Father and Son Outdoor Portrait

Create a 4:5 vertical outdoor father-and-son portrait. A Chinese father and his roughly eight-year-old son repair a child’s bicycle beside a tree-lined park path; the father crouches while holding the handlebar, and the son hands him a tool while watching carefully. Soft afternoon backlight filters through leaves, with green grass and a light gray walkway as a clean background. Real documentary photography, 35mm environmental portrait, full bodies and bicycle visible, realistic proportions with no compression or distortion. No readable text, logo, watermark, license plate, or brand mark anywhere in the image.

生成一张 4:5 竖版父子户外写真。中国父亲和八岁左右儿子在林荫公园小路旁一起修理儿童自行车，父亲半蹲扶着车把，儿子递工具并认真观察，两人有真实互动。下午柔和逆光穿过树叶，绿色草地和浅灰步道形成清爽背景，色调自然明亮但不过度发黄。真实纪实摄影，35mm 环境人像，保留人物全身和自行车，身体比例真实不压扁。画面内不要出现任何可读文字、logo、水印、车牌或品牌标识。
