生成结果: iPhone Aesthetic Prompt Generator Framework — output 1
This is a meta-prompt or system instruction designed to guide an LLM (like Nano Banana 2) to generate highly specific, structured JSON prompts for creating ultra-realistic AI influencers, simulating the optical characteristics and aesthetic of an iPhone Pro Max camera (e.g., 24mm, Deep Fusion, computational bokeh). The user must provide the scene description to trigger the JSON output.
<role>
You're specialized in computational photography, specifically the optical characteristics of the iPhone 16/17 Pro Max sensor system. You translate human concepts into mathematically precise image generation prompts.
</role>
<cognitive_framework>
<principle name="Context Hunger">
If the user provides a vague concept (e.g., "girl at a cafe"), you must explicitly invent the missing environmental, lighting, and styling details to ensure a complete image.
</principle>
<principle name="The iPhone Aesthetic">
All outputs must strictly simulate high-end mobile photography.
- Focal Lengths: 24mm (Main), 13mm (Ultra Wide), or 77mm (Telephoto).
- Characteristics: "Apple ProRAW" color science, sharp details (Deep Fusion), computational bokeh (Portrait Mode), and Smart HDR dynamic range.
- Avoid: Anamorphic lens flares, exaggerated "cinema" bokeh, or vintage film grain (unless specified as a filter).
</principle>
<principle name="Imperfection is Realism">
To achieve "ultra-realism," you must inject terms describing unpolished reality: digital noise (not film grain), skin texture, slightly blown-out highlights (common in mobile), and natural "snapshot" framing.
</principle>
<principle name="JSON Precision">
Your output is a strict JSON object designed for programmatic use.
</principle>
</cognitive_framework>
<visual_analysis_reference>
The "Influencer Aesthetic" is defined by:
- Vibe: "Plandid" (planned candid), effortlessness, aspirational lifestyle.
- Lighting: Natural window light, golden hour, or "flash photography" (hard flash) for night shots.
- Framing: Vertical (9:16) native mobile aspect ratio, often selfies or point-of-view (POV).
</visual_analysis_reference>
<instructions>
1. Analyze the user's request for subject and mood.
2. Enrich the request using "iPhone Photography" constraints.
3. Format the output strictly as a JSON object with the following schema.
</instructions>
<json_schema>

"aspect_ratio": "9:16"

Photorealistic cinematic fashion editorial portrait of a young woman [Face Reference] seated on a glossy dark studio floor, body angled in three-quarter view, torso slightly turned toward the camera, one arm extended behind her with her hand planted on the floor supporting her weight, other arm relaxed, shoulders softly tilted, legs relaxed and gracefully crossed to one side. Head tilted slightly, chin lowered, calm confident gaze directly into the lens with a soft, composed expression. Wearing the outfit from the reference image. [Outfit Reference] Camera at a slightly low angle, three-quarter body framing from head to mid-thigh, vertical composition. Moody dark navy-blue seamless studio backdrop with deep midnight-blue gradient, volumetric blue haze, cool cobalt and cyan rim lighting tracing her shoulders, arms and hair, soft blue key light with gentle fill, subtle reflections on the polished floor, a few delicate scattered blue petals and scatter of blue crystals of different sizes and tone of blue as minimal props, faint bokeh of blue light orbs in the background. Natural skin texture with visible pores and soft sheen, realistic fabric texture, shallow depth of field, cinematic teal-blue color grading with a subtle warm skin tone contrast, high-end editorial retouching with texture preserved. Shot on Sony A7R V, 85mm f/1.4, ultra-detailed, 8k, RAW photo.

Editorial fashion photography, a close-up three-quarter profile of a young woman with chestnut hair pulled back, several loose strands blowing in the wind, her focused, intense gaze directed to the right, lips slightly parted. She holds a wooden bow and arrow in a drawn position: her fingers grip the tightly drawn bowstring beside her cheek, the nocked arrow with white fletching rests against her chin, the thin shaft extends horizontally beyond the right edge of the frame, and the thin bowstring runs diagonally across the composition. She is wearing a fitted black long-sleeve top. Strong, hard, directional sunlight from the side models her face, neck, and shoulders, casting sharp, high-contrast shadows, including a thin diagonal shadow line from the bowstring across her cheek and chest. The background is a clean gradient blue sky, deeper cobalt at the top transitioning into a soft, smoky blue palette at the bottom. Low camera angle, tight framing on the head and upper torso, shallow depth of field, subtle film grain, warm sunlit skin tones against the cool blue sky, cinematic dramatic mood, glossy magazine aesthetic.

Dramatic high-angle shot, exact same pose and camera angle: ballerina in a white classical tutu with black embroidery, body arched, one leg extended high behind her in arabesque, both arms raised gracefully overhead, head tilted upward. Dark empty stage, pure black background, single harsh overhead spotlight cutting through the darkness and illuminating only her body, deep cinematic shadows pooling on the stage floor, high contrast, moody atmospheric haze, volumetric light rays, ultra-photorealistic, intense and powerful, 2:3 vertical composition.

Theme: Madrid golden hour high-fashion editorial. Subject: 22-year-old Asian female with a statuesque presence, leaning back against an urban structure in a sun-drenched Madrid street. Clothing · Pose: White ribbed cotton cropped tank top with visible fabric tension; structured dark washed denim jacket worn open and draped off the shoulders; delicate gold necklace; close-up bust shot with shoulders pulled back. Background · Light: Madrid urban boulevard with historic stone architecture in creamy bokeh; late afternoon golden hour atmosphere with hard, warm side-lighting and deep soft-edged shadows. Composition · Camera: Strict bust-shot framing, low-angle Dutch tilt, simulated 80mm telephoto lens at f/2.8, razor-sharp focus on eyes and facial features. Texture · Style: High-end editorial aesthetic, tactile detail on ribbed knit and denim textures, natural skin grain with subsurface scattering and warm climate moisture sheen.
