手术开始前的外科医生人像

生成一张 4:5 竖版手术开始前的外科医生环境人像。主体是一位 40 岁左右的中国女性外科医生，穿青绿色无标识手术服、一次性手术帽和无字防护面罩，口罩自然垂在下巴下方露出坚定表情，双手正在整理无粉白色无标识无菌手套。场景必须是现代手术室内部，不是诊室：头顶有圆形无影灯形成清晰光环，背景有模糊的手术台轮廓、金属器械托盘和干净的冷蓝白墙面；所有监护仪屏幕仅显示抽象光块，不出现文字、数字或真实界面。构图为半身到七分身，轻微低机位，人物站在画面中央偏左，右侧保留无影灯和器械纵深。光线冷白、青绿、少量银灰高光，干净克制，真实编辑摄影质感，70mm 镜头，浅景深，人物比例真实，不能压扁或拉伸。画面内不要出现任何可读文字、logo、水印、品牌、医院名、药品名、二维码或广告。

Create a 4:5 vertical environmental portrait of a surgeon just before an operation. The subject is a Chinese female surgeon around 40, wearing unbranded teal surgical scrubs, a disposable surgical cap, and a plain protective face shield, with her mask lowered under her chin so her determined expression is visible. She is adjusting powder-free white sterile gloves. The setting must be a modern operating room, not a clinic: a circular surgical lamp forms a clear halo overhead, with a blurred operating table, metal instrument tray, and clean cool blue-white walls in the background. Any monitor screens show only abstract light blocks, with no text, numbers, or real interface. Half-body to three-quarter composition, slight low angle, subject center-left, surgical light and instrument depth on the right. Lighting is cool white and teal with subtle silver highlights, clean and restrained, realistic editorial photography, 70mm lens, shallow depth of field, realistic human proportions without flattening or stretching. No readable text, logo, watermark, brand, hospital name, drug name, QR code, or advertisement anywhere.
