High-Fidelity Flash Selfie Portrait Prompt

An extremely detailed, technical prompt designed to generate a raw, high-fidelity portrait simulating an iPhone 17 Pro flash photograph. It uses 'Identity Lock' and 'Expression Sync' to ensure precise replication of facial features and expression from external references (A and B, which are implied), focusing heavily on epidermal physics, lighting (hard flash), and anatomical volume.

Prompt

(9:16). Raw high-fidelity photograph, iPhone 17 Pro simulation, 35mm portrait focal length, f/1.8 aperture for shallow depth of field, authentic digital grain and high-contrast front-facing flash photography aesthetics.

Identity Lock: Absolute inheritance of facial geometry coordinates from Image A. Almond-shaped eyes with extreme volumetric lash density, specific lip symmetry with high-gloss hydration, and the distinct pigmented mole located at the right nasolabial coordinate. Hair is raven-black, straight, shoulder-length with a sharp center part and natural movement.
Bio-Fidelity: Epidermal physics featuring visible micro-pores, fine vellus hair along the jawline, and high-intensity specular highlights on the forehead and cheeks from the flash source.
Expression Sync: Expression Lock—replicate the direct-to-lens gaze, 15-degree head tilt, and relaxed neutral pout with emphasized philtrum geometry from Image B.

Outfit & Physicality:

Technical Description: Strapless technical compression-fit tube top in matte obsidian black, featuring a scalloped floral lace-trim overlay at the upper hem.
Textile Architecture: High-tensile fabric-to-skin tension; visible lace weave patterns and elasticized structural seaming.
Anatomical Volume: Hyper-defined silhouette with maximum anatomical emphasis on the décolletage and bust geometry; apply the 20% over-description for natural anatomical ratio definition.
Accessories: 1mm silver micro-link chain with a centered teardrop-shaped crystal pendant.
Pose & Interaction:

Geometry: Medium-close portrait perspective; torso angled slightly away while the head turns toward the lens; prominent collarbone (clavicle) and shoulder-joint definition.
Articulation: Natural shoulder elevation to frame the face; realistic skin-texture transitions at the underarm and neck.
Environment & Lighting:

Atmosphere: Dimly lit domestic bedroom environment; dominated by a powerful, hard-light front-facing flash creating sharp contrast.
Background Integrity: Pixel-perfect inventory of a white-on-white textured duvet with organic fabric folds, a dark-stained wood-grain headboard, and neutral-toned wall surfaces.
Shadow Ray-Tracing: Hard-edged drop shadow cast directly behind the subject onto the background; deep ambient occlusion in the folds of the black garment.
