冬天雪幕街編輯情侣肖像".

Edit this photo. Keep both subjects' exact facial bone structure, eye 
shape and color, nose shape, lip shape, jawline, and skin tone 100% 
identical to the original photo. Body build and proportions unchanged 
for both individuals. Non-negotiable.

LIGHTING SETUP (as a real photographer would dial it in): Key light — 
soft overcast winter daylight acting as a giant natural softbox from 
above, even and diffused, slightly cool in tone. Fill — warm light 
spilling from a nearby shopfront window, gently lifting shadows on 
the side facing the street with a soft amber tint. Rim light — a 
streetlamp behind them casts a faint warm halo along both subjects' 
hair and shoulder edges. Catchlights in both sets of eyes should be 
soft and diffused, reflecting the pale winter sky.

LENS & OPTICS: Simulate an 85mm lens at f/2.0 — flattering facial 
compression, background rendered as soft creamy bokeh with falling 
snowflakes turned into soft glowing specks, gentle fall-off in 
sharpness away from the focal point, faint natural vignette at the 
corners.

FILM/COLOR SCIENCE: Emulate a cool-warm winter film response — 
highlights on the snow softly bloom rather than clipping, shadows 
lifted with a faint cool-blue tint rather than crushed black, warm 
skin midtones held steady against the cooler snowy background for 
natural depth separation.

COUPLE BIOMECHANICS (real physical interlock, not a generic pose): 
Standing close together on a quiet snowy street, one partner's arm 
wrapped around the other's shoulder pulling them in against the cold, 
free hands tucked into coat pockets or loosely clasped between them 
with natural finger overlap. Heads tilted slightly toward each other, 
weight leaning inward as two real bodies naturally would for warmth — 
not two independently balanced figures.

EXPRESSION: Warm and unguarded despite the cold — a genuine shared 
laugh with visible breath in the cold air, eyes slightly crinkled, 
noses and cheeks softly flushed pink from the chill, shoulders 
hunched slightly inward together.

RETOUCH PIPELINE: Frequency-separation-style retouching — smooth 
tonal transitions on skin while fully preserving fine pore-level 
texture and natural color variation under the mixed cool/warm 
lighting. Subtle dodge-and-burn to retain natural facial planes for 
both subjects, no flattened or washed-out glow.

FINISHING: Fine film grain overlay at low opacity, very slight 
chromatic softness at the frame edges as a real lens would render, no 
digital sharpening halos, natural imperfect crop as if not perfectly 
composed in-camera.

Ensure zero facial distortion, anatomically correct hands with 
natural finger overlap between both subjects, and consistent shadow/
light-source logic between the cool overcast key and warm shopfront 
fill.
