AI Prompt for High-Fidelity Athletic Portrait with Physics Control

"[Header] (9:16) Raw high-fidelity photograph, iPhone 17 Pro sensor simulation, high-angle downward perspective, zero bokeh, SHARP focus from the foreground grass textures to the background architecture, f/8 aperture for total structural depth, authentic digital grain. [Subject & Identity Locking] •Identity: Absolute preservation of Image A’s specific facial geometry, emphasizing the almond eye shape, high lip volume, and defined jawline. •Hair Physics: Long, thick braided ponytail composed of dark chocolate textured waves, secured with black technical bands. High-definition follicle detail and hair texture visible where the hair is pulled back under the cap. •Bio-Fidelity: Detailed skin physics (micro-pores, satin-finish hydration). Realistic rendering of the side-profile neck architecture and jawline symmetry. •Expression: Magnetic presence; a self-assured gaze directed upward and slightly off-camera, capturing an authentic post-run athletic aesthetic. [Outfit & Physicality] •Technical Description: High-performance monochromatic athletic-wear. •Upper Geometry: Long-sleeved technical compression-fit half-zip top in matte onyx black. •Lower Geometry: Technical high-cut performance-wear shorts in matte black, showing realistic material-to-skin surface compression. •Accessories: Black technical baseball cap with a white "NY" logo; white technical wireless earbuds (AirPods style); white technical smartwatch on the left wrist. •Physicality: Athletic proximal limb geometry; symmetrical quadricep definition emphasized by the crouching pose. [Pose & Composition] •Geometry: High-angle downward "squat" selfie. The subject is in a full crouch on a grass surface, right arm extended toward the lens to capture the shot. •Framing: Vertical 9:16 orientation. The composition uses the wide-angle perspective to include the subject’s body and the surrounding environment. •Anatomy: Realistic knee-joint flexion and calf-to-thigh compression. The extended selfie arm must show natural muscle-to-skin interaction and shoulder-joint displacement. [Environment & Lighting] •Atmosphere: Public park or suburban residential green space. •Background Integrity: A red-toned technical-surface running track curving into the distance. Background features bare deciduous trees and white multi-story modern residential buildings. The grass in the foreground is lush green with scattered brown autumn leaves. •Lighting: Neutral diffused 5500K daylight. The light source provides consistent illumination across the skin and black textiles, creating soft shadows that define the subject’s anatomical contours. [Failure Prevention Rule] •Command: Use "Technical compression-fit athletic top" and "High-cut performance-wear shorts" to ensure the AI maintains the exact fit and length. •Constraint: Explicitly command "Zero artificial bokeh" to ensure the distant apartment buildings and the red track remain perfectly crisp. Specify "Anatomical thigh symmetry" to ensure t"
