根据这些提示，你可以进行以下操作：

• 文本生成图像：通过简单或复杂的文本描述生成高质量图像。
• 图像 + 文本生成图像（图像编辑）：提供一张图片，并使用文本提示词添加、删除或修改图像元素，调整风格或颜色。
• 多图合成与风格迁移：输入多张图片，合成新的场景，或将其中一张的风格迁移到另一张上。
• 迭代式优化：通过对话逐步优化图像，每次做小调整，直到达到理想效果。
• 文本渲染：生成包含清晰、布局合理文字的图像，适用于 logo、图表、海报等视觉创作。

谷歌强调，这些指令可以最大限度的发挥 Nano Banana 的图像生成能力。

接下来，我们看看这些提示具体包含的内容：

1、照片级写实场景

对于写实风格的图像，要像摄影师一样思考。prompt 中要提及机位角度、镜头类型、光线以及细节描写，这样可以引导模型生成更逼真的效果。

模板如下：

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.

代码块如下：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = 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()

下图使用的完整 prompt 为「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.」

2、风格化插画与贴纸

在制作贴纸、图标或项目素材时，在 prompt 中明确说明需要的风格；另外，如果需要白色背景，记得在 prompt 中提出来。

模板如下：

A [style] sticker of a [subject], featuring [key characteristics] and a [color palette]. The design should have [line style] and [shading style]. The background must be white.

代码块如下所示：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = client.models.generate_content( model="gemini-2.5-flash-image-preview", contents="A kawaii-style sticker of a happy red panda wearing a tiny bamboo hat. It's munching on a green bamboo leaf. The design features bold, clean outlines, simple cel-shading, and a vibrant color palette. The background must be white.",)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('red_panda_sticker.png') image.show()

下图使用的完整 prompt 为「A kawaii-style sticker of a happy red panda wearing a tiny bamboo hat. It's munching on a green bamboo leaf. The design features bold, clean outlines, simple cel-shading, and a vibrant color palette. The background must be white.」

3、图上添加精准的文字

Gemini 擅长渲染文字。此类任务最好在 prompt 中明确说明文字内容、字体风格（用描述性的方式），以及整体设计。

模板如下：

Create a [image type] for [brand/concept] with the text "[text to render]" in a [font style]. The design should be [style description], with a [color scheme].

代码块如下：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = client.models.generate_content( model="gemini-2.5-flash-image-preview", contents="Create a modern, minimalist logo for a coffee shop called 'The Daily Grind'. The text should be in a clean, bold, sans-serif font. The design should feature a simple, stylized icon of a a coffee bean seamlessly integrated with the text. The color scheme is black and white.",)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('logo_example.png') image.show()

下图使用的完整 prompt 为「Create a modern, minimalist logo for a coffee shop called 'The Daily Grind'. The text should be in a clean, bold, sans-serif font. The design should feature a simple, stylized icon of a coffee bean seamlessly integrated with the text. The color scheme is black and white. 」

4、产品模型与商业摄影

适合在电商、广告或品牌宣传时制作干净、专业的产品照片。

模板如下：

A high-resolution, studio-lit product photograph of a [product description] on a [background surface/description]. The lighting is a [lighting setup, e.g., three-point softbox setup] to [lighting purpose]. The camera angle is a [angle type] to showcase [specific feature].
Ultra-realistic, with sharp focus on [key detail]. [Aspect ratio].

代码块如下：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = client.models.generate_content( model="gemini-2.5-flash-image-preview", contents="A high-resolution, studio-lit product photograph of a minimalist ceramic coffee mug in matte black, presented on a polished concrete surface. The lighting is a three-point softbox setup designed to create soft, diffused highlights and eliminate harsh shadows. The camera angle is a slightly elevated 45-degree shot to showcase its clean lines. Ultra-realistic, with sharp focus on the steam rising from the coffee. Square image.",)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('product_mockup.png') image.show()

下图使用的完整 prompt 为「A high-resolution, studio-lit product photograph of a minimalist ceramic coffee mug in matte black, presented on a polished concrete surface. The lighting is a three-point softbox setup designed to create soft, diffused highlights and eliminate harsh shadows. The camera angle is a slightly elevated 45-degree shot to showcase its clean lines. Ultra-realistic, with sharp focus on the steam rising from the coffee. Square image.」

5、极简与留白设计

适合用于创建网站、演示文稿或营销素材的背景，并在其上叠加文字内容。

模板如下：

A minimalist composition featuring a single [subject] positioned in the [bottom-right/top-left/etc.] of the frame. The background is a vast, empty [color] canvas, creating significant negative space. Soft, subtle lighting. [Aspect ratio].

代码块如下：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = client.models.generate_content( model="gemini-2.5-flash-image-preview", contents="A minimalist composition featuring a single, delicate red maple leaf positioned in the bottom-right of the frame. The background is a vast, empty off-white canvas, creating significant negative space for text. Soft, diffused lighting from the top left. Square image.",)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('minimalist_design.png') image.show()

下图使用的完整 prompt 为「A minimalist composition featuring a single, delicate red maple leaf positioned in the bottom-right of the frame. The background is a vast, empty off-white canvas, creating significant negative space for text. Soft, diffused lighting from the top left. Square image.」

6、连续性艺术（漫画分镜 / 分镜头脚本）

通过逐格描绘，创作引人入胜的视觉叙事，适合用于开发分镜头脚本、漫画条幅或任意形式的连续性艺术。重点在于清晰的场景描述。

模板如下：

A single comic book panel in a [art style] style. In the foreground, [character description and action]. In the background, [setting details]. The panel has a [dialogue/caption box] with the text "[Text]". The lighting creates a [mood] mood. [Aspect ratio].

代码块如下：

from google import genaifrom google.genai import typesfrom PIL import Imagefrom io import BytesIOclient = genai.Client()# Generate an image from a text promptresponse = client.models.generate_content( model="gemini-2.5-flash-image-preview", contents="A single comic book panel in a gritty, noir art style with high-contrast black and white inks. In the foreground, a detective in a trench coat stands under a flickering streetlamp, rain soaking his shoulders. In the background, the neon sign of a desolate bar reflects in a puddle. A caption box at the top reads \"The city was a tough place to keep secrets.\" The lighting is harsh, creating a dramatic, somber mood. Landscape.",)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('comic_panel.png') image.show()

下图使用的完整 prompt 为「A single comic book panel in a gritty, noir art style with high-contrast black and white inks. In the foreground, a detective in a trench coat stands under a flickering streetlamp, rain soaking his shoulders. In the background, the neon sign of a desolate bar reflects in a puddle. A caption box at the top reads "The city was a tough place to keep secrets." The lighting is harsh, creating a dramatic, somber mood. Landscape.」

这一套 prompt 模板学下来，你大概就能掌握使用 Nano Banana 的精髓了。

不过，用户在使用中还有其他困扰，比如「在对已有图像进行编辑时，模型往往会返回一张一模一样的图像。」

另外有人指出了 Nano Banana 在编辑时存在的更多问题，「它在一致性上表现不如 Qwen 和 Kontext Pro，也不够稳定，特别是在持续对话过程中。对于文本转图像，直接用 Imagen 会更好且更可控。」
