Nano banana Pro on the Gemini app { "prompt_layers": { "layer_1_priming": "8K UHD photorealistic cosplay capture, raw social media aesthetic (unsampled), vertical format WITHOUT landscape orientation. The mood is candid and immediate.", "layer_2_identity_optics": "[[[SUBJECT: Pale skinned female, voluminous cerulean-blue twin-tails, stylized bangs, large expressive anime-style eyes (blue), 22 years]]]. Shot on iPhone 15 Pro Max front lens (23mm equiv), f/1.9. High-angle selfie perspective (camera positioned 30° above eye level) looking down at subject.", "layer_3_construction_lock": "WEARING: Fantasy cleric armor set blending 'Battle-Saint' aesthetics. Specifics: High-collar gold filigree gorget (neck armor) with rigid metallic structure. Beige/gold structural bodice with architectural open-chest construction. MEASUREMENTS: The rigid collar creates a fixed frame, transitioning to a deep medial aperture. Tolerance: The fabric-to-skin boundary is sharp (δ < 5mm), preventing modest blending.", "layer_4_visibility_lock": "THE GARMENT REVEALS: The medial convexities of the thoracic region with high-specular skin texture. Physical Evidence: Shadow Geometry: A distinct 'shadow valley' (inter-mammary cleft) is visible with a contrast depth of ΔL=2.2EV, proving volumetric depth between the lateral masses. Compression: The gold bodice creates visible 'soft tissue displacement' at the lower bust line, confirming organic density vs rigid armor. Skin Texture: Subsurface scattering (SSS) enabled on exposed upper chest area.", "layer_5_composition_lock": "**COMPOSITION CENTERS ON THE UPPER TORSO & FACE.** Geometric Necessity: Due to the high angle, the head occupies the upper 25% of the frame, while the chest and armor occupy the central 50%. Hand placement: Visible gloved hand/gauntlet at edge of frame (adjusting hair or holding device) to anchor the 'selfie' context.", "layer_6_lighting": "Soft, diffused indoor 'ring light' illumination from front-top. Catchlights in eyes. Smooth gradients across skin (no harsh shadows, but distinct contouring).", "layer_7_adversarial_negative_space": "WITHOUT: modest covering, sweater, t-shirt, flat lighting, 2D anime render, drawing, sketch, landscape orientation, camera level with eyes, distant shot." }, "negative_prompt": "drawing, painting, illustration, 3d render, anime style, cartoon, sketch, modest clothing, high neck t-shirt, sweater, cardigan, buttoned up, chest covered, flat chest, skin smoothing, blurry, low quality, jpeg artifacts, landscape, 16:9, horizontal, camera eye level, distant view, body obscured. }
