图书馆学者人像

生成一张 4:5 竖版图书馆学者人像。中国中年女性学者坐在大型公共图书馆阅览桌旁，穿深灰羊毛开衫和白色衬衫，低头查看一张完全空白的手稿纸，旁边叠放几本无字封面书和一副眼镜。背景是高挑阅览大厅、无文字书脊色块、绿色台灯和远处读者虚影，不是站在书架间。构图为半身环境肖像，桌面前景清楚，人物位于画面右侧，左侧留出大厅纵深。光线为绿色台灯暖光加天窗冷柔光，色调深灰、墨绿、暖木、纸白。真实纪实摄影，50mm 镜头，人物比例真实。画面内不要出现任何可读文字、logo、水印、书名、馆名、标签或屏幕内容。

Create a 4:5 vertical library scholar portrait. A middle-aged Chinese female scholar sits at a reading table inside a large public library, wearing a dark gray wool cardigan and white shirt. She looks down at a completely blank manuscript page, with several no-text cover books and a pair of glasses nearby. The background contains a tall reading hall, no-text book-spine color blocks, green banker lamps, and blurred distant readers; she is not standing among shelves. Half-body environmental portrait, clear table foreground, subject on the right side, library hall depth left in the frame. Lighting from warm green desk lamps plus cool soft skylight; palette of dark gray, ink green, warm wood, and paper white. Real documentary photography, 50mm lens, realistic proportions. No readable text, logo, watermark, book title, library name, label, or screen content anywhere.
