Day and Night Split Portrait

A photorealistic portrait of [a young woman], with her face sharply split vertically down the center of her nose, contrasting day and night. The LEFT HALF is lit by warm, golden afternoon sunlight (3200K), featuring sun-kissed skin, warm highlights in her hair, reflections of sun and clouds in her eye, and [a white linen shirt] on her shoulder; behind her is a bright blue sky, [a sunflower, green leaves, and a butterfly] near her ear. The RIGHT HALF is lit by cool, blue moonlight (7000K), featuring a silvery, cool complexion, cool highlights in her hair, reflections of moonlight and stars in her eye, and [a dark velvet dress] on her shoulder; behind her is a dark night sky with stars, [a crescent moon, glowing fireflies, and a moth] near her ear. A calm, direct gaze with the exact same expression on both sides, with a sharp vertical division along the bridge of the nose and zero light bleed between halves. Shot on an 85mm f/1.8 lens, eye-level head-and-shoulders close-up portrait, shallow depth of field.
