STRICT 1:1 FACE & IDENTITY PRESERVATION — NON-NEGOTIABLE.
Use Reference Image 1 exclusively for the adult man's identity and Reference Image 2 exclusively for the adult woman's identity. Preserve both faces, facial proportions, eye shape, nose, lips, skin tone and individual identity exactly. The man's facial hair, hair color, hair texture, hairstyle, tattoos and piercings must come exclusively from his uploaded reference. The woman's hair color, hair texture, hairstyle, tattoos, piercings and facial characteristics must come exclusively from her uploaded reference. Never copy the original inspiration subjects' identities or tattoos.
MAN — FOREGROUND:
The man stands in the foreground, facing the mirror with his arms crossed firmly over his chest. He wears a fitted white ribbed tank top, a chunky silver chain necklace, a matching silver bracelet and dark trousers. His shoulders are squared and his posture is confident. He makes a playful, slightly exaggerated grimace toward the mirror, narrowing one eye and pressing his lips together. His build should remain consistent with his uploaded reference rather than being artificially enlarged. Preserve his authentic tattoos wherever visible.
WOMAN — BACKGROUND:
The woman stands directly behind him, slightly offset to one side, wearing an elegant black blazer over a dark low-cut top. Her hair falls naturally over her shoulders according to her uploaded reference. She holds a compact silver digital camera at face height, taking a mirror photograph of both of them. Her expression is confident and composed, with a subtle smile. Her position allows her face and upper body to remain clearly visible behind the man's shoulder.
LOCATION:
A gritty industrial changing room or warehouse washroom with aged green-painted walls, a large mirror, visible wall-mounted safety notices, an open doorway and daylight entering from the side. The environment should look authentic and slightly worn, with realistic surface imperfections and no polished studio finish.
COMPOSITION:
Vertical waist-up mirror portrait. The man dominates the foreground, while the woman appears clearly behind his shoulder. His crossed arms and silver chain form strong visual lines; her camera and dark outfit balance the composition. Maintain realistic mirror geometry and correct reflections.
LIGHTING & CAMERA:
Soft daylight mixed with muted industrial ambient light, restrained contrast and a subtle film-grain texture. Canon EOS R5, full-frame DSLR, 85mm lens, f/1.8, RAW photo style, HDR, realistic skin pores, detailed fabric and metal reflections, ultra-photorealistic 4K, vertical 2:3 composition.
NEGATIVE CONSTRAINTS:
No identity blending, no invented tattoos, no altered hair color, no changed facial features, no exaggerated muscles, no extra arms or fingers, no duplicated camera, no incorrect mirror reflections, no plastic skin, no CGI, no fake text on safety signs, no watermark.
