Step 3: Write Your Text-to-Image Prompt

The quality of your output depends entirely on prompt quality.

Built on Gemini 3. Create and edit images with studio-quality levels of precision and control. Your prompt should include:

Basic Elements:

Subject (what you want to generate)
Setting (where the image takes place)
Style (photorealistic, illustrated, cinematic, etc.)
Technical specifications (resolution, aspect ratio, camera angle)

Example Prompt (Product Mockup):

"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. 4K resolution."

Example Prompt (Marketing Graphic with Text):

"Create a vibrant, eye-catching 'TYPOGRAPHY' design on a textured off-white background. The text should be bold, modern sans-serif, centered, with a gradient effect transitioning from deep blue to purple. Professional design, perfect for social media. High resolution."

Pro Tips for Prompts:

Be specific about dimensions and aspect ratios (9:16, 16:9, 1:1, etc.).
Specify resolution needs (1K, 2K, 4K).
Mention technical camera settings (f-stop, 45-degree angle, handheld, panoramic).
Include lighting descriptions (three-point lighting, golden hour, neon, moody).
Describe emotional tone (professional, playful, serious, energetic).
For text-heavy designs, explicitly state the text and formatting you want.

Step 4: Generate Your Image

Once your prompt is ready, generate your image.

Click "Generate" or "Create image" button.
Nano Banana Pro processes your request. Professional image editing made simple. Generate professional images in under 1 second - 10x faster than traditional AI models.
Your image appears in the canvas. Preview the result.
If unsatisfied, refine your prompt and generate again.

Step 5: Master Image Editing (The Most Powerful Feature)

Nano Banana Pro's real magic is its editing capability.

Once you have a generated image, you can make surgical edits using natural language. Examples:

Change Lighting:

"Change this image from daytime to night time while maintaining the subject. Add warm street lights and increase the dramatic effect."

Modify Objects:

"Replace the coffee mug with a red wine glass while keeping the same lighting setup and background."

Adjust Composition:

"Change the camera angle from a 45-degree shot to a bird's-eye view (top-down perspective)."

Transform Style:

"Make this photograph look like a watercolor painting while keeping the subject recognizable."

Edit Specific Elements:

"Brighten the subject's smile and change her hairstyle to long, wavy hair with side-swept bangs."

Preserve Brand Consistency:

Nano Banana Pro keeps your creative team in the driver's seat with our expanded visual context window. Think of this as "few-shot prompting" for designers: by allowing you to upload up to 14 reference images, you can now load a full style guide simultaneously—including logos, color palettes, character turnarounds, and product shots.

Upload your brand guidelines, color palettes, and logo variations. Then request: "Generate a product shot matching our brand guide using these reference images."

Step 6: Use Multi-Image Input for Complex Compositions

For professional design work, use multiple reference images.

Step-by-Step:

Upload up to 14 reference images showing:
- Style preferences
- Color palettes
- Character designs
- Product examples
- Layout inspiration
In your prompt, reference these images: "Using the color palette and style from these reference images, create a fashion editorial featuring these two models in a modern office setting."
Nano Banana Pro analyzes all references and produces output matching your brand identity.

Nano Banana Pro supports up to 14 input images and maintains resemblance for up to 5 people, with studio style controls for camera angle, depth of field, lighting, aspect ratios and upscaling to 1k, 2k and 4k resolutions.

Step 7: Advanced Creative Controls

Nano Banana Pro offers professional-grade adjustments.

Camera Controls:

Change from wide shot to close-up
Adjust depth of field (sharp focus vs. blurred background)
Modify camera angle and perspective
Create panoramic or standard aspect ratios

Lighting Adjustments:

Switch from daylight to night scene
Add specific lighting types (bokeh effect, volumetric lighting, chiaroscuro)
Adjust color temperature (warm to cool)
Create dramatic lighting effects

Color and Tone:

Adjust saturation and vibrancy
Change color grading
Apply filters and effects
Modify specific color ranges

Resolution Upscaling:

Generate at 1K, 2K, or 4K resolution for different use cases (social media, print, large displays).

Step 8: Enable Text Generation Control

One of Nano Banana Pro's standout features is text accuracy.

When including text in your design, be explicit:

Specify exact text to include ("Create a poster that says 'New Product Launch 2026'")
Request specific fonts (sans-serif, serif, decorative)
Define text styling (bold, italic, gradient, shadow)
Mention text positioning (centered, bottom-right, overlaid)

Generate images with accurate text in multiple languages, perfect for mockups, posters, and international content.

Example: "Create a professional poster for a fitness brand. Include the text 'Transform Your Body in 90 Days' in bold white sans-serif at the top. Include smaller text '1000+ Success Stories' at the bottom. Use vibrant blue and orange colors. High resolution for printing."

Step 9: Use SynthID Watermarking

All Nano Banana Pro outputs include SynthID watermarking.

We believe it's critical to know when an image is AI-generated. This is why all media generated by Google's tools are embedded with our imperceptible SynthID digital watermark.

What This Means:

Your images are automatically watermarked with an imperceptible digital signature proving they're AI-generated.
This is transparent and ethical—users can verify authenticity through the Gemini app.
For free tier users, a visible watermark appears. We will remove the visible watermark from images generated by Google AI Ultra subscribers and within the Google AI Studio developer tool.

Step 10: Export and Use Your Images

Once satisfied with your creation, export and use it.

Download Options:

Click "Download" to save your image in high resolution (up to 4K).
Supported formats: PNG, JPEG.
The SynthID watermark is embedded and invisible—no visible branding appears in final exports.

Commercial Use:

For commercial projects, verify you have proper rights to any reference images used.
Ensure your generated images don't violate anyone's intellectual property.
Include appropriate AI disclosure in marketing materials ("This image was created with AI").
