教师职业形象照

生成一张 4:5 竖版教师职业形象照。中国女教师站在明亮小学教室靠窗一侧，手里拿着几盒彩色粉笔和一本无字教案本，身旁有木质讲台、地球仪、绿植和模糊的黑板，黑板上不要出现任何可读文字。她自然侧身回头看向镜头，表情亲切但有专业感。上午自然光，色调为奶白、浅木色、绿色和少量粉笔色，清新不幼稚。真实环境肖像摄影，50mm 镜头，七分身构图，人物比例真实，手部自然。画面内不要出现任何可读文字、logo、水印、学校名称或品牌标识。

Create a 4:5 vertical professional teacher portrait. A Chinese female teacher stands by the windows of a bright elementary classroom, holding several pieces of colored chalk and a blank lesson-plan notebook; beside her are a wooden lectern, globe, plants, and a softly blurred chalkboard with no readable text. She turns naturally toward the camera with a friendly but professional expression. Morning natural light, cream white, pale wood, green, and small chalk-color accents, fresh without feeling childish. Real environmental portrait photography, 50mm lens, three-quarter body composition, realistic proportions and natural hands. No readable text, logo, watermark, school name, or brand mark anywhere in the image.
