AI 图像编辑提示词参考之：背景替换

在 AI 图像编辑中（以 Flux Kontext 为例），“替换背景”（Background Replacement）是提升图像表现力的关键手段之一。但背景更换不仅仅是简单的视觉置换，更重要的是：确保人物主体外观不变，并与新背景在色温、色调、光影等方面自然融合。只有这样，最终图像才会呈现出“原本拍摄于该背景环境”的真实感。

建议使用以下结构组织提示词：

Replace the background with [新背景] while keeping [不变内容] unchanged and matching lighting and color with the new environment.

将背景更换为 ……，同时保持 …… 不变，并使光线与色调与新环境协调一致。
