追拍骑手背景糊了人没糊

A dynamic frame built around motion: a photographer pans to track a fast-moving cyclist, running a high-speed camera so the background smears into motion blur while the subject stays razor sharp. Set on an urban street at golden hour, the low light rakes across the scene to sell both speed and clarity. Cinematic framing, ultra-detailed, rendered at high definition.

整张图围绕"运动感"搭建：摄影师追拍一位飞驰的骑手，用高速相机让背景拖成运动模糊，主体却依然锐利清晰。场景设在城市街道的黄金时段，低角度的光线同时衬出速度感和清晰度。电影感构图，超精细，高清渲染。
