json Gemini Nano Banana 3.0 Prompt: { "image_request": { "style": { "overall_theme": "dark, dramatic, mysterious", "quality": "hyperrealistic", "resolution": "8K", "focus": "ultra-detailed", "visual_tone": "high contrast with deep shadows and targeted lighting", "mood": "introspective, quiet, and enigmatic" }, "character": { "type": "female", "pose": { "description": "The character is standing in a serene yet intriguing pose. One hand is gently touching the lips, as if in a thoughtful gesture, while the other hand remains relaxed or out of view. The eyes are directly gazing at the viewer, with a mysterious, quiet expression. The face should exude subtle emotion — neither too bright nor too dark, with a sense of depth and contemplation." }, "facial_features": { "expression": "mysterious, quiet, introspective", "eyes": { "gaze": "directly at the viewer", "intensity": "gentle yet piercing" }, "lips": { "gesture": "hand resting lightly on the lips, suggesting contemplation" }, "skin": { "texture": "realistic human skin with visible pores, subtle imperfections, fine lines, and micro-details. Avoid any anime-style smoothing or stylized rendering. The skin should have natural subsurface scattering to create realistic light interaction." }, "shading": { "depth": "natural shadows and highlights on the face, shaped by the lighting", "highlights": "subtle skin highlights on the forehead, cheeks, and nose bridge", "shadows": "soft, but with high contrast along the jawline and under the chin" } } }, "hair": { "length": "long, flowing, with loose, natural strands that vary in shape and thickness", "texture": "detailed and natural, with visible strands and natural movement. The hair catches the diagonal light, illuminating individual strands and creating a sense of depth and texture.", "lighting_interaction": { "light": "angled beam of light from the top-left, creating scattered highlights across the hair. Some strands should glow brightly under the light, while others fade into shadows. The light\'s interaction with the hair should create an almost ethereal, dynamic effect with highlights and irregular shadows." }, "shadow_play": "The light passing through the hair should cast broken, irregular shadow patterns onto the face, particularly along the cheekbones and jawline." }, "lighting": { "type": "angled spotlight", "position": "top-left", "direction": "diagonal beam moving toward the lower-right", "intensity": "moderate to high", "focus": "The beam should first illuminate the hair, creating scattered highlights that gradually transition to shadows on the face and body.", "falloff": "high falloff beyond the beam, causing everything outside the direct light to fade into deep shadow.", "light_quality": "soft yet focused, with irregular patterns formed by hair strands catching the light. No harsh horizontal light bands, maintaining a diagonal flow." }, "background": { "color": "completely black", "effect": "The background should be pure black, allowing the character to stand out dramatically. The absence of additional details or elements in the background ensures the focus remains on the character, lighting, and shadows." }, "clothing": { "top": { "description": "The character wears a sweater, which should blend almost fully into the surrounding shadows due to the high falloff of the lighting. The texture and details of the sweater should be subtly implied but not fully visible. The shadows and lighting should make it hard to distinguish the sweater from the dark background." } } }
