把遠景換成利雅得天際線
只動最遠那層背景，換成利雅得地標群，光影鏡頭顆粒全部不許動。
✍️ 好的換背景指令分兩半：一半說換什麼，另一半列清單說什麼不許動。這裡“比例要和前景位置對得上”是最容易漏的一句，漏了天際線就會像貼紙。“保留”清單可以整段搬去別的編輯任務。
📋 提示詞 自然語言
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.
📋 中文譯寫版 自然語言
只把最遠處的背景替換成沙烏地阿拉伯利雅得的城市天際線，儘量多地畫出標誌性建築。新天際線要與前景主體所處位置保持真實比例，並處理成柔和的繪畫感虛化散景，與原圖裡已有的城市處理方式一致。其餘全部保持原樣：光照、取景、機位角度、鏡頭、顆粒、整體美學、色彩分級與氛圍。
