生日慶祝畫像

CRITICAL RULE #1 (read first, applies above all else): The face in the 
output MUST be the exact same person as the uploaded reference photo. 
Do not generate a new face, do not beautify, do not idealize, do not 
blend with a generic face. If you are unsure whether the face matches, 
default to making it MORE identical to the reference, not less.

IDENTITY LOCK (exact match required): Match the reference photo exactly 
for: face shape and bone structure, eye shape/size/color/spacing, 
eyebrow shape, nose shape and width, lip shape and fullness, chin and 
jawline shape, cheekbone structure, skin tone and undertone, any 
visible marks, moles, or asymmetries. These are not suggestions — they 
are hard constraints. Zero deviation allowed.

DO NOT COPY FROM REFERENCE (only these things should change): expression, 
eye gaze direction, head angle/tilt, and body pose should NOT match the 
reference photo — generate these freshly based on the scene below. To 
be clear: FACE IDENTITY = locked exactly. EXPRESSION/POSE/ANGLE = freely 
generated and different from the reference.

EMOTIONAL INTENT (design goal): This should feel like a genuine 
milestone birthday moment — the kind of photo a guy would actually 
want for his birthday post, looking like his best real self, 
celebratory and confident, not overly done-up or fantasy-styled.

LIGHTING SETUP (as a real photographer would dial it in): Key light — 
warm string of fairy lights and a soft sunset glow on a rooftop 
terrace, acting as a gentle warm key from camera-left at chest height. 
Fill — soft ambient dusk-blue sky light from above, gently balancing 
the warm key at close to a 2:1 ratio so shadows stay soft. Rim light — 
the fairy lights behind him create a delicate golden edge-glow along 
his hair and shoulder. Catchlights in his eyes should be warm and 
lively, picking up the string lights.

LENS & OPTICS: Simulate an 85mm lens at f/2.0 — flattering facial 
compression, background rendered as soft creamy bokeh with blurred 
balloons, fairy lights, and a city skyline at dusk, gentle fall-off in 
sharpness away from the focal point, faint natural vignette at the 
corners.

FILM/COLOR SCIENCE: Warm celebratory film response — highlights bloom 
softly rather than clipping, shadows lifted gently rather than crushed 
black, warm golden-amber midtones, natural true-to-reference skin 
tone — color grading must not shift his actual skin tone from the 
reference.

Style: A smart-casual outfit (fitted shirt or bomber jacket, sleeves 
slightly rolled), minimal accessories (watch, simple chain) — the 
kind of look he'd actually wear to celebrate, realistic and relatable, 
not an exaggerated glam transformation.

NEW POSE & ANGLE (must differ from reference, face identity unchanged): 
Standing near a balloon arch or fairy-light backdrop, one hand raised 
casually holding a small sparkler or a drink, body angled at three-
quarters to the camera, head turned back over one shoulder toward the 
lens with relaxed energy.

NEW EXPRESSION (must differ from reference, face identity unchanged): 
A genuine, confident laugh or warm open smile with eyes crinkled — 
the natural joy of someone celebrating a happy milestone, right after 
a photographer says "just enjoy the moment and look over at me," not 
a stiff copied expression.

RETOUCH PIPELINE: Smooth tonal transitions while fully preserving fine 
pore-level texture and the reference face's exact proportions. No 
flattening, no waxy skin, no facial reshaping of any kind.

FINAL VERIFICATION (mandatory self-check before output): Compare the 
generated face side-by-side against the reference photo's face shape, 
eyes, nose, lips, and jawline. If any facial feature does not match 
the reference person, discard and regenerate the face to match exactly 
— only the expression, pose, and angle are allowed to differ.
