areas in yellow and orange and cold areas in blue and purple. Keep faces as blobs with no features. Mark the viewer's scan with an arrow and circle the heat signature the story is about. Note POV and the source (device, drone, creature). Draw the reverse normal shot next to it, so the switch between thermal and human vision is planned.

Pairs well with

Point of view shot

Thermal vision is almost always a point of view. Framing it as a POV shot makes clear whose perception the audience shares, whether hunter, rescuer or machine.

Aerial shot

An aerial shot in thermal view shows bodies moving across dark terrain from above, which suits drones, helicopters and searches where the pattern of heat tells the story.

Reference

Watch it in

Predator (1987)
The hunter's point of view turns jungle and commandos into glowing patches of color, making thermal sight the mark of an alien predator.
The Predator (2018)
The later film brings back the creature's heat-map viewpoint, keeping its crude false colors as instant shorthand for how the hunter sees.

ScreenWeaver

Set it up in ScreenWeaver

Write the device or creature and its point of view into your screenplay, and ScreenWeaver breaks the scene into shots automatically. Open the POV shot, set a wide or medium framing, an eye-level or high angle, a slow scanning movement and a duration of three to eight seconds, and note the thermal look in the shot description. Characters and locations carry from shot to shot, so the rubble matches in both views. Use the AI previsualization to plan the cutting between heat and normal vision.

The prompt behind this clip

This is the exact prompt that rendered the clip at the top of the page. Keep the description of the camera and the light, change the subject and the place.

Thermal vision: a static wide shot of a neon arcade rendered entirely in false-color heat imaging, a cold blue-purple background where the arcade cabinets glow deep violet, while two adult figures walking between the machines glow white-hot and orange along their heads, hands and chests. The image is low-resolution and slightly soft, with a faint scan-line flicker and warm blooming halos around the hottest edges. No fine detail, no visible text, no normal color, just a shifting heat map. No text.

Common mistakes

01
Physics that do not add up
Thermal cameras do not see through walls or glass. Audiences who know that will be pulled out. Keep what glows plausible, or establish a special device.
02
Too long in thermal
Without faces, the audience loses emotional contact. Cut back to normal shots regularly so the stakes stay human.
03
Unclear whose view
If the audience cannot tell who is looking, the menace or the hope disappears. Show the viewer or the device before the first thermal shot.

Questions writers ask

How do you write thermal vision in a screenplay?

Establish the source, a scope, a drone, a creature, then use a POV line and describe the heat: a figure glowing orange behind cold crates. Return to the normal view with a new line. Keep each thermal passage short and purposeful.

Can a thermal camera see through walls?

No. It reads surface temperature, so walls, glass and water block the view. It can show heat seeping through thin materials or residual warmth on a surface, which can be useful clues in a story.

Should I use a real thermal camera?

Real thermal footage has an authentic, low-resolution texture, but it is hard to control and may not match story needs. Many productions shoot normally and build the heat map in post, which allows precise control of what glows.

What is the difference between thermal and night vision?

Night vision amplifies small amounts of visible and near-infrared light, producing a grainy green image with detail. Thermal vision shows heat, producing colored shapes with little detail. One sees in the dark; the other sees warmth.
