A static close-up portrait shot of a young woman in soft daylight. She looks directly at the camera with a calm, innocent expression. Very subtle natural movement only: gentle breathing, tiny eyelid motion, minimal hair movement, a soft sweet smile gradually appearing. Timeline: 0–3 seconds: completely normal portrait, natural stillness, soft eye contact. 3–5 seconds: in one eye only, a faint dark shape begins to form inside the iris. 5–7 seconds: the shape resolves into a second pupil, small and perfectly defined, sitting beside the original pupil in the same iris. 7–8 seconds: the second pupil becomes fully visible while her expression remains gentle and serene. The effect should be elegant, realistic, and uncanny, not grotesque. Keep the face stable, beautiful, and symmetrical, with only the intended eye transformation changing. Photorealistic skin, realistic iris detail, no camera movement, no background changes.
