Light Lab is a natural-light simulator for preparing prompts for AI-generated images and films.
WHY THIS TOOL
Lighting prompts are often too broad: "golden hour", "cinematic sunlight" or "soft natural light". These phrases suggest a mood, but they do not define the sun's direction, its altitude, the length of the shadows or the way a camera should capture the scene.
Light Lab turns those decisions into a visible system. A geographic position, date and time become a three-dimensional sun path. Weather changes the hardness and diffusion of the light. Photographic settings complete the scene. The result is translated into a prompt, structured JSON or a storyboard.
The goal is not to replace creative judgement. It is to give that judgement a preparation tool.
LIGHT LOCATED IN THE REAL WORLD
Light Lab begins with real coordinates. Choose a city, click anywhere on the map or enter a latitude and longitude. The tool recalculates the solar path for the selected date.
The visualization displays: the solar orbit and major daylight phases; the position of the sun and moon; golden hour; shadow direction and length; changing skies, stars and clouds; the effect of natural light on minimal 3D architecture.
The available locations use recognizable architectural silhouettes from Athens, Dubai, New York, Agra, Paris, London, Giza and Rio. Custom coordinates generate a modular architectural composition.
WEATHER CONTROL
Four weather conditions make it possible to compare different lighting responses: clear sky; light clouds; overcast; mist.
Weather affects contrast, shadow softness, cloud visibility, atmosphere and prompt language. It does not change the sun path. It changes how sunlight reaches the scene.
PHOTOGRAPHIC CONTROL
Light Lab includes a camera panel that combines lighting direction with a photographic intention. You can control: focal length; aperture; ISO; shutter speed; white balance; sensor type; ND filter strength.
Locked mode keeps the same settings throughout the day. Auto shutter compensates for changing light through shutter speed. Preview applies focal length, exposure and a subtle color correction to the 3D scene.
Presets provide quick starting points for sharp architecture, cinematic daylight, golden-hour portraiture, long exposure, handheld documentary work and frozen motion.
WHAT LIGHT LAB GENERATES
PROMPT
The generated prompt describes location, date, local time, weather, solar altitude and azimuth, light quality, shadows and photographic settings. It also includes safeguards against contradictory suns, random shadow directions, excessive HDR and flat ambient light.
JSON
The JSON output exposes the same decisions as structured data: coordinates, weather, sun, moon, atmosphere, camera and rendering parameters. It can become part of a creative pipeline, a generation tool, shot documentation or an experimental interface.
TECHNICAL PDF
The one-page PDF combines: a scene capture; geographic position; weather conditions; sun and moon data; camera settings; the generated prompt.
SOLAR STORYBOARD
Interesting light does not exist at a single moment. It evolves. The Solar Storyboard creates 3, 5 or 8 keyframes across the day. Each frame contains: an editable time; a daylight phase; recalculated solar parameters; matching camera settings; an independent prompt.
Selecting a frame moves the simulation to that moment. Markers also appear on the main timeline. Morning, noon, golden hour and dusk can be compared without losing consistency across location, weather or camera settings.
HOW LIGHT LAB WORKS
Choose a location from the menu or click the map.
Select a date and adjust the coordinates when needed.
Choose a weather condition.
Move through the timeline to observe changing light.
Open Camera to define the photographic intention.
Copy the prompt, inspect the JSON or build a storyboard.
Export the technical sheet to preserve or share the setup.
Focus mode removes secondary panels and gives more room to the scene, timeline and camera controls.
WHO IS IT FOR
Light Lab is designed for creative directors, photographers, filmmakers, architects, designers, AI image makers, educators and production teams who need more coherent natural light.
Use it to:
write more precise prompts;
prepare a consistent image series;
compare different times and weather conditions;
document a photographic intention;
teach the fundamentals of solar movement; prepare a sequence before generation.
A VISUALIZATION TOOL, NOT A PHYSICAL ENGINE
Light Lab is an experimental direction and preparation tool. Its calculations and visualization provide a coherent representation of natural light, but they do not replace certified solar-analysis software, a physically based renderer or measurements from a real location.
Its purpose is simpler: make a lighting intention visible, adjustable and transferable.
