把远景换成利雅得天际线
只动最远那层背景，换成利雅得地标群，光影镜头颗粒全部不许动。
✍️ 好的换背景指令分两半：一半说换什么，另一半列清单说什么不许动。这里“比例要和前景位置对得上”是最容易漏的一句，漏了天际线就会像贴纸。“保留”清单可以整段搬去别的编辑任务。
📋 提示词 自然语言
Swap only the far background for the Riyadh skyline in Saudi Arabia, showing as many of its landmark towers as you can. The new skyline has to keep true-to-life proportions relative to where the foreground subjects stand, and it should be rendered as soft, painterly bokeh so it matches the city treatment already in the original image. Leave everything else as it was: lighting, framing, camera angle, lens, grain, overall aesthetic, colour grading and mood.

只把最远处的背景替换成沙特阿拉伯利雅得的城市天际线，尽量多地画出标志性建筑。新天际线要与前景主体所处位置保持真实比例，并处理成柔和的绘画感虚化散景，与原图里已有的城市处理方式一致。其余全部保持原样：光照、取景、机位角度、镜头、颗粒、整体美学、色彩分级与氛围。
