Light and Shadow Prompt Generator
This skill generates image prompts based on the "Container + Pressure + Cut + Anchor" aesthetic formula. It emphasizes material textures, dramatic lighting, and narrative depth.
Process
1. Materiality & Theme Analysis
- Goal : Establish the "Substance" of the scene.
- Action : Analyze the user's input (or choose a default if empty) to determine the core material palette.
- Rule : Every prompt MUST start by defining the material and atmosphere, not just the subject.
- Bad : "A big room."
- Good : "A cold, damp concrete chamber with water stains on the walls."
- Good : "A rusting industrial corridor filled with steam."
2. Structural Formula Application
Construct the scene using this 4-step formula:
-
Container (The Geometry)
- Describe a repetitive or imposing geometric structure.
- Keywords : "Infinite colonnade", "Towering brutalist walls", "Symmetrical tunnel", "Massive archive shelves".
-
Pressure (The Lens)
- Use wide-angle lenses and low angles to create scale and "pressure".
- Keywords : "24mm wide angle", "Low angle view", "Vertigo inducing", "Towering scale".
- Action : Draw from
resources/variations.json "lens_types" for variety.
-
Cut (The Light)
- Describe light not as illumination, but as a physical object cutting the space.
- Keywords : "Volumetric lighting", "Hard shadows", "Shafts of sunlight", "Chiaroscuro".
- Action : Draw from
resources/variations.json "lighting_styles" for variety.
-
Anchor (The Scale)
- Place a single, small, static element to provide scale.
- Examples : "A lone figure in a red dress", "A single chair", "A small campfire", "A parked bicycle".
- Rule : The anchor must be small relative to the container.
3. Detail Injection (Texture & Props)
- Goal : Make it feel "real" and "lived-in".
- Micro-Details : explicit mention of surface imperfections.
- Examples : "Peeling paint", "Water damage", "Scratch marks", "Dust floating in the light" (Tyndall effect).
- Contextual Props : Add small scatter objects relevant to the theme.
- Theme : Ancient Temple -> Props : "Burnt-out candles", "Fallen petals".
- Theme : Cyberpunk -> Props : "Tangled wires", "Discarded takeout box".
- Theme : Office -> Props : "Scattered papers", "Overturned coffee cup".
4. Assembly & Variety Check
- Combine all parts into a cohesive prompt.
- Negative Prompt : Include a standard negative prompt for this style (e.g., "flat lighting, low contrast, oversaturated, cartoon, 3d render, watermark").
- Final Polish : Ensure it reads like a scene description, not a grocery list.
Example Output Format
Prompt: [Material/Atmosphere] + [Container] + [Pressure/Lens] + [Cut/Lighting] + [Anchor] + [Details/Props]
Negative Prompt: [Standard Negative Prompt]
Usage Examples
Input: "Subway Station" Output: Prompt: Rough, grime-covered ceramic tiles lining the walls of a desolate underground space. An infinite symmetrical subway tunnel stretching into darkness. 24mm wide angle shot from a low perspective, emphasizing the oppressive ceiling height. Sharp, cold shafts of artificial light cutting through the thick, dusty air, creating harsh shadows. A lone commuter standing still on the platform, waiting. Scattered trash and old newspapers on the floor, puddles reflecting the flickering lights. cinematic lighting, photorealistic, 8k.
Input: "Forest Shrine" Output: Prompt: Moss-covered ancient stone surfaces damp with morning dew. A towering natural cathedral formed by massive redwood trees arranged in a natural colonnade. Ultra-wide panoramic perspective looking up at the canopy. God rays piercing through the dense foliage, creating a tyndall effect in the mist. A single small stone idol placed at the base of a tree. Fallen leaves, twisted roots, and floating pollen particles filling the air. mystical atmosphere, intricate texture, unreal engine 5.
