很多朋友留言说,怎么同一个提示词,效果差那么多?
如果你是用Nano Banana, 想要精准控图,就必须要用JSON prompt。(MJ相反,提示词过于复杂并不好)
关于人物“美不美”,这是一个很主观的标准,如果你通过"beautiful","stunning"等形容词来描述,其实不一定有效果
所以尝试给模型一些客观参考,比如让她的五官参考迪丽热巴、杨幂等等明星,效果会要好一些
P1为没有样貌参考,其它为有样貌参考
就用这张真实感拉满的图为例,外貌可以自己微调,咒语如下(包出的):

真人感无敌的一张,仔细看细节
咒语:
A natural grab shot of an alluring day-style woman hiking in the mountains, ponytail with bangs, flushed cheeks from exertion, in a sports bra top and leggings, pausing to look at the view, misty background with slight fog, captured mid-step for dynamic feel.
