在 Flux Kontext 图像编辑工作流中,“基础修改”(Basic Modifications)是最常用也最容易上手的功能之一。它允许用户通过自然语言提示词对图像中的颜色、光线、天气、姿势、表情等内容进行局部调整,并通过附加提示控制哪些部分保持不变,以获得精准、可控的修改效果。
Flux Kontext 支持自然语言理解,但建议尽量使用结构明确的指令:
Change / Convert / Replace / Make / Add + [修改对象] + to / into / with / more / less ..., while keeping [不变部分] unchanged常用动词结构:
Change ... to ...
改变 …… 为 ……
Make ... more ...

可附加限制用语:
