カップルのポートレート — 重要なルールを読む

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

IDENTITY LOCK (exact match required for both subjects): Match the
reference photo exactly for each person: 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 for either person.

DO NOT COPY FROM REFERENCE (only these things should change): both
subjects' expressions, eye gaze directions, head angles/tilts, and
body poses should NOT match the reference photo — generate these
freshly based on the scene below. To be clear: FACE IDENTITY (both
people) = locked exactly. EXPRESSION/POSE/ANGLE (both people) = freely
generated and different from the reference.

EMOTIONAL INTENT (design goal): This should feel like a genuine, warm
"Sunday morning together" domestic moment — the kind of photo a couple
would want to remember cooking breakfast together at home. Playful,
comfortable, real chemistry, not a staged glamour shoot. Both partners
must look equally flattering — neither should outshine the other.

LIGHTING SETUP (as a real photographer would dial it in): Key light —
soft morning sunlight streaming through a kitchen window, acting as a
warm natural key from camera-left, gently diffused by sheer curtains.
Fill — soft ambient light bounced from light-colored kitchen counters,
gently lifting shadows at roughly a 2:1 ratio. Rim light — window
light grazes both subjects' hair and shoulder edges from behind,
creating a soft golden-white rim. Catchlights in both sets of eyes
should be bright and warm.

LENS & OPTICS: Simulate an 85mm lens at f/2.0 — flattering facial
compression, background rendered as soft creamy bokeh with a blurred
cozy kitchen (open shelves, hanging plants, a steaming pan), gentle
fall-off in sharpness away from the focal point, faint natural
vignette at the corners.

FILM/COLOR SCIENCE: Warm domestic-morning film response — window-light
highlights bloom softly rather than clipping, shadows lifted gently
rather than crushed black, natural warm-neutral midtones, true-to-
reference skin tones for both.

Style: Cozy, wearable casual outfits — soft oversized tees, an apron
tied over one partner's outfit — realistic and relatable, not an
exaggerated glam transformation for either person.

COUPLE BIOMECHANICS & NEW POSE (must differ from reference photo):
Standing together at the kitchen counter, one partner behind the
other with arms loosely wrapped around their waist while they stir
something in a bowl, the other partner leaning back slightly into
them, flour or a light dusting of ingredients playfully visible on the
counter, natural weight shift with both bodies settled comfortably
together.

NEW EXPRESSION (must differ from reference, face identity unchanged
for both): Genuine playful joy — a shared laugh mid-conversation, one
partner glancing at the other with a warm smile, unguarded and
spontaneous, not composed or stiff expressions.

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

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 — a genuinely caught moment, not a staged shot.

FINAL VERIFICATION (mandatory self-check before output): Compare each
generated face side-by-side against its corresponding reference photo
face shape, eyes, nose, lips, and jawline. If either person's facial
features do not match their reference, discard and regenerate that
face to match exactly — only expression, pose, and angle are allowed
to differ for both. Also confirm correct hand anatomy for both,
especially around the bowl/utensils.
