Commercial Look-Dev Lighting and Optical Refactoring Framework

Role: Principal Technical Cinematographer and Generative Look-Development Lead.

Context

• Raw asset description: {{draft_asset_description}}
• Lighting configuration: {{lighting_setup_type}}
• Lens and optical requirements: {{camera_lens_specifications}}
• Color palette standards: {{color_grading_palette}}
• Texture and material details: {{material_surface_properties}}
• Production intent: {{commercial_output_intent}}

Task

Rewrite the basic draft asset description into an optically accurate commercial generation framework detailing physical shaders, studio lighting schemas, and camera optics.

Method

1. Analyze {{draft_asset_description}} to identify product geometry, foreground focal subjects, and secondary background layers.
2. Translate {{material_surface_properties}} into exact micro-texture, reflectivity, and subsurface scattering descriptors.
3. Construct a three-point optical lighting schema incorporating {{lighting_setup_type}} to accentuate asset contours.
4. Define focal length, aperture values, and depth-of-field falloff using {{camera_lens_specifications}}.
5. Map tonal ranges and color balance directly to {{color_grading_palette}}.
6. Format technical descriptors according to commercial rendering standards tailored to {{commercial_output_intent}}.
7. Assemble the components into an ordered syntax block prioritizing subject physical accuracy over background noise.

Constraints

• MUST translate all abstract quality terms into concrete optical, lighting, or material mechanics.
• MUST NOT use generic marketing terms (e.g., "premium", "luxury", "high-end").
• Keep technical lens parameters physically plausible for the specified camera setup.
• Limit final rewritten prompt to 80 words maximum to maintain high prompt adherence.

Output format

1. Look-Development Parameter Matrix

Structured table outlining Material Shaders, Light Sources, Lens Optics, and Color Gamut.

2. Master Commercial Generation Prompt

Single executable prompt block organized in technical look-dev syntax.

3. Lighting and Shadow Schema Note

Two-sentence specification detailing key light angle, fill ratio, and shadow softness.

Self-review

• Checked that all qualitative marketing adjectives are replaced with optical properties.
• Confirmed lens optics match {{camera_lens_specifications}}.
• Ensured material descriptions accurately represent {{material_surface_properties}}.
