The Ultimate Guide to Google Nano Banana Prompts: 6 Pro Tips to Make You a Master of AI Image Generation

Feel like your AI-generated images are always missing something? That’s because you haven’t mastered the true ‘art of prompting’! This article will reveal 6 professional prompting techniques for Google’s latest AI model, Nano Banana (Gemini 2.5 Flash). We’ll provide complete bilingual (Chinese-English) instructions, from photorealistic scenes to commercial posters, teaching you how to give precise commands and turn your wildest ideas into reality.

The development of AI image generation technology is astonishingly fast. Works that once required professional artists to spend a great deal of time can now be rendered by AI in an instant with just a few commands. But here’s the question: why can some people create god-tier images, while our results are always a bit… lacking?

The real secret lies in how we communicate with AI—in what’s known as “prompting” or the “art of the prompt.”

Recently, Google launched their newest, fastest, and most efficient AI model, Nano Banana (also known as Gemini 2.5 Flash Image). The power of this model lies in its native multimodal architecture, which can process text and images simultaneously in one step, unlocking powerful features like conversational editing, multi-image synthesis, and more precise logical reasoning.

Want to harness this power? It all stems from one fundamental principle: try to describe a complete scene, not just throw out a bunch of scattered keywords.

Gemini’s core advantage is its deep understanding of language. A narrative, descriptive paragraph will almost always produce a better, more coherent image than a jumble of disconnected words. Today, we’re going to break down 6 practical prompting techniques to help you master the image generation magic of Nano Banana.

Google AI Studio provided Six text-to-image prompting tips for Nano Banana on X (Twitter).

So, how exactly should you give commands?

Before diving into various scenarios, let’s first look at the core features Nano Banana offers to understand its capabilities:

• Text-to-image: Generate high-quality images from simple or complex text descriptions.
• Image + text-to-image: Provide an existing image and use text commands to add, remove, or modify elements, or even change the style or adjust colors.
• Multi-image to image: Use multiple input images to synthesize a new scene or transfer the style of one image to another.
• Iterative refinement: Like a chat, gradually refine your image through multiple rounds of conversation until it’s perfect.
• Text rendering: Generate clear, well-placed text within images, perfect for logos, charts, or posters.

Ready? Let’s get started!

Tip 1: Think Like a Photographer—Create Photorealistic Scenes

Want your AI-generated photos to look real? Then you need to think like a professional photographer. What does a photographer consider before a shoot? Light, angle, lens, depth of field… tell the AI all these elements, and it will surprise you.

Template:

Template: 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.

Example Prompt:

Example Prompt: 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.

Tip 2: Be a Designer—Stylized Illustrations & Stickers

Sometimes, what you need isn’t realism, but a unique style, like for a cute sticker, a website icon, or a small asset for your project. The key to the prompt here is to “clearly define the style.” And don’t forget, if you need an image with a transparent background, be sure to add “white background.”

Template:

Template: 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.

Example Prompt:

Example Prompt: 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.

Tip 3: Precision is King—Adding Accurate Text to Images

In the past, getting AI to generate accurate text in images has been a major challenge. But Gemini performs remarkably well in this area. The trick is to clearly state the text content, font style, and overall design sense.

Template:

Template: 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].

Example Prompt:

Prompt: 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.

Tip 4: A Must for E-commerce—Product Mockups & Commercial Photography

Need professional product photos for your online store or ad campaign? No need to spend a fortune renting a studio. Just learn to describe the lighting and setting, and AI can handle it for you.

Template:

Template: 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].

Example Prompt:

Example Prompt: 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.

Tip 5: The Art of White Space—Minimalist & Negative Space Design

Sometimes, less is more. A good background image needs enough “negative space” (or white space) for text or other elements to stand out. This is especially important when creating website banners, presentations, or marketing materials.

Template:

Template: 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].

Example Prompt:

Example Prompt: 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.

Tip 6: Tell a Good Story—Sequential Art (Comic Panels / Storyboards)

AI can not only generate single images but also help you create visual narratives. Whether it’s a comic, a storyboard, or any form of sequential art, the key is to clearly describe the scene details of each panel.

Template:

Template: 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].

Example Prompt:

Example Prompt: A single comic book panel in a film noir style. In the foreground, a detective in a trench coat stands with his back to the viewer, rain slicking 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.
