一位紅髮女子坐在咖啡館窗邊，若有所思地望向窗外，玻璃上畫著數學公式，營造出知性內省的氛圍

提示詞

A cinematic, photorealistic scene of a thoughtful young woman with wavy auburn hair sitting alone at a wooden café table next to a large glass window. Warm golden sunlight softly illuminates her face as she rests her head on her hand, gazing out the window with a calm, pensive expression. The image is shot from outside the café through the glass, with gentle reflections, light bokeh, and a slightly blurred background creating a dreamy atmosphere.
Handwritten white chalk-style mathematical equations are floating on the window glass around her, as if she is thinking about them: integrals, limits, algebraic formulas, a quadratic graph, trigonometric identities, and E = mc². The equations look lightly sketched, semi-transparent, and artistically placed without blocking her face.
The mood is intellectual, introspective, and peaceful. Shallow depth of field, soft natural lighting, cinematic color grading, warm tones, ultra-high-definition, 4K, highly detailed, realistic photography style, professional lens, soft film grain, gentle glow, modern aesthetic
