剛剛！谷歌推出Nano Banana官方終極指南：六條保姆級權威提示教程，拿走不謝

直接和官方學習最頂級的nano banana 提示技巧，這比你看多少碎片文章和視頻都強

Nano Banana 太火了，谷歌趁熱打鐵，剛剛推出了官方認證的的Nano Banana使用指南，指南一共有六條提示詞模板和具體示例，可以在 Google AI Studio (ai.studio/banana) 中立即體驗這些功能，或通過官方文檔中的代碼進行調用

不熟悉的同學可以速覽一下Nano Banana（即 Gemini 2.5 Flash Image 圖像模型） 的核心功能：

文生圖 (Text-to-image): 從簡單或復雜的文本描述中生成高質量圖像

圖+文生圖 (編輯): 提供一張圖片，通過文本指令添加、移除或修改元素，改變風格或調整色彩

多圖生圖 (合成與風格遷移): 使用多張輸入圖像來構圖新場景，或將一張圖像的風格遷移到另一張上

迭代優化: 通過多輪對話逐步優化圖像，進行微調直至完美

文字渲染: 生成包含清晰、位置得當文字的圖像，非常適合用于徽標、圖表和海報

本指南將教會你如何編寫有效的提示詞 (prompt) 和指令，以充分發揮 nano banana 的潛力。這一切都始于一個基本原則：

描述場景，而非羅列關鍵詞，nano banana 的核心優勢在于其深度的語言理解能力。與一堆零散的關鍵詞相比，一段敘事性的、富有描述力的段落幾乎總能生成更優質、更連貫的圖像

廢話不多說，直接上干貨

Nano Banana 六大提示詞技巧 1. 創造照片級真實感場景

想要獲得逼真的圖像，要像攝影師一樣思考。提及相機角度、鏡頭類型、光線和精致細節，將引導模型創造出照片級的效果

模板 :

一張照片級的[拍攝類型]照片，主體是[主體]，正在[動作或表情]，場景位于[環境]。由[光線描述]照亮，營造出[氛圍]的氛圍。使用[相機/鏡頭細節]拍攝，突出了[關鍵紋理和細節]。圖像應為[寬高比]格式

A photorealistic [shot type] of [subject], [action or expression], set in [environment]. The scene is illuminated by [lighting description], creating a [mood] atmosphere. Captured with a [camera/lens details], emphasizing [key textures and details]. The image should be in a [aspect ratio] format.

示例提示詞:

一張照片級的特寫肖像，主角是一位年邁的日本陶藝家，他臉上布滿被陽光雕刻出的深深皺紋，帶著溫暖而會意的微笑。他正在仔細端詳一個剛上釉的茶碗。背景是他那間充滿陽光的鄉村風格工作室。柔和的金色黃昏光線從窗戶射入，照亮了黏土的細膩紋理。使用 85mm 人像鏡頭拍攝，背景柔和模糊（焦外成像）。整體氛圍寧靜而充滿大師風范。豎向構圖

A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl. The setting is his rustic, sun-drenched workshop. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful. Vertical portrait orientation.

from google import genai from google.genai import types from PIL import Image from io import BytesIO client = genai.Client() # Generate an image from a text prompt response = client.models.generate_content(     model="gemini-2.5-flash-image-preview",     contents="A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl. The setting is his rustic, sun-drenched workshop with pottery wheels and shelves of clay pots in the background. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay and the fabric of his apron. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful.", ) image_parts = [     part.inline_data.data     for part in response.candidates[0].content.parts     if part.inline_data ] if image_parts:     image = Image.open(BytesIO(image_parts[0]))     image.save('photorealistic_example.png')     image.show()

要為項目創建貼紙、圖標或設計素材，請明確說明所需的風格，并記得在需要時要求使用白色背景

Gemini 非常擅長渲染文字。在提示詞中清晰地寫出文本內容、描述字體風格以及整體設計。

模板 :

為[品牌/概念]創建一個[圖像類型]，包含文字“[要渲染的文本]”，字體為[字體風格]。整體設計應為[風格描述]，配色方案為[配色方案]
