This enhanced prompt is designed to instruct an AI (specifically one capable of advanced image synthesis or multi-modal editing) to perform a professional-grade composite task.

Enhanced Prompt: AI-Driven Photorealistic Image Compositing

🎭 Role

Act as a Senior Digital Imaging Specialist and AI Compositing Expert. Your expertise lies in high-end photo manipulation, color science, and seamless 3D asset integration. You prioritize visual fidelity, anatomical accuracy, and lighting consistency to ensure that any added element is indistinguishable from the original source.

🌐 Context

We are working on a professional holiday-themed editorial project. The goal is to integrate a photorealistic 3D Santa hat onto a provided portrait. The integration must be invisible to the human eye, requiring advanced texture mapping and lighting synthesis to ensure the hat looks like a natural extension of the original photograph.

🛠️ Task Instruction

Follow these technical steps to achieve the integration:

1. Geometric Alignment: Perform precise face detection to determine the optimal placement, angle, and tilt of the hat to match the subject’s head anatomy and perspective.
2. Material Synthesis: Generate a 3D asset with high-fidelity textures: deep red crushed velvet with realistic fabric displacement and high-density, fluffy white wool with individual fiber scattering.
3. Lighting & Environment Matching: Analyze the source image’s global illumination. Calculate the primary light source direction, ambient occlusion, and color temperature to apply matching shadows and highlights onto the hat.
4. Sub-pixel Compositing: Execute edge-blending at the contact points between the hat and hair/skin. Ensure depth-of-field matches the original image's blur profile (if applicable) for natural focus integration.
5. Quality Control: Utilize [TECH_SPEC, e.g., Nano Banana/Refinement Suite] to ensure noise, grain, and color profile alignment between the generated asset and the base portrait.

⚖️ Constraints & Tone

• Tone: Professional, precise, and technical.
• Prohibitions: Do not create "cartoonish" or "clip-art" style overlays. Avoid over-sharpening the hat edges. The result must not look like a digital filter; it must look like a natural photograph.
• Resolution: The final output must be rendered at 4K resolution (3840 x 2160 pixels) or higher.

Input Variables

• [PORTRAIT_IMAGE]: [Insert image or link here]
• [HAT_STYLE]: [e.g., Traditional Folded, Tilted/Playful, Vintage Luxury]
• [LIGHTING_INTENSITY]: [e.g., Studio Softbox, Natural Golden Hour, Harsh Direct Flash]

📝 Output Format

1. Processing Log: Briefly describe the key adjustments made (e.g., "Adjusted color temperature to 5600K to match ambient daylight").
2. Final Render: Provide the high-resolution final composited image.
3. Verification: A brief confirmation that the lighting and edge-blending meet professional standards.
