提示词枢纽

Nano Banana 提示词指南

先说清要生成什么,再写需要保留与修改的部分。本页提供提示词组织方法、可复制框架与任务教程入口;按场景找成套示例可阅读提示词合集。本站是独立教程站,实际生成在应用中完成,模型、额度与收费以所用应用显示为准。

如何写出更好的 Nano Banana 提示词

从「主体 + 动作 + 场景」开始,再补充构图、光照和用途。编辑参考图时,把修改范围与保留要求分开写,例如「仅替换背景,保留产品轮廓、标签位置和颜色」,避免同时要求重设计与完全保真。

提示词是约束说明,不是效果保证。人物、包装和文字都需要对照原图检查;是否改用 Pro,应根据应用可用模型和实际结果决定,不能用一句“身份锁定”保证五官不变。

  • 先写主体 + 动作 + 场景
  • 明确人脸、Logo、产品外形的保留约束
  • 描述画幅用途,并在应用中核对实际比例与尺寸
  • 用短指令迭代,而不是整段重写

本枢纽包含什么

下方提供可复制框架与封面、电商、海报等教程入口。先选择与你的输入相符的任务:纯文字生成需要描述主体与场景,参考图编辑需要明确修改范围,多图任务需要说明每张图分别提供什么信息。

从模糊要求改成可检查的指令

模糊写法:「让产品更高级」。可检查写法:「以参考图中的产品为主体,仅将背景替换为浅灰影棚,主光从左上方照射,保留瓶身形状、标签与颜色,画面右侧留出排版空间」。这是写法示例,不是已完成的生成测试。

得到第一版后,每次只修正一个问题,例如「保持主体与构图,只减弱背景阴影」。若新结果持续偏离参考图,回到原始输入缩小修改范围;文字反复出错时,可生成无字底图后再排版。

提示词攻略列表

常见问题

提示词指南应该从哪篇开始?

先复制本页可复制模板,再看通用 AI 图像提示词指南,然后打开与你任务匹配的工作流(缩略图、电商、海报或局部编辑)。

这些提示词 Nano Banana 和 Pro 都能用吗?

可以作为描述任务的起点,但不同模型与应用支持的输入、设置可能不同。先确认参考图是否实际上传、模型是否可用,再检查结果;同一段提示词不保证在不同模型中得到相同效果。

这些模板可以免费复制吗?

本页模板可以直接复制。先替换占位符,再在应用中生成。复制模板免费不代表生成图片免费,额度和收费请查看应用当前说明。

要把标题直接画进图里吗?

不建议。请留出安静排版区,在后期加字。AI 内嵌文字容易乱码,海报和缩略图尤其明显。

本站与生图应用有什么区别?

本站提供独立指南、模板和教程入口;按钮跳转到合作生图应用。本站与合作应用均不代表 Google 官方服务,应用账号、可用模型与付费条件需在应用内确认。

在哪里看定价?

可从套餐与定价页了解说明,购买前以实际生图应用的计费页面为准。不要仅依据教程判断免费额度、模型开放情况或套餐权益。
