灵感还没有完全成形时,先做出一张图,往往能让讨论更具体。Nano Banana 2 是 Gemini 3.1 Flash Image 的常用名称,兼顾生成效率与图像理解,既能按文字创作,也能围绕参考图继续编辑,适合日常内容生产与反复试方案。
你可以先描述人物、商品或场景,再补充画幅、光线和视觉重点。比如为一本新书制作社交封面,可以让书本成为画面中心,用桌面与窗光营造阅读气氛,再预留放标题的位置。模型也能处理图片里的文字,但明确的短文案与清楚的版式要求,比泛泛要求“设计得漂亮”更容易获得可用结果。
参考图编辑让修改不必每次从头开始。可以保留人物、商品或已有构图,尝试新的背景与配色;也可以让不同参考图分别提供主体和风格。做系列视觉时,持续使用同一张主体参考,明确哪些地方不能变,再分步调整环境,能更容易延续整体感觉。
模型家族提供从较低分辨率到 4K 的创作选择,适合从草图比较推进到较清晰的展示素材。它尤其适合封面、活动配图、商品场景和轻量设计提案。生成后的文字、人物细节与产品形状仍需要检查;已经满意的图片,下一轮尽量只改一个重点,避免越改越偏离原来的方向。
图一是书封面,请保留书名、封面颜色和书本比例。把书放在窗边木桌上,旁边只有一杯清茶。午后柔光,温暖但不过度泛黄;正方形构图,书本位于右下方,左上角留白,不增加新文字。
接着可要求“只把场景换成简洁书架前,书本角度和大小不变”,比较两种发布风格。
有参考图还需要很长的描述吗? 重点说明保留的主体,以及新的场景、布局和氛围即可。
怎么避免每次修改都换一张脸或一个商品? 使用清晰、统一的主体参考,并限制每轮改动范围;重要细节依然需要核查。
适合做精确排版吗? 可以先完成图文方向,最终文字和对齐仍建议人工检查。
