HIGH-GRANULARITY INVENTORY
- Subject(s): 1 young adult man in the foreground (early 20s to early 30s), slim build, light skin tone, short messy dark-brown hair, thin metal-frame round glasses, relaxed smile, side profile facing right. Right hand is raised and holding a smartphone against his cheek as if taking a call. A second subject appears only inside the phone screen: 1 young woman (young adult), medium skin tone, dark blunt bangs with two mini side buns, neutral expression, wearing a bright pink strappy top, taking a mirror selfie with a phone.
- Clothing & materials: Foreground man wears a plain white crew-neck T-shirt (cotton jersey, matte texture, soft folds around shoulder/neck). Woman on screen wears a satin-like or smooth fabric pink top with thin straps.
- Props/objects: 1 black smartphone with metallic edge, held vertically but slightly tilted; screen is on and clearly visible. On-screen selfie includes a phone with triple rear camera module. Background includes out-of-focus urban elements: pale building facade, a parked car, green shrub/tree shapes.
- Environment: Outdoor daytime street or parking-lot edge. Clear blue sky. Bright sun creates crisp highlights on hair, cheek, glasses rim, and fingers. Shallow background separation with mild blur.
- Composition: Tight medium close-up from left-rear quarter angle; man’s head and hand dominate frame. Phone screen is central narrative element and occupies a large readable area near the center-left. Strong “image-inside-image” storytelling. Eye line of foreground subject points forward/right while screen subject faces camera via mirror.
- Lighting: Natural sunlight key from upper right/front-right; minimal fill from ambient sky bounce. Medium-hard shadow edges on hand/neck. Neutral-to-warm skin rendering. Screen emits additional cool-magenta glow on phone glass.
- Color palette: Dominant cool sky blue + neutral skin/beige tones + white shirt; accent hot pink from on-screen outfit. Moderate contrast, clean daylight look.
- Image style: Real photo capture with smartphone aesthetic, high sharpness on foreground skin/hair/hand, slight background blur, no heavy grain, realistic reflections on screen glass and eyeglass lens.
MASTER PROMPT
[Subject] A candid daylight street portrait of a young man in side profile holding a smartphone to his cheek, smiling softly, wearing thin round metal glasses and a plain white T-shirt; his dark tousled hair catches sunlight. The phone screen is clearly visible and shows a young woman with blunt bangs and mini buns taking a mirror selfie in a vivid pink strappy top, holding a triple-camera phone.
[Environment] Outdoor urban setting with a clean blue sky, soft-focus modern building wall, parked car, and green foliage in the background; keep background secondary and out of focus.
[Composition/Camera] Tight medium close-up, camera positioned slightly behind and left of the man, framing his face, hand, and phone as primary elements; emphasize the “screen-within-reality” narrative by keeping the on-screen woman large and readable; natural handheld framing, eye-level perspective.
[Lighting] Bright natural sun as key light from upper right, realistic specular highlights on glasses frame, fingers, and cheekbone, mild shadow under jaw and hand, ambient sky fill, accurate phone screen luminance without clipping.
[Style/Rendering] Photorealistic smartphone photo look, crisp facial detail, realistic skin texture, clean color science, moderate contrast, subtle depth separation, minimal noise.
[Detail constraints] Do not add or remove people, devices, or major objects; keep exactly one real foreground man and one woman only inside the phone screen; preserve phone orientation, side-profile pose, white T-shirt, blue-sky outdoor context, and pink on-screen wardrobe.

extra people in foreground, duplicate faces, warped fingers, deformed hand grip, unreadable phone screen, blank/black screen, mirrored text artifacts, heavy HDR halos, over-smoothing skin, plastic skin, oversaturated neon skin tones, wrong hair color, indoor lighting, night scene, dramatic studio lights, cartoon/anime rendering, CGI look, motion blur, lens dirt, watermark, logo overlays

DELTA PROMPT STRATEGY (Top 10 drift fixes)
1) If the phone screen is unreadable: “make the smartphone display bright and legible, showing a woman in a pink strappy top taking a mirror selfie.”
2) If extra people appear: “keep only one real man in frame and one woman visible only inside the phone screen.”
3) If hand anatomy breaks: “natural right-hand grip with accurate finger joints wrapping the phone edge.”
4) If glasses disappear: “thin round silver wire-frame eyeglasses with subtle sun reflections.”
5) If shirt color changes: “plain white cotton crew-neck T-shirt, no logos, no graphics.”
6) If scene turns indoor: “outdoor daylight with blue sky and soft urban background blur.”
7) If angle is wrong: “left-rear side profile composition, phone pressed near cheek, candid call-like gesture.”
8) If pink accent is weak: “strong hot-pink garment on the woman inside the screen as key accent color.”
9) If lighting is flat: “single bright natural sun key from upper right with crisp highlight edges.”
10) If image looks CGI: “documentary smartphone photo realism, natural skin texture, no 3D render look.”
