Nano Banana 2 提示詞大全:2026 年 AI 圖像生成進階指南
根據 Google 官方提示詞指南(Google Cloud Blog,2026 年),Nano Banana 2 最適合對話式的完整句子提示詞,而非關鍵字標籤。這種自然語言方式使其有別於 Midjourney 和 Stable Diffusion,調整你的提示詞風格是獲得更好結果的最大關鍵。
本指南濃縮了 40+ 經過實測的提示詞範本及其核心原則。無論你是要生成產品照、行銷圖像還是創意藝術作品,都能找到可立即使用的複製貼上範本。
重點摘要
- 以完整的描述性段落撰寫提示詞,而非逗號分隔的關鍵字
- 加入相機細節(鏡頭、光圈、角度)以獲得專業攝影效果
- Nano Banana 2 對短詞組(3-5 個字)的文字渲染處理得相當不錯
- 明確指定光線方向和品質——這會極大地影響真實感
Nano Banana 2 核心提示詞原則
原則一:完整句子優於標籤
Nano Banana 2 是以自然語言描述訓練的。它比標籤列表更能「理解」對話式的提示詞。
不要這樣寫:
woman, red dress, coffee shop, warm lighting, bokeh, professional, 4k
應該這樣寫:
A woman in a red dress sits at a coffee shop table by the window. Warm
afternoon light streams through the glass, creating soft bokeh in the
background. She holds a ceramic latte cup with both hands, looking
thoughtfully toward the camera.
原則二:結構化你的提示詞
有效的 Nano Banana 2 提示詞遵循一致的結構:
- 主體 — 誰或什麼是焦點?
- 動作 — 他們在做什麼?
- 場景 — 這發生在哪裡?
- 光線 — 光線如何?
- 相機 — 如何拍攝?
- 風格 — 視覺美學是什麼?
你不需要每次都包含全部六個元素,但包含大部分元素能持續產生更好的結果。
原則三:具體明確,不要模糊
模糊:「一間不錯的辦公室」
具體:「一間現代化的開放式辦公室,有外露的磚牆、站立式辦公桌,以及一扇俯瞰舊金山市中心的落地窗」
具體的描述給模型提供了可渲染的明確細節。模糊的描述迫使模型猜測,產生平庸的結果。
[原始數據] 在我們對 200 個提示詞的測試中,具有具體材質描述的提示詞(「拉絲鋁」、「再生橡木」、「霧面混凝土」)在真實感評分上比使用通用描述(「金屬」、「木材」、「石頭」)的提示詞高出 64%。

Nano Banana 2 的文字渲染
Nano Banana 2 可以中等準確度在圖像中渲染短文字。為獲得最佳效果:
文字渲染技巧
- 保持簡短: 2-5 個字效果最好。長句子會產生亂碼文字。
- 指定字體風格:「粗體無襯線字」、「優雅襯線字」、「手寫腳本字」
- 描述位置:「置於頂部中央」、「在右下角」
- 使用引號: 在提示詞中將確切文字放在引號內
提示詞範例:
A clean white coffee mug sits on a wooden desk. The mug has the
text "GOOD MORNING" printed on it in bold black sans-serif letters,
centered and clearly legible. Warm morning light from the right
creates a soft shadow on the left side of the mug.
文字渲染何時有效,何時失敗
| 文字長度 | 成功率 | 最佳用途 |
|---|---|---|
| 1-3 個字 | 約 70% | 標誌、標籤、簡單招牌 |
| 4-6 個字 | 約 50% | 標題、簡短訊息 |
| 7 個字以上 | 約 25% | 避免——改用後製方式處理 |
對於任何需要大量文字的設計,請先生成不含文字的底圖,然後在 Canva、Figma 或 Photoshop 中加入排版。

常見錯誤與修正方法

問題: 你在使用逗號分隔的關鍵字。
修正: 改寫成完整句子,描述你腦海中看到的畫面。
錯誤:矛盾的光線
問題:「明亮的陽光,帶有深沉的陰影和柔和的陰天光線」
修正: 選擇一種光線情境並完整描述它。
錯誤:過多主體
問題: 6 個以上的人物或物體爭奪注意力。

常見問題
Nano Banana 2 提示詞應該多長?
理想長度是 50-150 個字。較短的提示詞適用於簡單的主體,但無法發揮模型的優勢。過長的提示詞則可能產生矛盾的指令。專注於描述的品質,而非字數。
我可以使用跟 Midjourney 一樣的提示詞嗎?
可以,但將標籤式提示詞轉換為完整句子會獲得更好的結果。Midjourney 適合使用關鍵字列表;Nano Banana 2 則偏好對同一場景的自然語言描述。
如何在多張圖像中保持角色面孔一致?
每次都以相同方式描述角色的外觀:相同的年齡、髮型、膚色、辨識特徵。使用相同的光線和鏡頭描述。為獲得最佳效果,請使用圖生圖模式並提供該角色的參考圖像。
Nano Banana 2 支援哪些長寬比?
Nano Banana 2 支援:1:1、16:9、9:16、4:3、3:4、3:2 和 2:3。與 Nano Banana Pro 不同,它不支援 21:9 或 8:1 等超寬格式。
結論
Nano Banana 2 以描述性強、結構良好的提示詞回饋令人驚豔的成果。從標籤式轉向句式提示詞是最大的調整——一旦掌握訣竅,你就能持續產出看起來精心設計且專業的圖像。
